Fig... 6-6 To lift the breaker types AE4000-SW, AE5000-SW and AE6300-SW, be sure to use four ropes with a length of 1 m or more, or use the lifting truck, apply for further detail...

Page 7

In the case of AE4000 ~ 6300-SW, insert four M12 bolts from the bottom and two M12 bolts from the back to mount the cradle as shown in Fig... 7-3... In the case of 4P FN type, insert six M12 bolts from the bottom and two M12 bolts from the back to mount the cradle as shown in Fig... 7-4...

Page 8

Note: The drawout handle cannot be mounted on the left side of the cradle when the cradle is provided with a mechanical inter lock (MI) or a door inter lock (DI)... Mount the handle at an appropriate position in the panel...

Page 9

If the screw is tightened with exces- sive torque, the terminal and the screw may be damaged... Tighten the screw to the specified torque...

Page 10

Note: Table 10-2 shows conductor size based on IEC 60947-1 in ambient temperature 40C and open air... And the examination circuit is as Fig... 10-1

Page 11

3 Slowly push the breaker in unit it does not move... To insert the breaker, push each side equally... Otherwise (in the case of inserting slantwise) the breaker can not move smoothly... When ACB is installed at a high position, please do the Drawout / Insert operation by two people...

Page 12

8 Then, push the lock plate to turn the handle clockwise... When the breaker is inserted to the connect position, the lock plate automatically protrudes to indicate that the breaker has been inserted completely... The drawout position indicator shows CONNECT position...

Page 13

the drawout handle insert operation... The drawout position indicator may not function correctly... In this case, pull the unit out to the circuit discon- necting position and insert it to the circuit con- necting position... Then drawout it again...

Page 14

6 Then, push in the lock plate, turn the drawout handle counterclockwise to change the displayed extraction position to the DISCONNECT position until the drawout position indicator shows disconnect position... The handle operation is completed... The breaker can be drawn out by hand...

Page 15

< Manual charging > Press the charging handle down at full stroke 7 or 8 times until a click sounds... (It is completion when a charging handle becomes light... ) Then, the closing spring will be fully charged... The charging indicator will show CHARGED... The operating load is 30 Nm or less...

Page 16

(Note:) When the OFF lock device (Padlock, cylinder lock, castell lock etc... ) is used, the closing operation should be made after the lock is released... Opening and closing of the drawout type breaker must be carried out in either the CONNECT or the TEST position... If an under voltage trip device (UVT) is provided, its rated voltage should be applied before attempting to close and open the breaker...

Page 17

< Closing > Remote closing can be made by emerging the closing coil (CC)... Apply the rated voltage to the control terminals A1 , A2 , and the breaker closes... The unit comprises an unti-pumping circuit which allows only one action without first de-energizing then re-energizing... To re-close the breaker, once turn off power (between A1 and A2 ) to the closing coil, and re-apply the rated voltage to them... When the breaker has an under-voltage trip device (UVT), the breaker cannot be closed if power is not applied... (After power is applied to the UVT, it takes a waiting time of 1... 5 sec until the breaker can be closed... )

Page 18

2 Hold down the OFF button and turn the key to the locking side... Then, the key can be removed, and the breaker will be locked in the off state...

Page 19

The safety shutter can be locked at the closing position so that the live parts are not touched... Prepare a pad lock (5 in diameter) by yourself...

Page 20

7 Reset button The trip indicator (LED and contact alarm output) can be reset by pressing the RESET button on the front panel of ETR or short-circuiting RS1 and RS2 on the control cir- cuit terminal block... (P1 and P2 types are not provided with the function to reset the indication from the control circuit terminal block... ) A function is provided to temporarily lock LTD and STD when the INST function is tested with the field test device... (See the breaker tester instruction manual... )

Page 21

In case of power type P3 or P4, the alarm contact output relay is high sensitive relay... Therefore may occur a chattering noise (approximately 1 ms) by ON/OFF operation of the breaker... Please adopt a time constant filter of several ms, or sampling double reading, or the like...

Page 22

The table shows data obtained on the breakers provided with MCR (optional)... For breakers without MCR, the setting position for MCR is not provided...

Page 23

The table shows data obtained on the breakers provided with MCR (optional)... For breakers without MCR, the setting position for MCR is not provided... When the WM relay is used, the pre-alarm current at the setting, OVER, is the same as that at 1... 0...

The table shows data obtained on the breakers provided with MCR (optional)... For breakers without MCR, the setting position for MCR is not provided...

Page 25

When the 3pole breaker is used on a 3phase-4wires system, the neutral CT (NCT) is required for ground fault protection... As for the NCT installation, refer to instruction manual (included in the product)...

Page 26

< N5 module > The LTD and pre-alarm characteristics of neutral pole be- come 50% of other poles... The STD and INST characteris- tics, however, are same as other poles (100% of other poles)... In case of AE630-SW low rating type, the control supply is necessary for this function...

Page 27

4 When any characteristic setting has been changed, check the tripping characteristics using a field test device... A dedi- cated field test device is available to check the character- istics through the test terminal of ETR... As for the check- ing procedures, see the instruction manual of the field test device...

Page 28

(non-breaking current) = Long time delay pick-up current = Short time delay pick-up current = Short time delay tripping time = Instantaneous pick-up current = Pre-alarm pick-up current = Ground fault pick-up current = Ground fault operating time

Page 30

When the short circuit is interrupted, hot gas blows out discharged from the exhaust port of the arc-extinguishing cham- ber, so provide a clearance as shown in the following table... In case of drawout type, secure appropriate space to prevent the fingers from getting trapped at the time of drawing...

Page 31

3Special altitude If it is used at 2,000 m or higher the heat radiation rate is reduced decreasing the operating voltage rating, continu- ous current capacity and breaking capacity... Moreover the durability of the insulation is also decreased owing to the atmospheric pressure... Apply for further detail...

Page 32

If maintenance and/or inspection should be carried out without cutting of the power supply in an unavoidable cases, wear rubber gloves and insulated boots laying rubber mat on the floor... Use insulated tools and instruments only... An access to the live parts is necessary in this maintenance and inspection work, when workers full attention should be paid to the insulation of human body from the live parts... Any normal opening/closing may be done safely because the live parts are covered with insulated molded case or the like...

Page 33

Withstand Voltage Test AC : Between the live part of the main circuit and the earth : 3500 V AC Between live parts of different poles : 3500 V AC Between main upper terminals and lower terminals : 3500 V AC Between the live part of the main circuit and the control circuit terminal block : 3500 V AC Between the control circuit terminal block and earth : 2000 V AC (The section of dielectric test forbidden shall depend on the instruction on the control circuit terminal label)

Page 34

Please contact our company if any abnormalities on the front cover or the control circuit terminal block... Replace the circuit breaker when the base is found to have trouble... Replace the product if flooding or immersion has occurred... Please contact our company if any abnormalities are found on the rail operation...

Page 35

4... 3 Inspections After a Breaking Operation Inspect the items detailed for periodic inspection (section 4... 2) when the ACB has performed a breaking operation as a result of an overload current or a short-circuit current... Reuse is possible if the relevant criteria are satisfied... A circuit must never be reclosed (locally or remotely) before the cause of the fault has been identified and cleared... However, it is recommended that the ACB be replaced as soon as possible after it has interrupted a large fault current... The ACB should be monitored for unusual temperature rises and other abnormalities until replacement occurs... Refer to the follow- ing chart regarding the level of breaking currents and the treatments to be performed:

Page 36

(Note 1) When you drawout the breaker forcefully, do it after releasing higher breaker... Drawing out the breaker when it is energized may cause serious accident...
