Instructions for VD4 CB operations
The geared motor automatically recharges the
spring after each closing operation until the
yellow indicator (5) appears. If the power is
cut off during charging, the geared motor
stops and automatically starts recharging the
springs again when the power returns.
In any case, it is always possible to complete
the charging operation manually.
c) Circuit-breaker closing
The operation can only be carried out
with the closing spring completely charged.
For manual closing, press the push button
(3 - figure 11.1)
When there is a shunt closing release, the
operation can also be carried out remotely by
means of a special control circuit.
Closing having taken place is indicated by the
signaling device (4 - figure 11.1)
d) Circuit-breaker opening
For manual opening, press the push button
(2 - figure 11.1). When there is a shunt opening
release, the operation can also be carried out
remotely by means of a special control circuit.
Opening having taken place is indicated by the
signaling device (4 - figure 11.1)
