INSTRUCTION MANUAL

2

Failure to follow these in-

structions may result in dan-

gerous conditions, which in

turn could lead to severe

personal injury or even

death.

Failure to follow these instruc-

tions may result in dangerous

conditions, which could result

in moderate to slight personal

injury or damage to equip-

ments and facilities.

Safety precautions

Warning for possible electrification under

certain conditions.

¡Do not use this device on the conditions over ratings. Otherwise, ground-fault or short circuit fault could occur due to

dielectric breakdown. Or explosion could occur due to a short circuit protection failure.

¡Do not touch the terminals. There is a risk of electrical shock.

DANGER

CAUTION

¡Before using this device, make sure to read this Instruction manual thoroughly. The cautionary items noted herein are of

the utmost importance for the safe use of this device, and should always be strictly followed.

¡Please make sure that the final user receives this Instruction manual.

¡This Instruction manual is prepared for an electrical expert.

The following symbols have been used:

This means prohibition. Never ignore this

instruction.

Warning for possible outbreak of a fire

under certain conditions.

Be sure to follow these instructions with-

out fail.

DANGER

CAUTION

¡A qualified electrician should install this equipment.

¡Inspection and maintenance should be performed by a qualified electrician and only after shutting off the electric power

and verifying that there is no voltage present. Failure to do so could result in an electrical shock.

¡Make sure to tighten the terminal screws to the torque specified in the instruction manual. Failure to do so could result

in fire.

¡Do not install in areas subject to high temperatures, high humidity, dust, corrosive gas, vibrations, or shocks, etc. To do

so could result in malfunction or fire.

¡Install so that trash, concrete dust, iron filings or rainwater cannot get into the circuit breaker unit interior. Failure to do

so could result in malfunction or fire.

¡When the circuit breaker trips automatically, always clear the source of the malfunction before closing the circuit

breaker. Failure to do so could result in fire.

¡Terminal screws should be tightened periodically. Failure to do so could result in fire.

¡Use the breaker in 50/60 Hz. Failure to do so could result in malfunction or fire.

¡Dispose of this product as industrial waste.

On AE4000-SWA,AE4000-SW ~

AE6300-SW, the center of gravity of the

cradle is located at the terminal posi-

tion. When the main body is removed

from the cradle, the cradle may turn over

backward. Take measures against

overturning.

When the main body is drawn out,

the center of gravity shifts to the

front. If the cradle is not secured,

take measures against overturning

and dropping.

CAUTION

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.

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.

Insert the breaker until the lock plate protrudes. If it does

not protruding, the breaker may not be connected com-

6 After releasing the lock plate, turn the drawout handle

clockwise.

(Note:)

(a) Do not try to pull the unit out while inserting it as

doing so may not accurately display the posi-

tion. If the unit is pulled out in the middle of the

inserting process, pull it out to the circuit dis-

connecting position and then insert it again.

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.

(Note:)

(a) After insertion is completed, do not turn the

drawout handle further.

(b) The drawout position indicator shows the position

(CONNECT or TEST) of the breaker at the time

when the lock plate protrudes. When the lock

plate is in the released state, the indicator shows

¡Manual charging operation is also possible using the charg-

ing handle.

¡Although the charging motor has a short time rating it can

be continuously operated for up to ten times.

¡Since the charging complete switch is separate from the

motor charging circuit, the sequence can be arranged as

required.

Note 1: Contents in parentheses show the case of AE4000-SWA 4-pole,

AE4000-SW, AE5000-SW and AE6300-SW.

24 V DC and 48 V DC products of AE4000-SWA 4-pole, AE4000-SW,

AE5000-SW and AE6300-SW cannot be manufactured.

Note 2: Operating power supply capacity of the motor charging should be

prepared not to be lower than an applicable voltage range during

charging.

< 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 N·m or less.

Charge operation: 7 to 8 times

8 To drawout the breaker, pull each side equally.

Otherwise (in the case of drawing slantwise) the breaker

can not move smoothly.

When ACB is installed at a high position, please do the

Drawout / Insert operation by two people.

(Note:)

Since the center of gravity is by the terminal, the

Cradle support is required to prevent from falling.

Opening/Closing operation

< Conditions of ON operation >

ON operation will be possible, when all the following condi-

tions have fulfilled.

Manual operation

< Closing >

Push the ON button, the breaker will close. The ON/OFF

indicator will show “ON”, and the charging indicator will show

“DISCHARGED”. Operating force is less than 50N.

(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.

< Opening >

Push the OFF button, the breaker will be opened and the

ON/OFF indicator will show “OFF”. Operating force is less

than 50N.

Electrical operation

< 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.)

< Opening >

The use of a shunt trip device (SHT) or an under-voltage trip

device (UVT) enables to electrically trip the breaker.

When an SHT is used, apply the rated voltage to C1 and C2 on

the control circuit terminal block.

When a UVT is used, open the trip terminals DT1 and DT2 on

the control circuit terminal block. (A short-circuiting bar has been

fitted before shipment. Remove the bar before using the termi-

nals.)

Or turn off an applied voltage to D1 and D2 .

< Procedures for releasing door interlock >

1 Even when the breaker is on, the interlock can be manually released.

For this purpose, make a hole 7 or more in diameter in the panel door. (See the following figure.)
