Application Description

Eaton’s Load Interrupter Type MVS metal-enclosed switchgear provides safe, reliable switching and fault protection for medium voltage circuits rated from 2.4–38 kV. The MVS switch is ideal for applications where high duty cycle operation is not needed.

MVS switchgear has the advantage of low initial cost inherent in switch designs while offering the characteristics most vital to safety and coordination.

The MVS switch’s quick-make, quick-break mechanism provides full-load current interrupting capability while fuses provide accurate, permanently calibrated short circuit detecting and interrupting capabilities. Visibility of actual blade position improves safety by giving positive assurance of circuit de-energization.

Standard MVS switchgear meets or exceeds the following industry standards:

5 and 15 kV MVS switchgear assem-blies are available as listed products with

Underwriters Laboratories

and

Canadian Standards Association

for most options. In addition, 27 and 38 kV MVS switchgear assemblies are available with CSA/US listing to U.S. standards with a limited number of options.

Load interrupter switches should not be used to interrupt load currents above their interrupting rating of 600 or 1200A, as they are not designed nor tested for interrupting fault currents on electrical systems. Optional fuses can be provided for phase overcurrent protection

Typical Switch with Front Door Open

�

Switch Mechanism

Quick-make, quick-break stored energy operation.

The opening and closing of the switch blades is done by the operating spring. An operator’s actions only charge and release the operating spring.

The switch blades cannot be teased to any intermediate positions. During the closing operation, full clearance between blades and stationary contacts is maintained until the switch mechanism goes over toggle.

The switch mechanism has only metal-to-metal linkage—no chains or cables are used.

Arc interruption takes place between copper-tungsten tipped auxiliary (flicker) blade and arcing contacts with a DE-ION

®

arc chute; no arcing takes place between the main blades and the stationary contacts to pro-long the life of the main blades.

Blow-out forces cannot be transmit-ted to the operating handle.

�

Provisions for Padlocking Door

Handle not visible in the photo.

�

Inspection Window

A large 8.00-inch x 16.00-inch (203.2 x 406.4 mm) gasketed, rectangular, high impact viewing window permits full view of the position of all three

switch blades through the closed door.

�

Full Height Main Door

The door has a return flange and two rotary latch-type handles to provide latching members held in shear. It closes over a projecting frame.

�

Foot-Operated Door Stop

�

Grounded Metal Safety Barrier

Prevents inadvertent contact with any live part, yet allows full-view inspec-tion of the switch blade position.

�

Door Interlock

Prevents the door of the enclosure from being opened when the switch is closed.

General Description

Switch Mechanism

The quick-make, quick-break mecha-nism uses a heavy-duty coil spring that provides powerful opening and closing action. To close the switch, the handle is inserted into the spring charging cam, then rotated upward through an angle of 120 degrees. This action charges the operating spring, and as the mechanism is forced past toggle, the stored energy of the spring is released and transferred to the main shaft that snaps the switch closed.

As a result of the over-toggle action, the blades are moved independently of the operator. It is impossible to tease the switch into any intermediate position.

To open the switch, the handle is inserted into the spring charging cam and rotated downward through 120 degrees resulting in charging of the operating spring, then releasing its stored energy in similar sequence.

Quick-Break DE-ION Arc Interruption

With the switch closed, both main and auxiliary (flicker) blades are closed, and all of the current flows through the main blades. The flicker blades are in the closed position in the arc chutes, but are past the arcing contacts and thus carry no current.

As the main blades open, current is transferred momentarily to the flicker blades, which are held in the arc chutes by high pressure contact fingers. There is no arcing at the main blades.

When the main blades reach a pre-determined angle of opening, a stop post on the main blades prevents further angular movement between the main and flicker blades. This starts the flicker blades out of the high pressure contacts in the arc chutes and as contacts are broken, the flicker blades are snapped into position by their torsion springs.

The heat of the arc, meanwhile, releases a blast of de-ionizing gas from the gas-generating material of the arc chute. This combination of quick-break and DE-ION action quickly extinguishes the arc and the circuit is safely de-energized.

A non-fused switch has the ability to close and latch four times when rated 40 kA fault close, and one time when rated 61 kA fault close, and continue to carry rated current thus adding a large margin of integrity to the electrical system.

The 5/15 kV switch designs have also demonstrated the ability to surpass the number of ANSI C37.22 required loadbreak current operations by no less than 200%.

Technical Data

Test DataAll Eaton’s MVS switch ratings have been thoroughly tested in recognized high power laboratories with certified inspectors from both UL and CSA organizations. Tests were performed to substantiate all published ratings in accordance with ANSI, IEEE, CSA and NEMA standards.

The testing program included tests of:

■ Basic impulse levels■ Momentary withstand■ Short-time withstand■ Fault closing■ Load interrupting at various loads,

various power factors■ Mechanical life tests■ Temperature rise test

These tests verified not only the per-formance of the switch and integrated switch-fuse assembly, but also the suitability of the enclosure venting, rigidity and bus spacing.

The mechanical life test subjected the MVS switch to a number of no load cycles greater than the requirements tabulated in ANSI C37.22 standards. There were no moving or current carrying part failures as a result.

The Fault Close and Load Interrupting test demonstrated significant improved performance above ANSI/IEEE standards. See Tables 8.0-3 and8.0-4 for results.

Eaton's Cooper Power Systems has set the standard for design, manufacturing and delivery of polymeric distribution-class arresters with UltraSIL™ polymer-housed arrester family. UltraSIL polymer-housed surge arrester incorporates the industry recognized superior polymer housing material – silicone rubber.

Available in Normal Duty, Heavy-Duty and Riser Pole classifications, UltraSIL polymer-housed VariSTAR™ distribution-class surge arresters provide superior overvoltage protection for any electric distribution system.

ConstructionThe patented construction of UltraSIL polymer-housed arresters begins with Metal Oxide Varistors (MOVs) manufactured at our Olean, NY facility. Manufacturing our own MOVs allows for strict quality control over all aspects of disk production. Every MOV must pass a series of physical and electrical tests designed to ensure that only disks meeting strict quality standards are used in UltraSIL arresters. Eaton's Cooper Power Systems MOV disk design has proven its reliability and protective ability through many years of field service.

The MOV disks are combined with aluminum end electrodes and are encapsulated in a high-strength composite wrap insulating material on our fully automated assembly line using strict quality control processes that eliminate manufacturing variances. The composite collar is cured to the MOV disk stack to form a solid insulation MOV disk module system that is inserted and bonded to the industry leading track resistant UltraSIL silicone rubber housing.

This exclusive Eaton's Cooper Power Systems patented manufacturing process forms a secondary moisture seal under the primary silicone rubber housing seal, which makes the arrester impervious to moisture and capable of withstanding extreme electrical, environmental and cantilever load conditions. The composite wrapped UltraSIL polymer-housed arrester design represents a quantum leap in polymer arrester technology.

