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.

and there are two procedures for this:
- Manual charging
Charge the spring using the charging handle until the status of the indicator changes.
