Unpacking ① Make sure that the packing case is free from any abnormality such as being broken and/or wet. ② Check the indication on the package and the rated nameplate of the breaker, and confirm that it matches your order. Serial number is indicated on the rated nameplate and on the cradle nameplate (Fig.

Installation < Drawout type > AE630-SW ~ AE3200-SW, AE2000-SWA, AE4000-SWA Installation surface flatness 1 mm or less Insert M12 bolts from above, and attach the cradle. Max. Bolt 14 mm lAppropriate tightening torque Bolt size Tightening torque (N m) 45±5 Earth terminal Fig.
Installation of the drawout handle The drawout handle can be installed either onto the right or left of the cradle as required. A drawout handle, installation bracket, installation screws, and hexagon nuts are provided with the breaker. Installation onto the left side Installation onto the right side Drawout handle Installation bracket...
Connection Use M12 screws (made of copper), spring washers, and small washers to connect to the conductors. Clean the contact surface and securely tighten the screws with a appropriate torque. The connecting area on main circuit terminal of the breaker is different depending on the shape of the breaker’s terminal. Refer to the outline dimensions in the catalog.
Since fault current owing through the conductors causes large electromagnetic forces, the conductors should be secured rmly, using the values in the below table as a reference. Max. distance between xing support and breaker bus bar should be less than 200mm. Table 11-1 Electromagnetic force per 1 m of conductor (in the case of three phase short circuit) (N/m)
Insert operation DRAWOUT positionCONNECT position ① Pull the lock lever toward you (step 1), unhook the lock lever ② With the extension rail pulled out to the furthest position, lift the from the cradle, and then pull out the extension rail (step 2). breaker once by using a lifter or dedicated lifting hook (HP), and then lower the breaker down onto the drawout rail.
⑤ Press in the lock plate until it clicks onto the latch, and ⑥ Unlock, release your hands from the lock plate, and unlock. rotate the drawout handle clockwise. (Caution) (Caution) (a) If unlocking the lock plate feels difficult, slightly rotate Do not draw out during the insert operation.
Drawout operation CONNECT position DRAWOUT position ① ① For AE4000-SW ~ AE6300-SW, unfasten the two fixing bolts on both sides of the cradle, and unlock. If dra- wout is performed without unlocking, the cradle and the drawout mechanism may be damaged. (Fig.
⑤ When the breaker is drawn out to the TEST position, ⑤ the drawout position indicator shows TEST position, and the lock plate is protruded automatically, locking the drawout handle rotation. (Caution) Do not rotate the drawout handle while the lock plate is protruded.
⑧ When pulling out the breaker, be sure to do so evenly ⑧ on the right and left sides. (Do not forcefully pull the right or left area only.) If it is uneven (if the breaker is coming out diagonally), it does not come out smoothly.

Electric open/close operation CC circuit diagram < Closing > Opening operation can be performed electrically by using a Breaker CC unit closing coil (CC). By applying the rated voltage to A1 and A2 on the control circuit terminal block, the breaker can be closed.
Door interlock (DI) < Procedures for releasing the door interlock > Interlocks can be manually released even if the breaker is in the ON state. For this, make a hole of ø7 or larger in the panel door. (Refer to Fig. 19-1) For the details such as installation and adjustment methods, check the instruction manual provided with the door interlock.
Shutter lock (SST-LOCK) When pulling out a breaker equipped with a safety shutter (SST) from the cradle, its safety shutter can be locked in the closing position so that the live parts cannot be touched. Padlock (shackle diameter ø5 or less) A padlock (shackle diameter ø5 or less) is provided by the customer.