Following assembly, each arrester is subjected to a battery of electrical tests to assure the highest quality and in-service field performance.

General

Technical Data 235-35Effective June 2014Supersedes January 2012

FeaturesUltraSIL silicone rubber polymer-housing has undergone a wide range of design tests to determine the optimum shed configuration. In addition, long term environmental testing has verified the lifetime superiority of silicone rubber when compared to other polymeric insulating materials.

Independent laboratory tests have verified the superiority of silicone rubber in terms of non-wetting surfaces, resistance to UV degradation and surface tracking, performance in contaminated environments, chemical inertness, temperature stability and other important insulating properties. UltraSIL silicone rubber polymer-housing will not support biological growth (algae and mildew), is non-flammable and will not support combustion.

An optional insulated mounting base is available to allow connecting to a wide variety of brackets. The insulated base, made of glass filled polyester, has been designed to provide needed mechanical strength for installation and severe loading conditions.

A ground lead isolator is also available. The isolator removes the ground terminal from the arrester in the unlikely event of arrester failure, thus preventing a permanent system fault. An isolator that has operated gives visual indication of internal damage to the arrester and the need for arrester replacement. See Figure 2 for the isolator operating characteristics.

The optional universal wildlife protector has two self-adjusting "valve" style openings which vary from 0 to 0.75" in diameter, thus allowing for a large variety of conductor/insulation sizes while providing optimum wildlife protection. (See page 11, Figure 8 for a dimensional diagram.)

Customers looking to improve system reliability by minimizing wildlife related outages now have multiple options. In addition to the universal wildlife protector featuring two self-adjusting "valve" style openings, Eaton's Cooper Power Systems also offers the more robust line terminal wildlife guard. The line terminal wildlife guard is easily retrofitted to existing arresters installations and provides increased electrical insulation for the high-voltage terminal of the

arrester. The flexible design of the line terminal wildlife guard allows insertion of the lead wire through the bottom of the integral molded flanges. The access holes molded above the flanges will allow conductor sizes ranging from 0 to 0.50” in diameter (OD). The line terminal wildlife guard geometry allows water to shed away from the surface area of the animal guard while minimizing ice build up and maintaining flexibility through extreme operating temperatures. (Refer to page 11, Figure 9 for a dimensional diagram.)

For complete wildlife resistance, the ground terminal wildlife guard can easily be installed alongside the line terminal wildlife guard or universal wildlife protector. The ground terminal wildlife guard is a compact and economical guard that ensures wildlife is unable to come in contact with energized objects while on a grounded surface.(Refer to page 11, Figure 10 for a dimensional diagram.)

OperationThe operation of VariSTAR arresters is typical of gapless metal oxide arresters. During steady state conditions, line-to-ground voltage is applied continuously across the arrester terminals. When surges occur, VariSTAR arresters immediately limits the overvoltage to the required protective level by conducting the surge current to ground. Upon passage of the surge, the arrester returns to its initial state, conducting minimal leakage current.

The protective characteristics of VariSTAR arresters provide excellent overvoltage protection for distribution system equipment. (See page 6 for protective characteristics.)

Design testingThe housing material, internals and hardware work together as a system and must stand up to years of exposure to environmental extremes.

To assure a superior level of performance, both the components and the assembled arrester units have been subjected to a program of testing that accurately simulates years of exposure to actual field conditions. Testing includes:• IEEE Std C62.11-2005™ standard Testing – Full certification to

the performance requirements by an independent laboratory. A certified test report is available under Bulletin Number 95062. Additional reference documents are listed on page 14.

Production testsA complete production test program ensures a quality product. Each metal oxide varistor receives a series of electrical tests. Quality is demonstrated by a series of destructive tests performed on every batch of varistors. Listed are the tests performed on the varistors:• 100% Physical Inspection• 100% Discharge Voltage test• 100% V1mA/cm2

• 100% Leakage Current at 80% of V1mA/cm2 Voltage (Watts Loss)• Batch High-current, Short-duration test• Batch Thermal Stability test• Batch Aging test

Each fully assembled VariSTAR arrester must pass the following production tests:• 100% Physical Inspection• 100% Leakage Current test • 100% Partial Discharge Inception Voltage test

General application recommendationsThe rating of an arrester is the maximum power frequency line-to-ground voltage at which the arrester is designed to pass an operating duty-cycle test. Table 1 provides a general application guide for the selection of the proper arrester rating for a given system voltage and system grounding configuration as outlined in the IEEE Std C62.22™ standard application guide.

Under fault conditions and other system anomalies, higher voltages can be experienced by the arrester. To ensure that the arrester ratings will not be exceeded, Eaton's Cooper Power Systems application engineers are available to make recommendations. The following information is normally required:

1. System maximum operating voltage.

2. System grounding conditions.

A. For four-wire circuits, grounding conditions depend upon whether the system is multi-grounded, whether it has a neutral impedance and whether common primary and secondary neutrals are used.

B. For three-wire circuits, grounding conditions depend upon whether the system is solidly grounded at the source, grounded through neutral impedance at the source transformers or ungrounded.

Consult your Eaton's Cooper Power Systems representative to have your individual system application needs reviewed.

Performance test characteristicsVariSTAR distribution-class arresters withstand the following design tests as described by IEEE Std C62.11-2005™ standard:• Duty Cycle:

Normal-Duty: 22 current surges of 5 kA crest, 8/20 µs waveshape.Heavy-Duty and Riser Pole: 20 current surges of 10 kA crest, 8/20 µs waveshape followed by 2 current surges of 40 kA crest, 8/20 µs waveshape.

• High-current, Short-duration Discharge: Normal-Duty: 2 current surges of 65 kA crest, 4/10 µs waveshape.Heavy-Duty and Riser Pole: 2 current surges of 100 kA crest, 4/10 µs waveshape.

• Low-Current, Long-Duration Discharge: Normal-Duty: 20 current surges of 75 A crest 2000 µs duration rectangular wave. Heavy-Duty and Riser Pole: 20 current surges of 250 A crest 2000 µs duration rectangular wave.

Following each of these tests, the arresters remain thermally stable as verified by:• Continually decreasing power values during a thirty minute power

monitoring period.• No evidence of physical or electrical deterioration.• The 5 kA (normal-duty) or 10 kA (heavy-duty and riser pole) discharge

voltages measured after each test changed less then 10% from the initial values.

In addition, full IEEE Std C62.11-2005™ standard certification has been completed and verified.

Fault current withstand testsFault current withstand tests demonstrate the ability to withstand fault currents for specific durations without expelling any internal components. All VariSTAR arrester designs have been tested in accordance with the requirements listed in IEEE Std C62.11-2005™ standard, and are non-fragmenting to the levels shown in Table 2.

