Abstract

An actuating unit or actuating mechanism and release for a circuit breaker. The magnetic mechanism of the release includes a magnet armature, which can move linearly in a magnet coil, is in the form of a tripping plunger and can be moved towards a permanent magnet counter to the force of a storage compression spring and is held fixedly by said permanent magnet in the case of a magnet coil through which no current is flowing. The tripping unit is in the form of a mechanical force store. After a tripping action, the mechanical force store needs to be reset manually again. For this purpose, a rotary movement of the drive shaft with an angular displacement of from 20 to 30 degrees takes place in the opposite direction to the ON switching rotary movement.
