Targets one-class higher performance, in realizing superb breaking performance
The WS Series presents a new technology.
[PA Auto-Puffer]Polymer Ablation type Auto-Puffer [Adopted on SGW,
HGW, RGW, UGW ]PA auto-Puffer is the technology to increase the interrupting performance by blowing out the gas to the arc by right angle. The gas pressure which is generated from high-polymer materials is accumulated in the accumulating space, and the gas is blown to the arc to extinguish. Especially this technology improves the high voltage breaking performance.
[JPT]Jet Pressure Trip Mechanism [Adopted on SGW,
HGW, RGW, UGW ]Ablation gas jet through the hole installed on the unit case directly activates the trip mechanism. This acts faster than the relay (magnet), and contributes to improved current-limiting performance and breaking reliability.
• Interchangeable Relay-unit Thermal type Electronic type • AC/DC common use • Thermal adjustable range is expanded.
Ablation Gas accumulating Gas flow Arc extinguishing
Arc Extinguishing Concept
Tripping actuator to push the trip-bar before the trip by relay unit.
Trip Bar
When short circuit fault occurs, the contacts are opened and arc is generated between the contacts.At that time the pressure in the unit case become very high.

During revolution the movable contact is constantly in contact with the holder, maintaining current flow.
Further evolution in Mitsubishi original ISTAC breaking technology*. Optimization of the current path and the added magnetic core enhance driving electromagnetic forces. By the high-speed opening and the arc driving, the rising rate of arc voltage is increased and the peak current “lp” is decreased.
*The triple forces which are the repulsive force, the attractive force, and the pressure accelerate the separating speed of the movable conductor.
(1) Electromagnetic attractive force between Current A and Current C(2) Electromagnetic repulsive force between Current B and Current C(3) Ablation gas pressure
These three forces generated high-speed drive
[Shunt-less]Shunt-less Current Flow Technology [Adopted on SGW,
HGW, RGW, UGW ]Double plates conductors hold the movable conductor without flexible wires. This shunt-less structure achieves the extending operating cycles.

Notes: (1) The clasps are not supplied standardly, and should be prepared by users Details on dimensions and others will be available upon request. (2) When the optional clasp is used. (3) The tolerance from the center of ø62 is shown. (4) The dimensions of the front-face type are shown. Some of the back-face and plug-in types have a different reference plane for mounting the circuit breaker. (5) The front plate drilling dimensions for the U series differ from those shown above. Please consult us for their details.
Notes: *1. Retainers are not included. They must be provided by the customer.*2. When using optional retainer.*3. Shows the tolerance for the distance from the center of a 62mm dia. hole.*4. The figures show the front-connection dimensions. Some rear-connection and plug-in breakers have a different reference surface for mounting purposes.*5. S4CP and S4SP are for isolation purposes. (Specify OFF lock only.) The tolerance is less than 5mm. It does not conform to isolation purposes, however, if the deviation is more than 2mm.
Remark: The clamp for surface plate interlock fastener is common to 2P, 3P and 4P.
● The handle can be locked at either ON or OFF position. (Three padlocks (40mm) can be installed. Off-position lock only specifications are also acceptable.)
● Digrees of protection (IEC60529) IP5X
● Indicates the tripping of the breaker even in ON-lock position--but only in cases when a single padlock(35mm) is used.
● Degrees of protection (in accordance with IEC60529): IP5X.
Remark: (1) Trip action can be displayed when the circuitbreaker trips even if ON-position lock is selected(only in the case of a single padlock (35 mm)).

General precautions for motor-operated electrical MCCBs● Motor-operated types have intermittent ratings, and therefore they
should not be operated more than 10 times consecutively (one on/off counts as an operation).
● The operating voltage should be between 85~110% of the rated control voltage.
● When the breaker is tripped by trip button or breakdown (i.e., overload or short circuit), the breaker will not show that it has been tripped (except for motor-operated type 1 breakers).
● The dielectric strength of the electrical operating circuits is 1500V. When performing a dielectric strength test simultaneously with another device at a voltage over 1500V, the operating circuit terminal should be disconnected.
Automatic Reset● If the breaker is an auto reset type, it contains a built-in alarm
switch and the off-control circuit closes when the breaker is tripped. Since the breaker automatically resets itself after tripping, the power is easily restored by switching on the breaker again. With a UVT mounted, however, auto reset may not be possible. In this case, please consult your dealer.
Motor-operated type (2)● Electrical operation Forward and reverse motor rotation is changed by ball screw to
switch the breaker ON and OFF (reset).● Manual operation The manual operation handle can be used to switch the breaker ON
and OFF directly.● Cautions during electrical operation1. In case the UVT operates and a circuit breaker trips if the breaker
has a UVT, the re-closing procedure may differ according to the state of the breaker before tripping.When the circuit breaker trips while turned ON..... Reset (OFF) -> Turn ONWhen the circuit breaker trips while turned OFF..... Turn ON (idle tripping) -> Reset (OFF) -> Turn ON (If it fails to turn ON (idle tripping), please operate Reset (OFF) and turn ON.)
2. Do not send ON and OFF signals consecutively. An interval of at least 0.5s is required between each ON and OFF.
3. For models with auto reset capability, resetting after an NFB trip should be performed after an interval of 0.5s.
4. The electrical operating device is equipped with a pumping prevention circuit. Although it is possible to set the device to OFF while it is set to ON, it is impossible to return it to ON immediately. To return to ON, first shut off the ON switch, then set it back to ON.
5. Special care is required during electrical operation because the manual operation handle moves at high speed. Also be sure to turn off the circuit power supply when using manual operation.
6. With manual operation, ensure that the handle is fully extended.

Control circuitThe dotted line shows an additional connection for the automatic-reset type.
Spring-charged type● Electrical operation When the ON switch is closed, the coil is excited to release the
latch mechanism and the force of the closing spring turns the breaker ON instantly.
When the OFF switch is closed, a relay starts the motor which turns the breaker OFF and charges the spring simultaneously.
● Manual operation Pressing the ON button will release the latch mechanism and the
force of the closing spring turns the breaker ON instantly. Pressing the leaf spring, pulling out the manual handle and pumping
it back and forth over 10 times will turn the breaker OFF and charge the spring at the same time.
● Cautions during electrical operation Whenever an electrical operation device is to be installed in or
removed from the breaker, the breaker must be tripped and the device discharged.
Pushing the TRIP button on an MCCB with an electrical-operation device installed will not trip the breaker in the OFF state. This does not mean the breaker is faulty.
Switching OFF a breaker with an electrical-operation device installed will take 3s. If instant opening is required, install an SHT or UVT to the breaker.
● The breaker contains a built-in pumping-prevention relay.