Temporary overvoltage (TOV) capabilityThe ability to withstand 60 Hz overvoltage conditions [Temporary Overvoltage (TOV)] is shown in Figure 7 for all VariSTAR distribution-class arresters. The graph shows for a given voltage magnitude (on a Per Unit of MCOV basis), the time an arrester can survive a TOV condition without going into thermal runaway.

Ordering informationVariSTAR distribution-class arresters from Eaton's Cooper Power Systems are supplied in a variety of customer defined options. The catalog system employed lets the number define the features of the arrester. Table 9 shows the catalog numbers for several of the most common arrester styles. Table 10 shows what each alpha-numeric character in the catalog number represents and lists several of the available options defined by these characters. A wide variety of option combinations are available, allowing users to customize the arrester to their specific needs. For further options contact your Eaton's Cooper Power Systems sales engineer.

Application Considerations and Definitions

Eaton’s Pow-R-Line

®

family of distribution switchboards incorporates new design concepts that fit the ever-increasing need for applications on high short circuit systems, while retaining maximum flexibility, safety and convenience throughout the line.

Front Access

Front-access switchboards align at the rear, enabling them to be placed against a wall (Type Pow-R-Line C™ front accessible). If the main section is deeper than others, due to physical size of the main device, the necessary offset in lineup will occur in front, and the main section will be accessible from the side as well as from the front. Eaton also offers front accessible switchboards that align at the front and rear.

Rear Access

Rear-access switchboards align at the front and the rear. Bus maintenance and cable entry and exit require rear access. There are two types of rear accessible switchboards. Both types use the same incoming utility and/or main structures. The first type uses group-mounted feeder devices with panel construction (Type Pow-R-Line C rear accessible). The second type uses individually compartmentalized feeder devices with load side insulated bus bar extensions (Type Pow-R-Line

i

).

Individually Mounted

Larger overcurrent protective devices (OCPD) may be individually mounted. In most cases, this means that the OCPD is mounted vertically in the switchboard and is connected via bus bar. All insulated case circuit breakers, power air circuit breakers and bolted pressure contact switches are individually mounted. Molded-case circuit breakers 600A and above may be individually mounted when used as a main or as a feeder device feeding other OCPD within a section or adjacent sections.

Compartmentalized Feeder and Branch Devices

Compartmentalized molded-case circuit breakers and fusible switches provide additional isolation. Individually mounted molded-case circuit breakers and fusible switches through 1200A are available in a compartmentalized, rear-access,

rear-connected switchboard. See Pow-R-Line

i

switchboards in this section for details.

Standard Switchboard Height

Standard Pow-R-Line switchboard height is 90.00 inches (2286.0 mm). Contact Eaton for special heights.

Group Mounting

Group-mounted circuit protective devices are an assembly of units mounted on a panelboard type chassis. Units may be molded-case breakers, fusible switches, customer metering and surge protective devices.

A main molded-case breaker or main fusible switch, within the sizes listed for panelboard design, can be included in the panel-mounted assembly in lieu of a separate, individually mounted unit.

Space Only for Future Devices Group-Mounted Construction

Where space only for future circuit protective devices is required, the proper space and a blank filler plate will be supplied. Connections and mounting hardware are not included.

Provision for Future Devices

Where provisions for future circuit protective devices are required, space for the device, corresponding vertical bus, device connectors and the necessary mounting hardware will be supplied.

Bus Bar System

Standard bus in the switchboards is tin-plated aluminum. Copper, silver-plated copper or tin-plated copper are also available.

Main bus and sub-main buses meet UL

®

and NEMA

®

standards for temperature rise on all Pow-R-Line switchboards. Special density rated bus is available.

Overcurrent Devices

To properly select and size overcurrent devices for use in a switchboard, the allowable temperature rise must be taken into account as to its effect on the tripping characteristics of the devices in question per UL 891.

Accordingly, the NEC

®

requires overcurrent devices to be rated not less than 125% of the continuous load they are protecting. To comply with this, an 80% derating factor must be used with all overcurrent devices such as molded-case

breakers and FDPW fusible switches unless they are tested and listed for application at 100% of the rating. All Magnum type breakers and bolted pressure switches are 100% rated.

Short-Circuit Rating

Standard bus and connectors on all switchboards are rated for use on systems capable of producing up to 65,000A rms symmetrical short-circuit current at the incoming terminals.

Increased bus short-circuit ratings equal to that of connected switchboard devices, up to 200,000A rms symmetrical, are available in most Pow-R-Line C switchboards when approved main devices are installed. UL labeled switchboard sections are marked with their applicable short-circuit rating.

When air power circuit breakers are used as feeder devices in a switchboard, these devices may experience up to a 30-cycle (1/2 second) delay if the instantaneous setting is turned off. Eaton has qualified our low voltage switchboards when air power circuit breakers are used as feeders (and mains) to 30 cycles. This rating is not recognized under the UL 891 standard. However, Eaton has witness tested the structure bussing with a qualified National Recognized Testing Laboratory (NRTL) at 30 cycles (1/2 second) up to 100 kAIC symmetrical.

Provision for Busway Entrance and Exit

Busway connections to switchboard sections include cutout and drilling in the top of the switchboard with riser connections from the switchboard device or bus, up to the point where the bus duct enters the switchboard. No connections are furnished external to the switchboard.

In all transactions involving busway attached to switchboards, it is essential that information regarding orientation of the busway with respect to the front of the switchboard be supplied to the coordinating assembly plant.

On Pow-R-Line C switchboards, a solid bus bar is used to connect the bus duct to the individually mounted main device, main or sub-main switchboard bus, or vertical main bus of panel-mounted circuit protective device panels.

Busway fed by group-mounted branch devices are cable connected.

Aluminum riser connections are standard. Copper- or silver-plated copper is available as an option.

Transitions

Transition structures are required for connecting switchboards to the secondary of power center transformer (fluid filled), motor control centers, and for other special switchboard configurations such as “L” or “U” shaped lineups. In some applications, an extra structure complete with connections is required; in others, where switchboard depth and space permit, only the connection conductors are required. Refer to Eaton for these applications.

Auxiliary Structures

These are normally mounted adjacent to service structures or distribution structures, and used where incoming service or feeder conductors require additional space or facilities not included in the standard switchboard, such as:

1. Mounted adjacent to a topconnected service structure and used as a cable pull structure where service conductors are brought in underground. Auxiliary structures are the same depth and height as the service structure, and are wide enough to accommodate the incoming cables.

2. Mounted adjacent to a service structure and used as a bus transition compartment for running riser bus from the load-side of the service structure up to top outgoing bus duct connection when distribution structures are not required. Auxiliary structures are the same depth and height as service structures.

