■Incandescent Lamps
Applicationfor Lightingloads
For Lighting loads, electrical endurance or the number ofswitching can be short/small except some special cases.Therefore, the selection points are, ① The total of the input current to the loads should not
exceed the rated current of the magnetic contactor. ② Inrush current by starting should remain below the open
circuit current capacity of the magnetic contactor.
Because the filament of an incandescent lamp is lowespecially at ambient temperature, theoretically the inrushcurrent at the moment of lighting the lamp is 3 to 16 times ofthe rated current, but the impedance of the circuit and theself-heating of the lamp limit the inrush current to 7 to 10times of the rated current in practical conditions. The exampleof characteristics from the moment of lighting the lamp to thepoint being stable current is shown in the graph in the right.The magnetic contactor applied for incandescent lamps shouldbe selected with a transient current of this level taken intoconsideration, and the rated current to the incandescent lampsshould be the same as or lower than the AC3 rated current.
■Fluorescent Lamps
A fluorescent lamp is the combination of a lamp and a ballast, and depending on the type of the starting method of theballast, it can be classified into a starter or a quick starter. The starter method turns on the lamp by use of a manualswitch or an automatic switch such as a glow lamp, widely used for households. On the other hand, the rapid startermethod turns on the lamp immediately after the switch is turned on without the use of a mechanical contact, generallyapplied for buildings, factories, hospitals and schools. The starting current of a fluorescent lamp varies depending on theballast circuit and whether or not the power factor adjustment capacitor exists in the circuit. In any case, as the startingcurrent is about 10 times of the normal operating current, so it is recommended to select the magnetic contactor so thatits capacity is the same as lower than AC3 operating current.

■Number of general type mercury lamps that can be switched
■Mercury LampsA mercury lamp is the combination of a mercury lamp and a ballast, and thestarting characteristics of a mercury lamp vary depending on the type of theballast. The types of ballasts are the general type (low P.F. type and high P.F.type), the fixed power type and the low starting current type and the respectivestarting characteristics are shown in the graph in the right. For the generaltype and the low starting current type, a starting current of 1.2 to 1.8 times ofthe rated current flows through the ballast for the first few minutes. Besides,the starting current of the fixed power type is lower than the ballast. The highP.F. type is inserted in a power factor adjustment capacitor in parallel with thepower source, which causes an inrush current at the moment of starting.When a magnetic contactor is used, the point of consideration is the durabilityof the magnetic contactor against over current. However, our magneticcontactors are capable of withstanding the over current of 1.2 to 1.8 times ofthe rated current for some minutes without a problem. Therefore theselection of the magnetic contactor is recommended so that the input currentof the ballast is within the AC3 input current.

Structure andOperation
■Structure
Open stateWhen the two contactors are in the “OFF” position, thelever maintains its “OPEN” state by reboundingsprings.EnergizingWhen an any one of the contactors is energized, as thelever pin comes down by the crossbar, the interlocklever revolves around its axis of rotation and theheads of levers are interlocked. Although anothercontactor is energized at this moment, it is prohibitedbecause the heads of levers are interlocked.ReleasingIf one of the two contactors is de-energized, crossbarcomes up by the power of kickout spring of thecontactor, and then interlock lever goes up by thecross bar, and added with the power of reboundingsprings, the interlock lever gets pushed up to the openposition.HandlingThe electrical interlock should be commonlyconnected to the “b” contacts of the two contactors.Do not install horizontally.

■Operational Environment
1) Ambient Temperature : Reference temperature20℃~40℃, the daily average temperature for 24 hours should not exceed 35℃
2) Maximum temperature in the panel : 55℃(Enclosed type: 40℃)
3) Relative Humidity : 45~85% RH4) Altitude : Less than 2,000m5) Vibration resistance : 10~55Hz 2g6) Impact resistance : 5g7) Storage Temperature : -30℃~65℃ in no frozen place
■Mounting
1) Install the contactor at a dry location with the minimum vibration.
2) In case of transverse or horizontal mounting, reduction of life span and deterioration of various performance may take place compared with standard mounting.
3) Reversed mounting may cause noise from the contactor.

