Electric open/close operation
< Closing >
Opening operation can be performed electrically by using a
closing coil (CC). By applying the rated voltage to A1 and
A2 on the control circuit terminal block, the breaker can be
closed.
The pumping preventing relay that performs only one oper-
ation with one input command is built in.
To close again, turn OFF the closing coil control supply
(between A1 and A2 ) once, and apply the rated voltage
again. For a closing command to CC, wait at least a 0.5
sec. interval after completing charging and turning OFF the
breaker.
(Caution)
For a closing command to CC after completing
charging, wait at least a 0.5 sec. interval. If a clos-
ing command is given within 0.5 sec. after charging
completion, the design life of the opening/closing
operation may be shortened.
In some cases, the breaker does not close by a
closing command given within 0.5 sec. after a
manual OFF operation or an OFF operation by SHT.
When an undervoltage trip device (UVT) is equipped, the
breaker does not close unless the power supply is applied.
(After applying the control supply to UVT, wait 1.5 sec. for
the closing operation to become available.)
If undervoltage tripping device （ UVT ） is UVT with
a-contact, wait for 1.8 sec. Instead of 1.5 sec.
< Opening >
Opening operation can be performed electrically by using a
shunt trip device (SHT) or undervoltage trip device (UVT).
For SHT, apply a rated voltage to C1 and C2 of the control
circuit terminal block.
For UVT, open between the trip terminals DT1 and DT2
of the control circuit terminal block. (A short-circuit bar is
equipped when shipped from the factory. Remove this be-
fore using.)
Alternatively, turn OFF the voltage applied to D1 and D2 .