In addition to the above applications, auxiliary structures may be mounted adjacent to a distribution structure and used as a structure for lighting panel or other device that may be cable-connected to a branch circuit device in the distribution structure. Dimensions are compatible with the arrangements required.

Switchboards Used as Service Equipment

Service equipment is the electrical equipment that constitutes the main control and means of power cutoff the electric service (normally Power Company supply) brought into the building.

Where switchboards are to be used as service equipment, certain NEC and UL requirements apply that necessitate modifications not normally supplied in switchboards.

The following is a summary of the requirements that are pertinent to the application of a switchboard for service equipment:

A. A switchboard with main lugsonly (no main disconnect) must be designed so that all circuits in the switchboard can be disconnected from the supply source by the operation of no more than six operating handles (breaker or switch).

Switchboard equipped with main disconnect devices are not subject to the above six disconnect limitation, as the entire board can be de-energized with the main disconnect device.

Ground fault protection of equipment must be provided for solidly grounded wye electrical services of more than 150V to ground, but not exceeding 600V phase-to-phase for each service disconnecting means rated 1000A or more.

B. For testing purposes, means are also required to disconnect the switchboard neutral bus from the

grounded service neutral conductor

(single-phase, three-wire; and three-phase, four-wire systems). To comply with this requirement, a removable link (solid bar) is provided in the switchboard neutral bus. This link is generally located near the point where the main feeders enter the switch-board or in the area of the main disconnect device where one is provided.

To further comply with NEC and UL requirements, a separate bonding strap is connected from the neutral bus to the switchboard frame. This bonding connection is located on the line side of the removable neutral link, maintaining a service ground to the switchboard frame when the test link is removed. See

Figure 21.0-1

Underwriters Laboratories Requirements and Labeling

The basic requirement for obtaining a UL label on a switchboard, is that all the component devices (breakers, switches, and so on) in the switchboard assembly are UL listed. In addition, the switchboard must comply with all applicable provisions of UL 891.

Today’s modern electrical systems require that switchboards offer a wide selection of electrical devices, many of which do not fall within the scope of UL listed devices. Therefore, the conditions under which a switchboard may be labeled are limited.

Listed below are several important guidelines for consideration when aUL label is specified:

1. UL nameplates, where applicable, are supplied for each vertical structure rather than one common nameplate for the complete switchboard lineup. Where all of the component devices in the switchboard are UL listed and all applicable provisions of UL 891 are met, each of the switchboard sections may be labeled.

2. Individual vertical structures of a switchboard may be labeled where they comply with UL requirements, although other vertical structures in the same switchboard lineup may not meet the UL standards, and will not be labeled.

3. All Pow-R-Line C switchboards are UL labeled when all mounted devices are UL listed.

Alternate Power Source Capabilities

Multiple solutions are available to accommodate alternate power sources available. Due to the large number of customer and system requirements, details are not provided in this guide. Eaton offers solutions that include main-main configuration and main-tie-main configurations. Automatic transfer equipment, including UL 1008 listed transfer switches and other automatic transfer schemes, are available.

Automatic Transfer Equipment

For continuity of service, automatic transfer equipment between two incoming sources may be required. This equipment transfers the load upon failure of the normal (or preferred) source to the standby (or alternate) source. Upon restoration of the normal source, the load is automatically transferred back to it. To accomplish this, electrically operated main protective devices (and bus tie devices, if required) must be employed. Additional relays also are required to detect source voltage failure and to transfer control

power, when required. A manual selector

switch is usually provided to select the mode of operation—automatic or manual transfer.

Magnum SB Low Voltage Insulated-Case Circuit Breakers

Magnum SB Low Voltage Insulated-Case Circuit Breakers are Designed for the Performance and Economic Requirements of UL 891 Switchboards

Typical Magnum SB Low Voltage Insulated-Case Circuit Breaker Nameplate

Magnum SB is a low voltage insulated-case circuit breaker family designed for the performance and economic requirements of UL 891 switchboards.

■ Magnum SB insulated-case circuit breakers have Interruption ratings up to 100 kA at 635 Vac with continu-ous current ratings up to 6000 A

■ Magnum SB insulated-case circuit breakers have lighter-duty short-time current ratings and fixed internal instantaneous trips on most ratings, which is characteristic of UL 489 molded-case breakers commonly used in UL 891 switch-boards. This provides for greater economy and excellent coordination and selectivity for most commercial applications

■ Fixed internal instantaneous trips are included on all SB insulated-case circuit breakers rated 3200 A and below to provide an extra safety factor by reducing the energy let-through to downstream circuits at the maximum instantaneous trip point and to facilitate feeder circuit breaker protection in UL 891 switch-boards with 3-cycle bus bracing

■ Magnum SBSE current limiting power circuit breakers have 150 kA interrupting ratings at 480 Vac with continuous current ratings up to 5000 A. The short-time current rating is 30 kA for standard frame and 50 kA for double frame breakers

UL and ANSI Test CertificationsMagnum SB meets or exceeds the applicable ANSI, NEMA, UL and CSA standards, including:

■ ANSI C37.13 (low voltage AC power circuit breakers used in enclosures)

■ ANSI C37.16 (preferred ratings, related requirements, and application recommendations for low voltage power circuit breakers and AC power circuit breakers)

■ ANSI C37.17 (trip devices for AC and general purpose DC low voltage power circuit breakers)

■ ANSI C37.50 (test procedures for low voltage AC power circuit breakers used in enclosures)

■ UL 1066 (standard for low voltage AC and DC power circuit breakers used in enclosures)

■ NEMA SG3 (this standard adopts ANSI C37.16 in its entirety)

Universal Remote Power Racking System (Type RPR-2)

Remote Power Racking System

For maximum safety during drawout breaker levering operations, the universal remote power racking system (RPR-2) can be employed on Magnum, as well as other drawout low and medium voltage power circuit breakers that use rotation of a shaft for insertion or removal. Remote control is accom-plished by an operator pendant with an INSERT and REMOVE pushbutton station and a 25-foot connecting cable. The RPR-2 requires 120 Vac, 15 A power from a common plug receptacle. Status indication and selectable torque limitation matched to the breaker racking mechanism are also provided.

Lifting Yoke and Floor Lifting DeviceMagnum breakers include lifting ears on each side to accept a lifting yoke (or suitable sling) to facilitate lifting using a skyhook from a top of gear lifter, floor lifter or crane. Various lifting yoke style numbers are available for all Magnum frame types in both three-pole and four-pole configurations.

A roll-on-the-floor lifting device style number 6727D63H20 is equipped with a skyhook for use in conjunction with a breaker lifting yoke or suitable sling to lift the breaker from above. Shelf-type roll-on-the-floor lifters can also be used to lift the breaker from underneath without a lifting yoke.