■Direct connection to a magnetic contactor
The main circuit and the operation part are separately designed and the operation partis commonly designed for TH 22, 40, 85, 100, 150 for improving safety.
■Separation of power/operation part
Separate temperature compensation with the ambient temperature change is not necessary(Applied ambient temperature: -10°C ~ +40°C).
■Temperature compensation Bi-metal applied
In case of mounting the overload relays independently, the separate mounting kits areavailable for panel installation with rail or screw (Applied types: TH 22, 40, 85)
■Separate mounting unit
■Ratings of Auxiliary Contact
■Strong operation part with Vibration Resistance (700g)
Finger proof cover can be installed for electric conduction parts not to be connectedto human body. *Finger proof cover is an option.
■Finger proof cover can be installed.
3 steps current settingThe rated current can be set with a Philips or flat head screw driver.Easy in setting Manual-Auto ResetFor the increased convenience of the user, you can select manual reset or automatic reset at your choice.(Manual Reset)As shown on the right, turn the reset screw so that the arrow mark points to “H” and allow the screw to lift up.(Automatic Reset)Push down the reset screw and turn it so that the arrow mark points to “A”.
Trip IndicationIf the TOR is tripped, it descends 2~3mm and indicates the trippedcondition. When testing manually, lift up the transparent cover and push(Transparent cover is to protect the careless adjustment after settingthe contact current by knob).

Characteristics
■Phase Loss protection types that are the most suitable ones for the protection of motors from burnouts by overload and phase loss.
Our Overload Relays (TK Series) firmly protect motors from the burnouts caused by overload and also, phase lossoperation of various kinds of motors by introducing our unique ADL (Amplified Differential Lever) Mechanism.
■Ratings and External Dimensions
Same as Standard Overload Relays
■ADL(Amplified Differential Lever) device
In case of phase loss, release lever rotates by differentiation between Shifter A and B, so relay contacts are open earlier than normal overload.
■No Load
All three bimetals are in the Start positions that are not bent.
■Rated Load
Three bimetals are bent for size ‘a’and Shifter A, B, Release lever moves right in parallel, but contacts are not yet released.
■Overload
Due to over current, bimetals are bent for size’b’ in comparison with the rated load, so that they releasecontacts.
■Phase Loss (R-phase)
S & T-phase bimetals are bent, while R-phase bimetal is not, so that release lever turns right by Shifter A centeringthe connecting point with Shifter B. In that case, themovement of the end of release lever is magnified into leverratio and contacts are open earlier than 3 phase overload.This will also applied to the case that S, T phases are lost.
■Protection from burnout caused by phase loss in 3 phase induction motor.
For protecting motor from burnout caused by phase loss,you need to know how the coil temperature of motor willbe. In case the input circuit of a 3 phase induction motor isin phase loss, the temperature rise for stator coil isreported as graph in the right. 13 as an example. Thegraph in Pic. 13 shows a comparison with the temperaturerise in 3 phase rated load. In this state, normal and phaseloss operation are same in coil current and different in coiltemperature. Therefore, thermal overload relay shouldoperate with lower current than it is used for normal 3phase over current protection because the phase lossprotection is done. Our phase loss protection thermaloverload relay is adopted a unique ADL Mechanism, so, inphase loss, it is a highly reliable relay with the reasonablephase loss protection operating with the lower currentthan it is used for overload protection.

When conductors contact, resistance is generated on the contacted parts and, if current flows on the parts, heat isgenerated. In case this kind of heat is increased abnormally, fire can occur due to the insulation breakdown by the burnoutof mold and the disorder in power source system can occur due to the short circuit between phases. It is to protect against them.
Temperature detection Module is classified as normal and advanced types.

Electronic Over Current Relays
■Phase Reversal and Phase Loss protection by Voltage detection <Pass-through type 3ESS>•Detect phase reversal and phase loss by voltage and operate in advance, so it protects load more securely.
■Without the external CT, it is available to use up to 120A.•Available in combining with all MCs that are less than 120A of rated current (Max. wire size is 38mm2).
■In Phase Loss, protecting it after O-TIME without experiencing D-TIME.•Our 3ESS type is a 2 CT type and a separate phase loss detection circuit is adopted, so that it protects phase loss
securely regardless of current setting.
■Troubleshooting for the malfunction due to noise and its cause of defect.•With the adoption of the high quality power circuit (licensed), it completely troubleshoots the malfunction due to
strong high frequency noise and its cause of defect, which have been the defects of previous products.
■Circuit Design basically increased in reliability by using verified parts only.•Designed with the widely-used IC which has been verified its stability for some decades, it completely removes the
cause of defects, while the usual electronic over current relays using the one-chip micom, MCU (Microprocessor
Control Unit) which is integrated several hundreds of thousands of semiconductors are to be weak to noise in structure.
■Highly convenient for installation and using•For the Contactor mounting types, it is more convenient to work with the design of the auxiliary terminal attachment.
DAERYUK’s products have achieved the certifications from the Certified
International Quality Management Authorities and we are supplying the
believable and precise products by ceaseless technological innovation.

