Electric open/close operation
< Closing >
Opening operation can be performed electrically by using a closing coil (CC). By applying the rated voltage to A1 and
A2 on the control circuit terminal block, the breaker can be closed.
The pumping preventing relay that performs only one operation with one input command is built in.
To close again, turn OFF the closing coil control supply
(between A1 and A2 ) once, and apply the rated voltage again. For a closing command to CC, wait at least a 0.5 sec. interval after completing charging and turning OFF the breaker.
(Caution)
For a closing command to CC after completing charging, wait at least a 0.5 sec. interval. If a closing command is given within 0.5 sec. after charging completion, the design life of the opening/closing operation may be shortened.
In some cases, the breaker does not close by a closing command given within 0.5 sec. after a manual OFF operation or an OFF operation by SHT.
When an undervoltage trip device (UVT) is equipped, the breaker does not close unless the power supply is applied.
(After applying the control supply to UVT, wait 1.5 sec. for the closing operation to become available.)
If undervoltage tripping device ( UVT ) is UVT with a-contact, wait for 1.8 sec. Instead of 1.5 sec.
< Opening >
Opening operation can be performed electrically by using a shunt trip device (SHT) or undervoltage trip device (UVT).
For SHT, apply a rated voltage to C1 and C2 of the control circuit terminal block.
For UVT, open between the trip terminals DT1 and DT2 of the control circuit terminal block. (A short-circuit bar is equipped when shipped from the factory. Remove this before using.)
Alternatively, turn OFF the voltage applied to D1 and D2 .

Functions of electronic trip relay (ETR) parts
< Function description of each part >
① ERR. LED, contact output
When any abnormality or setting failure is found in the
ETR, this provides a notification of the abnormal status.
When the power supply type is P3 ~ P5, contact output is given between 513 and 574 on the control circuit terminal block.
• Functional abnormality in ETR (microprocessor, H/W)
• Incorrect setting (mis-setting of Int/MCR)
• Abnormality in in-breaker wiring related to ETR
② RUN LED (ETR)
ETR indicates the operable state. If the control power supply is applied, or when approx. 10% of the rated current flows to the main circuit, the internal circuit is activated, turning on this LED.
③ RUN LED (option setting module) Option
This indicates that the option setting module is in an operable state.
If the control power supply is applied, or when approx.
10% of the rated current flows to the main circuit, the internal circuit is activated, turning on this LED.
④ Trip cause indicator (LED, contact output) Option
The cause of a trip is indicated by LED. When the power supply type is P3 ~ P5, a contact output is given between 513 (common) and 524 , 534 , 544 , or 554 on the control circuit terminal block.
PAL LED will blink when the current exceeds the prealarm current setting (Ip), and will be lit after 1/2 of the
LTD time is passed. At this time, the contact output will also be made.
⑤ TAL LED, contact output Option
The ETR temperature detector becomes operable when a TAL sensor is installed. When the power supply type is P3 ~ P5, a contact output is given between 513 and
564 on the control circuit terminal block. When the temperature drops, the output will be reset. To retain the output, use an external sequence.
⑥ MCR (Making-current release) Option
The setting can be switched between the instantaneous current (INST) and MCR functional current (MCR). In the
MCR setting, INST characteristic is enabled from the time of breaker closing (OFF to ON), and after closing, the INST characteristic becomes disabled.
If specified at the time of ordering, an MCR switch is built in to the breaker. When shipped from the factory, this is set to the INST side.(Fig. 21-2)
⑦ RESET button
To reset the trip cause indicator (LED, contact output), use the “RESET” button in front of ETR, or short-circuit
RS1 and RS2 on the control circuit terminal block for 0.5 seconds or longer.
(The power supply type P1 and P2 are not provided with the function to reset from the control circuit terminal block.)
There is also a function to temporarily lock LTD and STD to test the INST characteristic by using a dedicated field testing device. (For operating instructions, refer to the instruction manual of the tester.)

To provide ground fault protection for a 3-pole breaker used in the 3-phase 4-wire system, a neutral pole CT (NCT) is required. For the specification, refer to the catalog.
For the installation of the NCT, refer to the instruction manual provided with the NCT.
The G1 module cannot be attached to the AE630-SW low rating models (CT rating:
500 A, 315 A, 250 A).
To set the ground fault pick-up current Ig to 0.1, the control power supply must be applied. (If the control power supply is not applied, ground fault protection cannot be provided correctly.)

For the drawout type, the cables should have the length which allow the control circuit terminal block to be moved to the left or right by 5mm.
When a coil load is connected in the same control circuit as the ETR, surge absorbers are required to absorb the surge voltage.
OCR alarm (AL)
The contact output of the OCR alarm (Standard type AL) is the one-pulse output and the output time is 30~50ms.
For this reason, this output needs self-holding circuit.
For Power supply type P3 and P4, the high sensitive relay used in contact output may cause the chattering noise (wrong output of 1ms level) during ON and OFF operation, depending on the
Panel placing condition. When it is used in the quick responsive sequence, the filter circuit of a few milli-second (ms) should be provided or the double reading sampling should be implemented.
Closing coil (CC)
As CC is one-pulse driven, it is not necessary to insert AXb for burning prevention purposes.
Inserting AXb will cause anti-pumping function to be ineffective.
Under voltage trip device (UVT)
Use the switch that can open and close 150V DC, 0.5A for remote trip.
Remote trip terminal has short bar at shipment, so remove it before using this function.
Disconnect the voltage input wires during dielectric testing of main circuit.
Since some terminals are polarized, the wiring should be done correctly as the polarity shown in the wiring diagram when the control voltage is DC. Auxiliary switch (AX) Standard type has no polarity.
Alarm reset (Terminal: RS1 and RS2 ) is available only for Power supply type P3, P4 and P5.
For Power supply type P1 and P2, it can not be reset from the Control circuit terminal block ( RS1 and RS2 ).

FG (Terminal: P4 ) is the protective earth for power supply (Terminal: P1 , P2 ).
It is recommended to use this terminal to reduce surge (M8 screw required).
