操作機構。 It has a tripping latch that is linked to the tripping operation by the armature of the tripping electromagnet, and an engagement latch that keeps the tripping latch in the closed state, and the engagement latch and the tripping latch are connected by the closing operation. In the closing operation mechanism for a circuit breaker, which is rotated to a closed state position and held in the closed state by engaging both latches, a weight is provided on the armature of the tripping electromagnet, and a weight is provided on the armature of the tripping electromagnet. A spring is provided that biases the external latch in the direction of contact, and during the closing operation, the spring hits the armature just before the tripping latch engages with the engagement latch, and absorbs the biasing force of the rotational movement of the tripping latch. A closing operation mechanism for a circuit breaker, characterized in that:
