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.

If an MO charging motor is installed and powered, the closing spring charges automatically

each time the circuit breaker closes.