Internal AccessoriesNote: For a complete listing of available external accessories, see Volume 4—Circuit Protection Catalog, CA08100005E, Section 25.

All internal accessories are of the plug-in type and are listed for field installation under UL File E64983. Internal accessories for sealed circuit breakers are listed under UL File E7819 for factory installation only. The available plug-in accessories include the following:

■ Alarm (signal)/lockout switch■ Auxiliary switch■ Shunt trip■ Low energy shunt trip■ Undervoltage release mechanism

Typical Internal Plug-in Accessory Installed in K-Frame Circuit Breaker

Different accessory wiring options are available to satisfy most circuit breaker mounting applications. The standard wiring configuration is pigtail leads exiting the rear of the base directly behind the accessory. Optional configurations include a terminal block mounted on the same side of the base as the accessory, leads exiting the side of the base where the accessory is mounted, and leads exiting the rear of the base on the side opposite the accessory. If accessory leads longer than 18.00 inches (457.2 mm) are required, side-mounted terminal blocks should be used.

Alarm (Signal)/Lockout SwitchThe alarm (signal)/lockout switch monitors circuit breaker trip status and provides remote signaling and inter-locking capabilities when the circuit breaker trips. For two-, three- and four-pole circuit breakers, the alarm (signal)/lockout switch consists of one or two SPDT switches assembled to a plug-in module mounted in retaining slots in the top of the trip unit. The SPDT switch contacts are identified as make and break contacts. When the circuit breaker trips, the make contact closes and the break contact opens.

Alarm (Signal)/Lockout Switch

Auxiliary SwitchThe auxiliary switch provides circuit breaker contact status information by monitoring the position of the molded crossbar containing the moving contact arms. The auxiliary switch is used for remote signaling and interlocking purposes, and consists of one or two SPDT switches assembled to a plug-in module mounted in retaining slots in the top of the trip unit. Each SPDT switch has one “a” and one “b” contact. When the circuit breaker contacts are open, the ”a“ contact is open and the “b” contact is closed.

Auxiliary Switch

Shunt TripThe shunt trip provides remote controlled tripping of the circuit breaker. The shunt trip consists of an intermittent rated solenoid with a tripping plunger and a cutoff switch assembled to a plug-in module. When required for ground fault protection applications, certain AC rated shunt trips are suitable for operation at 55% of rated voltage.

Available in most AC and DC voltages.

Note: Approximate unlatching time—6 milliseconds. Approximate total circuit breaker contact opening time—18 milliseconds. Endurance—4000 electrical operations plus 1000 mechanical operations. Supply voltages suitable for use with Class 1 GFP devices. Marking label included with accessory kits.

Low Energy Shunt TripLow energy shunt trip devices are designed to operate from low energy output signals from dedicated current sensors typically applied in ground fault protection schemes. However, with a proper control voltage source, they may be applied in place of conventional trip devices for special applications. Flux paths surrounding permanent magnets used in the shunt trip assembly hold a charged spring poised in readiness to operate the circuit breaker trip mechanism. When a 100 microfarad capacitor charged to 28 Vdc is discharged through the shunt trip coil, the resultant flux opposes the permanent magnet flux field, which releases the stored energy in the spring to trip the circuit breaker. As the circuit breaker resets, the reset arm is actuated by the circuit breaker handle, resetting the shunt trip. The plug-in module is mounted in retaining slots in the top of the trip unit. Coil is intermittent-rated only. Cutoff provisions required in control circuit.

Low Energy Shunt Trip

Undervoltage Release Mechanism The undervoltage release mechanism monitors a voltage (typically a line voltage) and trips the circuit breaker when the voltage falls to between 70 and 35% of the solenoid coil rating.

Note: Undervoltage release mechanism accessories are not designed for, and should not be used as, circuit interlocks.

The undervoltage release mechanism consists of a continuous rated solenoid with a plunger and tripping lever assembled to a plug-in module.

The tab on the tripping lever resets the undervoltage release mechanism when normal voltage has been restored and the circuit breaker handle is moved to the reset (OFF) position.

With no voltage applied to the under-voltage release mechanism, the circuit breaker contacts will not touch when a closing operation is attempted.

Undervoltage Release Mechanism

External AccessoriesNote: For a complete listing of available external accessories, see Volume 4—Circuit Protection Catalog, CA08100005E, Section 25.

Non-Padlockable Handle BlockThe nonlockable handle block secures the circuit breaker handle in either the ON or OFF position. (Trip-free operation allows the circuit breaker to trip when the handle block holds the circuit breaker handle in the ON position.) The device is positioned over the circuit breaker handle and secured by a set-screw to deter accidental operation of the circuit breaker handle. (Field installation only.)

Non-Padlockable Handle Block

Padlockable Handle Lock HaspThe padlockable handle lock hasp allows the handle to be locked in the ON or OFF position. (Trip-free operation allows the circuit breaker to trip when the handle lock holds the circuit breaker handle in the ON position.) The hasp mounts on the circuit breaker cover within the trimline. The cover is predrilled on both sides of the operating handle so that the hasp can be mounted on either side of the handle. The hasp will accommodate up to three padlocks with 1/4-inch(6.4 mm) shackles. One per circuit breaker. (Field installation only.)

Padlockable Handle Lock Hasp

Key Interlock Kit (Lock Not Included)The key interlock is used to externally lock the circuit breaker handle in the OFF position. When the key interlock is locked, an extended deadbolt blocks movement of the circuit breaker handle. Uniquely coded keys are removable only with the deadbolt extended. Each coded key controls a group of circuit breakers for a given specific customer installation.

The key interlock assembly consists of a mounting kit and a purchaser supplied deadbolt lock. The mounting kit comprises a mounting plate, which is secured to the circuit breaker cover in either the left- or right-pole position; key interlock mounting hardware; and a wire seal. Specific mounting kits are required for individual key interlock types. (Field installation only.)

Key Interlock Kit

Padlockable Handle BlockThe device is positioned in the cover opening to prevent handle movement. Will accommodate one 5/16-inch (8.0 mm) padlock.

Eaton’s SPD Series for integration into electrical distribution equipment

EATON CORPORATION www.eaton.com

IntroductionEaton’s SPD Series surge protective devices

Eaton’s SPD Series surge protective devices are the latest and most advanced UL� 1449 3rd Edition certified surge protectors. Units are available integrated within Eaton electrical assemblies, including panelboards, switchboards, motor control centers, switchgear, and bus plugs. Side-mount versions of the SPD Series are also available for installation external to an electrical assembly. Application of SPD Series units throughout a facility will ensure that equipment is protected with the safest and most reliable surge protective devices available.

