Charging operation
Fig. 15-3
¡
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.

The closing spring is electrically charged.
This is an “ON charge method”, in which the spring is auto-
matically charged when the breaker is closed.

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

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.
