Spring-Charging Motor (MCH)

The spring-charging motor automatically

charges the spring mechanism for closing

the circuit breaker and also recharges the

spring mechanism when the circuit

breaker is in the ON position.

Instantaneous reclosing of the circuit

breaker is thus possible following circuit

breaker opening. The spring-mechanism

charging handle is used only as a backup

if auxiliary power is absent.

The spring-charging motor is equipped as

standard with a limit switch contact (CH)

that signals the charged position of the

mechanism (springs charged).