SPD Series units are available in all common voltages and configurations and also in a variety of surge current capacity ratings from 50 through 400 kA. Three feature package options are also available to choose from. The breadth of the SPD Series’ features, options, and configurations ensures that the correct unit is available for all electrical applications, including service entrances, distribution switchboards, panelboards, and point-of-use applications.

ApplicationsThe SPD Series is available as an integrated device within the following Eaton electrical assemblies:

• Panelboards• Switchboards• Motor control centers• Switchgear• Automatic transfer switches• Bus plugs

Remote display mounting optionThe SPD Series offers the option of mounting its display remotely from the device. This is useful for applications where OEMs or other integrators would like to embed the unit within a piece of equipment and still be able to view its display.

SPD Series unit catalog numbers ending with ‘B’ (refer to catalog number configuration on Page 7) should be ordered for applications where the display is to be mounted remotely. These units include the SPD Series unit and the remote display panel.

In addition to the unit itself, a remote display cable will have to be purchased. Remote display cables are available in 4, 8, and 12 foot lengths.

ote: N Integrated units factory-installed with Eaton switchgear assemblies do not require the purchase of a remote display cable. The cable is provided and all required mounting is performed at the factory.

Existing SPD Series units previously installed without a remote display also have the capability of mounting their displays remotely from the device. Complete remote display kits are available that contain all items required to mount the display remotely, including the remote display cable. Remote display kits are available in 4, 8, and 12 foot cable length options.

Molded-Case Circuit BreakersGeneral Description—Trip Units

006

Electronic RMS Trip Unit

GeneralEaton offers the most comprehensive range of electronic trip units in the industry for molded-case circuit breakers. All electronic trip units are rms sensing and can be applied from 70 A up through 2500 A. Eaton offers elec-tronic trip units as standard for circuit breakers rated above 800 A, and offers electronic trip units as optional for cir-cuit breakers 70 A up through 800 A.

Digitrip electronic trip units are AC devices that employ microprocessor-based technology that provides a true rms current sensing means for proper correlation with thermal characteristics of conductors and equipment. The primary function of the Digitrip electronic trip unit is to provide circuit protection. This is achieved by analyzing the secondary current signals received from the circuit breaker current sensors and initiating trip signals to the circuit breaker shunt trip when pre-set current levels and time delay settings are exceeded. All Eaton electronic trip units use a high effective sampling rate to maintain measurement accuracy, monitoring, and protection with nonlinear loads having harmonic content up to the 27th order.

Electronic trip units are applied to distribution systems when high stan-dards of protection and coordination are called for. In addition, electronic trip units can provide further enhanced features such as alarming, diagnostics, system monitoring and communications.

Eaton RMS sensing trip units fall into two main categories:

■ Front adjustable trip units (Digitrip™ RMS 310, 310+, 510, 610, 810 and 910)

■ Programmable trip units (Digitrip OPTIM™ 550 and 1050)

Front-Adjustable Trip UnitsFront-adjustable trip units are electronic trip units that have up to nine time-current setting options that are set by switches mounted on the front of the trip unit. The application for front adjustable trip units would be distribution systems that can be coordinated within the range of settings available and that do not require sophisticated coordination strategies to be applied down through the distribution system to small rated breakers.

Programmable Trip Units (OPTIM)Programmable trip units are electronic trip units that have up to 10 time-current setting options that are programmed electronically by the use of a programming device. The application for programmable trip units would be high integrity distribution systems that require superior levels of system coordination coupled with system alarming, diagnostics and monitoring.

Rating PlugsRating plugs provide a means to establish the breaker’s continuous current rating. Rating plugs are color-coded and interchangeable to make it easy to match the correct rating plug with the correct trip unit. The same rating plug can be applied to both 50 and 60 Hz distribution systems. Some rating plugs are fixed and some have an adjustable range of amperage values for greater flexibility. Digitrip 310, 510, 610, 810 and 910 trip units can be supplied with either a fixed or adjustable rating plug. Digitrip 310+ trip units are equipped with adjustable rating plugs. OPTIM style trip units are furnished with fixed rating plugs but have a programmable Long Time Pickup rating to allow application over a range of amperage values.

Cause of Trip IndicationAll OPTIM and Digitrip 510, 610, 810 and 910 trip units include Cause-of-Trip indication LEDs. Breakers using the RMS 310+ electronic trip unit have the ability to output cause-of-trip information through the test port. The Cause-of-Trip LED module provides trip information via LED indication. The Digiview and Panelmount Digiview can be installed in the RMS 310+ test port to provide both cause-of-trip information and phase current through an LCD display.

Additional Protection Features

Discriminator/Making Current ReleaseEaton’s Digitrip RMS electronic trip units are designed and built with safety and reliability in mind, both to protect the user and the equipment, as well as to make sure the trip functions within its design parameters. By providing a discriminator circuit to Digitrip RMS 510, 610, 810 and 910 trip units, as well as to Digitrip OPTIM 550 and 1050 trip units that do not have an instantaneous setting, the user is protected should a faulted circuit exist. The discriminator (or making current releases as it is often called) is set at 11 times the rating plug ampere rating and is enabled for approximately the first 10 cycles of current flow. Should a fault condition exist, the breaker will trip with no intentional time delay on closing, protecting the user from a potentially unsafe condition.

Instantaneous OverrideIn addition to a discriminator, an instantaneous override is present in all molded-case and insulated-case circuit breakers to provide additional protection for the breaker. The instantaneous override is factory set nominally just below the breaker withstand rating.

Trip Unit OvertemperatureDigitrip electronic trip units can operate reliably in ambient temperatures that range from –20 °C to +85 °C. In the unlikely event that temperatures exceed this ambient, the trip unit has a built-in overtemperature trip to protect the trip unit should the temperature exceed these design parameters.

Thermal MemoryDigitrip RMS and Digitrip OPTIM electronic trip units incorporate powered thermal memory, i.e., the units remember recent overcurrent events that may have initiated the trip timing sequence, and then returned to nominal levels, halting the sequence prior to trip initiation. In the event that the current levels again exceed the pickup set point within a few cycles of the original pickup, the unit’s memory recalls the previous near trip and automatically imposes a shorter delay time. In effect, the unit treats multiple time-related events as a single continuous event thereby preventing system damage due to cumulative overheating.

As a further enhancement, the trip units incorporate an unpowered thermal memory feature. In the event that current levels cause the breaker to trip and the breaker is immediately reclosed, the trip unit remembers the previous overcurrent trip and again

imposes a shorter delay time should an additional overcurrent occur before a sufficient cooldown period has elapsed.

Thermal memory protects the distribution system from cumulative overheating caused by repeated over-current conditions. OPTIM trip units allow this to be turned ON or OFF.

