Circuit breaker operation
2.1 Description
RESET re-arm button
The RESET re-arm button is used to reset the circuit breaker after tripping
(see Chapter 07 Circuit breaker closure after a trip operation).
The operation of the RESET re-arm button depends on the Auto or Manual mode set using the
adjustment dial on the right.
- Auto mode, in which it is not necessary to press the RESET re-arm button before closing the
circuit breaker again after tripping.
This mode is usually used if the circuit breaker is remotely monitored, as it can be closed
without requiring a person to perform the action on-site.
- Manual mode, in which the RESET re-arm button must be pressed in before closing the
circuit breaker again after tripping.

Closing spring
The closing spring is used to mechanically close the circuit breaker. It must be charged first,
and there are two procedures for this:
- Manual charging
Charge the spring using the charging handle until the status of the indicator changes.
- Automatic charging
If an MO charging motor is installed and powered, the closing spring charges automatically
each time the circuit breaker closes.