■Operation Time setting
Operation Time is based on the scale of the timeadjustment dial.•Set the operation time adjustment dial considering
starting time of motor.•Operation time setting is possible in adjustment.
3ESS/SS3/SS: D-Time 0.2~60 sec, O-Time 0.2~12 sec.ES2 SP/ES: 0.2~12/0.2~30 sec.
■Rated Current Setting•Start the motor setting the current adjustment dial
at its maximum.•Turn the adjustment dial counterclockwise at the
operation state and then turn it clockwise slowly from the point where overload indication lamp(O.L) flickers and stop it at the point where the lamp is put out.
■Operation checking•If you push the TEST button at the state where only
operation power is applied, the over current indication lamp (O.L) of motor protection relay is on and it trips putting out the power lamp after the time set.•If you push the RESET button, the over current indication lamp is put out and the power
lamp is on returning to the initial state.

※ Under the Phase Loss, the current thatflows on the normal coil of motorincreases for 150% or more. Thiscurrent increase raises thetemperature of the coil and destroysthe insulation of the coil, so that itcauses burnout of motor. DPRoperates after the O-TIME set by theuser or within 4 sec. and protects theburnout of motor(load) by the types ofDPR.
※ The Min : Max Current Setting Ratio ismore than 1:10, so the protectingrange by one type is wide and it offersstrong protection function along witheasy inventory. One model consistingof 2 types or 3 types can protect theload from 0.1 to 600A.

When a motor starts up, starting current about 5 to 8 time of the rated operating current flows and starting time defers from load(motor) to load. D-TIME is the time during which starting current is not recognized as over current and activation of the DPR issuppressed. It is set by the D-TIME knob and only operates when a motor starts. The Relay which does not have the D-TIME knoband have a O-TIME knob only is set considering D-TIME and O-TIME.
If over current exceeding the present value flows continuously during operation, the time between the first detection of the overcurrent and the activation of the DPR is adjusted by use of the O-TIME knob.Upon detection of over current, the definite time type activates the DPR after the time set by the O-TIME knob has elapsed. While,the inverse time type activates the DPR according to the current-time characteristic curve selected by the O-TIME knob.
It is installed on the front face of the DPR for periodic check and test. While control voltage is normal, continuously pushing theTEST button trips the internal relay after D-TIME + O-TIME has elapsed. You can close the test session by pushing the reset button.
This is the function to restore the state of the DPR back to the condition it was activated.
•Manual Reset : Pushing the reset button on the front face of the DPR, it is initialized immediately.•Electrical Reset : This method initializes the DPR by cutting off the power source of the control voltage supplied to the DPR.
It is initialized by means of a remotely installed “off” button or reset switch.•Auto Reset : This is the automatically initialized function after set time. One is the model that the auto reset time can be set
by the user selecting the R-TIME knob or Mode S/W to auto and another is the model that the auto reset time is set when it is dispatched by order.

This is the fail-safe mode such that, upon application of the control power to L1 and L2 terminals, the internal circuit of the DPRpowers on normally and the internal relay is magnetized consisting the sequence normally, but upon the activation of the DPR by overcurrent, the internal relay gets demagnetized. Also called NVR (no voltage release) function, this is the standard mode for the DPRrecommended for perfect protection. The mode can be selected by order or the embedded DIP Switch(NVR) according to models.
This is for users to find the systematicproblem in the early stage by disabling thestarting of motor in case control voltage isnot applied to the DPR or there is aninternal defect or its life span has expired.

This is the non-fail-safe mode such that the internal relay initially remains demagnetized and so it is possible to drive the loadregardless of the conditions of the power to L1 and L2 terminals or the operation of the DPR, while the internal relay gets magnetizedupon activation of the DPR by over current.The mode can be selected by order or the embedded DIP Switch(NVR) according to models.