System AlarmsDigitrip RMS 610, 810 and 910 electronic trip units incorporate a high load alarm capability. Set at 85% of Ir, the alarm will be initiated once the load current exceeds 85% for 40 seconds. Once this occurs, the HILD message will flash in the display window and the power/relay module will operate to send a remote signal.

Digitrip OPTIM electronic trip units also offer a high load alarm capability but with more flexibility. OPTIM trip units have a high load alarm that can be programmed to operate between 50% and 100% of Ir.

Digitrip OPTIM electronic trip units incorporate a ground fault alarm capability. Settings available for ground fault alarm are the same as for ground fault trip. Once a ground fault alarm occurs, both local and remote signalindication is available (OPTIM 550 is remote only).

System DiagnosticsWhenever a circuit breaker trips, it is normally imperative that the cause of trip be determined quickly, the faulty conditions rectified, and the breaker put back into service. Digitrip RMS 510, 610, 810 and 910, and Digitrip OPTIM electronic trip units incorporate a complete package of systems diagnostics to meet this challenge.

Four cause-of-trip LEDs are embedded in the front of the trip unit case, indicating that the cause-of-trip was either a long delay, short delay, instantaneous or ground fault. Remote signal indication for cause of trip as well as magnitude of trip information is also available.

Breakers using the RMS 310+ electronic trip unit have the ability to output cause-of-trip information through the test port. The Cause-of-Trip LED module provides trip information via LED indication. The Digiview and Panelmount Digiview can be installed to provide both cause-of-trip information and phase current through an LCD display.

Systems MonitoringDigitrip RMS and Digitrip OPTIM electronic trip units offer a complete menu of monitoring capability to include current, power and energy, power factor, power quality harmonics, and other related parameters with a high level of accuracy.

Digital DisplayDigitrip RMS 610, 810 and 910 have a large, easy-to-read four-digit alpha-numeric display mounted on the trip unit. The display is supported by LEDs that indicate which parameter is being displayed along with the unit the value is displayed in, e.g., kA and so on.

Current MonitoringDigitrip RMS 610, 810 and 910 trip units are capable of monitoring currents in individual phases (A, B, C) as well as ground currents. Digitrip OPTIM 550 and 1050 trip units are capable of monitoring currents in individual phases (A, B, C) as well as neutral and ground currents.

Values are displayed in the digital display window in kA. Accuracy of the current monitored values is ±2% of full scale sensor rating.

Breakers using the Digitrip 310+ electronic trip unit have the ability to output phase current monitoring information through the test port. The Digiview or Panelmount Digiview can be installed to provide phase current through an LCD display.

For current and voltage monitoring with 0.5% accuracy of reading that can be used with thermal-magnetic or electronic trip units, refer to the Power Monitoring/Metering Module (PM3) on Page 27.4-41.

Power and Energy MonitoringFor the trip unit to calculate true power and energy values, a Potential Transformer Module (PTM) is required. This PTM is mounted internally(R-Frame and larger) or externally (N-Frame or smaller) to the breaker, and provides voltage to the trip unit.

Digitrip RMS 810 and 910 trip units are capable of monitoring peak power demand, present power demand, and reverse power flow in MW. Addition-ally, both forward and reverse energy consumption in MWh can be moni-tored. Digitrip OPTIM 1050 trip units can also monitor the same power and energy parameters, but the units are displayed in kW and kWh.

The accuracy of power monitored values is ±4% of full scale sensor/frame rating.

The accuracy of energy monitored values is ±5% of full scale sensor/frame rating.

Both the RMS 910 and OPTIM 1050 report power factor. Digitrip RMS 910 trip units have the additional capability of monitoring line-to-line voltage.

For Real Power and Reactive Power monitoring with ANSI C12.1 revenue class accuracy that can be used with thermal-magnetic or electronic trip units, refer to the Power Monitoring/Metering Module (PM3) on Page 27.4-41.

Harmonics MonitoringDigitrip RMS 910 and Digitrip OPTIM 1050 trip units are capable of monitor-ing values of current harmonics. Percentage of total harmonic content can be monitored for each level of harmonic content up to the 27th harmonic. Additionally, a total harmonic distortion (THD) value can be calculated and displayed providing the user with total system current harmonic monitoring capability.

Curve Shaping Eaton Digitrip RMS 310 trip units are available with up to five phase and ground adjustments on the front of the trip unit. Digitrip RMS 310+ trip units are available with up to six phase and ground adjustments on the front of the trip unit. Selective system coordination with both upstream and downstream devices can be achieved to provide an economic solution for less sophisticated distribution systems.

For more sophisticated selective coordination systems Digitrip RMS 510, 610, 810 and 910 trip units are available with up to nine curve shaping choices via switches on the front of the unit. Curve shaping flexibility is provided by dependent long and short delay adjustments that are based on continuous amperes (Ir) selection.

Digitrip OPTIM 550 and 1050 trip units offer programmable curve shaping via 10 curve shaping choices that are programmed electronically into the trip unit. OPTIM also offers virtual infinite settings to allow the user to optimize coordination for a selectively coordinated distribution system. In addition, time-current set points can be downloaded via a communication system from a central personal computer. Digitrip OPTIM is normally applied to systems where system integrity is very important.

Zone Selective InterlockingZone selective interlocking capabilities are available with Digitrip RMS 310+510, 610, 810 and 910 trip units as well as Digitrip OPTIM 550 and 1050 trip units.

Note: Optional accessory on the OPTIM 550.

Zone selective interlocking provides increased system protection and can reduce arc flash risk by allowing the breaker closest to the fault to trip without any preset time delays. This is achieved by setting up the distribution system as shown in Figure 27.1-2. The hardwired connection between the trip units sends a restraining signal upstream, allowing the breaker closest to the fault to act instantaneously. Zone selective interlocking reduces stress on the distribution system and can reduce arc flash risk by isolating faults without time delays.

Figure 27.1-2. Zone Selective Interlocking

Fault 1There are no interlocking signals. The main breaker trip unit will initiate the trip instantaneously.

Fault 2The feeder breaker trip unit will initiate the trip instantaneously to clear the fault; and Zone 2 will send an interlock-ing signal to the Zone 1 trip unit. The Zone 1 trip unit will begin to time out, and in the event that the feeder breaker in Zone 2 would not clear the fault, the main breaker in Zone 1 will clear the fault in 0.5 seconds.

Fault 3The branch breaker trip unit will initiate the trip instantaneously to clear the fault; and Zone 3 will send an interlock-ing signal to the Zone 2 trip unit; and Zone 2 will send an interlocking signal to Zone 1.

Zone 1 and Zone 2 trip units will begin to time out, and in the event that the branch breaker in Zone 3 would not clear the fault, the feeder breaker in Zone 2 will clear the fault in 0.3 seconds. Similarly, in the event that the feeder breaker in Zone 2 would not clear the fault, the main breaker in Zone 1 will clear the fault in 0.5 seconds.

