ABSTRACT:
An energy accumulator for a circuit breaker comprises a cross piece which can be inserted between side walls of the support mechanism of the circuit breaker, which has a substantially U-shaped cross section and against the center part of which coil compression springs are braced. With their opposite ends, the springs rest against a movable abutment which likewise has a U-shaped cross section. A push rod which goes through one of the springs in its longitudinal direction is guided in the cross piece and has a transverse hole for inserting a securing pin in the partially cocked state of the springs. Between the legs of the cross piece there are inserts which have an extension pointing in the direction of the movable abutment. Thereby, a space for the engagement of a leg of the movable abutment is formed if the springs are tensioned more heavily.