It takes periodic check since the DPR mayfail to protect the load if control voltage issupplied abnormally to the DPR or there isan internal defect or its life span hasexpired.
Cautions(Common)
Technical Information
•Control Power should be connected and supplied exactly to the control power terminal. If the connection to the output terminal iswrong, it may cause the burnout of DPR and short circuit of system. Wiring work after knowing the wiring diagram on the instruction or catalog thoroughly is highly recommended.
•When wiring, followings should be complied.-You should do the wiring exactly referring to the 3-line wiring diagram and connect the terminal and wire to keep enough contacts between them.
-When tightening bolts, you should use a electric screw driver which can keep the rated torque. When working manually, you shouldnot wear down screws by giving force too much at the last stage of tightening and should use a tool matched well with bolts.
•The CT attached in DPR is for the use of current detection to operate DPR, so it should not be used for other purpose. Also, you should not damage on the CT by giving force too much on the wires to penetrate them.
•An operator should check if the DPR is working properly as an protection relay by pushing Test button regularly in the field, so that the DPR is protecting motor soundly.
•When you carry or install DPRs, they should not be impacted severely and fallen. If this case happens, please check the function by Test button or contact our A/S Center.
•In the power systems with the frequency change equipment such as inverter, DPR may be affected by the harmonics generated from this equipment and various noises. In this kind of system, you should supply the control power through tow winding transformer as shown on the example wiring diagram.
•Please refer to the instruction for the A/S about the effective life of DPR.
•You need to choose and use DPRs according to the applied equipment’s characteristics by differentiating N-&R-types for the analogue circuit products.
•Environment and Cautions are as follows;-Temperature: Storage (-30~80°C), Operation (-20~60°C). Do not use beyond these ranges.-Humidity: 30~85% RH without due condensation. Do not use beyond this range.-In the place with much dust, the internal circuit may be weakened by that, so we recommend you to install and operate DPRs preventing dust from incoming and do the cleaning regularly.
Definition
Considerationsfor theselection ofappropriateDPR for theload protection
DPR is mainly used for the protection of motors in the industrial field. The thing which may be overlooked in selecting DPRs is howsimilar the types of heat characteristics curve of motor and DPR are.The heat characteristics curve of motor is based on the curves for coils used for rotor and stator, so it shows similar curve to thosefor coils. Also, the heat characteristics curves of various wires used in the industrial fields like various distribution panels includingMCC are usually showing similar curves to that of motor along with the wire connected to motor. Therefore, the relays havingsimilar operation characteristics to this feature should be used in the sequence using motors for the protection of wires and motors.The characteristics curves of MCCB usually used indistribution panels are also showing the similar curves tothose for motors, so, in terms of the protection assistanceamong the protection equipments, DPRs having thecharacteristics need to be used.The Definite Curve DPRs are mostly used for motorprotection because the time and current settings are easy tocontrol and the operation can be checked easily, but theInverse Curve DPRs are most suited for more secured motorprotection or the protection for high quality motors becausetheir curves are very similar to the heat characteristicscurves of motors.

Inverse Curve vs. Definite Curve
•Inverse Curve DPR: If the current flows with more than the setting value(appropriate current), the Trip Time of DPR differs by theover current value•Definite Curve DPR : If the current flows with more than the setting value(appropriate current), DPR operates and trips the circuit
after certain period of time (setting time) regardless of the over current value.

Classification ofDefinite & InverseCurve DPR byapplication
CharacteristicsCurves
Caution
•Definite Curve DPR : Loads almost having no change in the starting and operating currents•Inverse Curve DPR : Loads showing inverse curves in the heat characteristics curves•Heater, General Lighting product, Electronic Circuit, etc.•Motor, etc.
The Characteristic Curve of the Inverse Curve DPR is classified into the Cold Curve and Hot Curve.
•Cold Curve : The curve applied when a motor initially starts. The curve is 6 to 8 times of normal operating current (For motors, the starting current is 600 to 800% of normal current).
•Hot Curve : The curve applied during a motor operates. It is similar to the heat characteristic curve of a common motor,so it is more efficient in protecting a motor by choosing the close point to the motor’s critical temperature as a protection point.
•For DPR, the characteristic curve shows the Cold Curve when the motor is initially starting and Hot Curve after the setting time.Ex) When starting, if the operating time is set at 10 sec, it shows Cold Curve. After the setting time, it shows Hot Curve.During the operation, it trips though 600% of rated current flows for only 1.3 sec. according to the Hot Curve characteristic.
Inverse Curve DPR may trip in case motor is restarted several times in serial, so please restart it with minimum 3 sec. interval.The motor with frequent direct-reverse operation should be used extending the setting time a little. However, please consult withus for the application of crane and hoist.

Note1. Standard 3 phase-4 pole squirrel induction motor is based.2. TH setting ranges are based on the motor full load current3. When wiring on the part of the dotted line in the picture,
the ratings of TH are applied by multiplying “1/ 3 ” of the setting ranges above.
4.Sectional area of wire is the thickness which can be connected to MCM. MCCB ratings are for the “line protection”.
5. Breaking Capacity was not considered.6. Separate mounting unit for TH is recommended for Y-△ start.
(Type combined with MC can be used when wiring on the part of the dotted line in the picture.)