Eaton DOE 2016 efficient distribution transformers

DOE 2016 efficiency guidelinesThe U.S. Department of Energy (DOE) is tasked with periodically reviewing energy efficiency requirements of many appliances, including distribution transformers. The latest DOE ruling, originally published on April 18, 2013, mandates new, higher, energy efficiency levels for liquid-filled and dry-type distribution transformers. This new ruling, 10 CFR Part 431, commonly referred to as DOE 2016, requires that distribution transformers manufactured starting on January 1, 2016 that are intended for sale or installation in the U.S. and U.S. Territories meet the new minimum efficiency levels.

Eaton is proud to support this new legislation that will have long-lasting positive environmental benefits lasting for decades into the future.

For low-voltage dry-type distribution transformers, the new minimum energy efficiency levels, required effective January 1, 2016 are:

EATON www.eaton.com

General construction features of DOE 2016 efficient transformers rated 600 V and belowGeneral description

Eaton’s single-phase and three-phase general purpose dry-type ventilated transformers are of the two-winding type, self-cooled, and are available in a variety of primary and secondary voltage combinations.

Eaton’s transformers are designed, manufactured, and tested in accordance with all of the latest applicable ANSI, NEMA, and IEEET standards. All 600 V class ventilated transformers with ratings through 1500 kVA are UL listed and bear the UL label. Open core and coil assemblies are UL recognized (UR) labeled products.

These transformers are designed for continuous operation at rated kVA for 24 hours a day, 365 days a year, with a normal life expectancy as defined in ANSI C57.96.

Efficiency validation

Eaton-manufactured transformers in compliance with 10 CFR Part 431 (2016), “DOE 2016 efficient” bear the UL Energy Efficiency Verification Mark to confirm that the transformer meets the minimum energy efficiency requirements set forth in federal law 10 CFR Part 431.

Insulation system

The design life of transformers having different insulation systems is the same; the lower temperature systems are designed to have the same life as the higher rated temperature systems.

Most Eaton ventilated transformers, regardless of their temperature rise, are manufactured using a 220 °C insulation system. Required performance is obtained without exceeding the insulation system rating at rated temperature rise in a 40 °C maximum ambient, with an average of 30 °C over a 24-hour period. Transformers manufactured with 220 °C insulation system meet the requirements of NEC 450.21(b) Exception No. 2. It is not necessary to install them in a special, fire-resistant room.

All insulation materials used are flame-retardant and do not support combustion, as defined in ASTM Standard Test Method D635.

Core and coil assemblies

The transformer core is constructed using high-grade, non-aging, silicon steel with high magnetic permeability, and low hysteresis and eddy current losses. Maximum magnetic flux densities are substantially below the saturation point. The transformer core volume allows for efficient transformer operation at 10% above the nominal tap voltage. The core laminations are tightly clamped and compressed. The BIL (basic impulse level) for all 600 V-class windings is 10 kV. The core and coil assembly is installed on neoprene vibration-absorbing pads. Coils are treated with a varnish that does not support the growth of fungus.

Ventilated transformers with wye-connected secondaries have the neutral brought out to a separate terminal or busbar.

The core and coil assembly is grounded to the transformer enclosure by means of a flexible copper ground strap. The copper ground strap is sized per the NEC to be a grounding conductor.

Eaton three-phase DOE 2016 efficient transformers are provided with a bonding ground bar attached to the bottom panel for compliance with NEC 450.10(A).

Electrostatic shielding

There are no industry standards for electrostatic shield performance. Eaton-manufactured transformers have been tested by an independent laboratory to meet the following attenuation levels:

When tested per MIL-Std-220A, Method Of Insertion Loss Measurement, with matched impedance no load technique:• Common mode noise attenuation:

Minus 80 dBA minimum at 0.1 kHz to 1.5 kHz; minus 55 dBA minimum at 1.51 kHz to 100 kHz

• Normal mode (transverse mode) noise attenuation: Minus 30 dBA minimum at 1.5 kHz to 10 kHz.

Primary to secondary capacitance of 24.74 to 18.06 picofarads over the range 100 to 20 kHz.

Taps

Primary taps are available on most Eaton ventilated transformers to allow compensation for source voltage variations.

Winding terminations

Primary and secondary windings are terminated in the wiring compartment. Ventilated transformers have leads brought out to aluminum or copper pads that are pre-drilled to accept Al/Cu lugs. Aluminum-wound transformers have aluminum pads; copper-wound transformers have copper pads. Lugs are not supplied with Eaton transformers; however, lug kits are available as a field-installed accessory. Eaton recommends external cables be rated 75 °C for ventilated designs.

Enclosures

The transformer enclosure is made of heavy-gauge steel and is finished using a continuous process of degreasing, cleaning, and phosphatizing, followed by electrostatic deposition of a thermosetting polyester powder coating and subsequent baking. The coating color is ANSI 61 grey and is UL-recognized for indoor or outdoor use. In compliance with NEMA ST-20, Eaton’s ventilated transformers are designed such that the maximum temperature on the top of the enclosure does not exceed 50 °C rise above the ambient temperature.

For ventilated transformers, the enclosure standard construction is drip-proof, NEMA 2, with lifting provisions on the top of the core. All ventilation openings are protected against falling dirt. Proper installation of weathershields makes the enclosure NEMA 3R rated and suitable for outdoor use.

To ensure proper ventilation and cooling of the transformer, follow manufacturer’s recommended clearance around ventilation openings.

Installation clearances

Eaton’s transformers should be installed with a minimum clearance around the transformer enclosure to prevent accidental contact with flammable or combustible materials.

EATON www.eaton.com

Eaton 2016 efficient transformer is UL approved to be installed 2 inches away from walls or obstructions. The industry minimum clearance is 6 inches. Eaton transformers will reduce your total installation depth by a minimum of 4 inches.

Eaton voluntarily asked UL to verify the DOE 2016 efficient transformers’ efficiencies. Customers can rely on Eaton transformers to meet their required efficiency.

Reduced shipping damage risk by bottom mounting core-coils and reinforced enclosure bottom.

Includes bonding ground bar as standard in compliance with NEC 450.10 (A).

Increased wiring compartment.

OSHPD California seismic certified all floor mounted frames and up to 150 kVA wall mounted.

Eaton increased the 2016 transformer’s bottom-to-floor clearance to a minimum of 4 inches, and changed the mounting feet to face outward. These changes provide ease of conveyance once the pallet has been removed and ease of installation.

Eaton voluntarily asked UL to verify the DOE 2016 efficient transformers’ efficiencies. Customers can rely on Eaton transformers to meet their required efficiency.
