Charging Operation - Mitsubishi Electric AE-SW Series Instruction Manual

⑧ When pulling out the breaker, be sure to do so evenly
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.
For a breaker installed in an elevated location, perform
this operation with two people.
(Caution)
AE4000-SWA and AE4000-SW ~ AE6300-SW have
their cradle center of gravity on their terminal areas.
Be sure to take preventative measures against a fall or
drop by installing a support for the cradle (Fig. 16-1).

Charging operation

< Manual charging >
Press the charging handle down at full stroke 7 or 8 times
until a click sounds. (It is completion when a charging han-
dle becomes light.) Then, the closing spring will be fully
charged. The charging indicator will show CHARGED.
(Caution)
Do not forcefully press down the charging handle.
Doing so could result in breakage.

< Motor charging (MD) >
The closing spring is charged by an electric motor. When
the breaker is closed, the spring is charged automatically
(ON-charge method).
 Manual charging operation is also possible using the
charging 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.

OFF charging method is also available.
The closing spring is charged
automatically when the breaker is
opened. This is available only by
externally connecting b contact (AXb) of
the auxiliary switch to the motor
charging circuit in series.
In case of DC power supply, please use
high capacity auxiliary switch (HAX).

Note1 ) Values in parentheses show values for AE4000-SWA 4 pole and AE4000-SW ~ AE6300-SW.
Note2 ) We cannot manufacture AE4000-SWA 4 pole and AE4000-SW ~ AE6300-SW in 24V DC and
48V DC rating.
Note3 ) When choosing from the power supply capacity required to perform motor charging, make sure
that its voltage after a voltage drop at power input is still within the applicable voltage range.
Note4 ) These values are for reference, not guaranteed values.
Note5 ) Common use for 50 and 60Hz in AC.
