回路遮断器。[Scope of Claim for Utility Model Registration] (1) A contact arm that is operated by an opening/closing mechanism, consisting of a quick-closing pole that enters quickly at the time of input, and another pole that enters following this quick-closing pole, and a contact arm that is provided on this contact arm. A multi-pole circuit comprising a movable contact fixed to the movable contact, a movable contact fixed to the movable contact, and a fixed contact facing the movable contact at each pole, and the contact arms of each pole are connected by a crossbar. In the circuit breaker, the contact arm of the early-closing pole has the same rotation center as the contact arm A connected to the other pole by the crossbar, and has a long hole in the contact arm A. a contact arm B to which the movement of the contact arm A is transmitted by a movably engaged pin;
A multi-pole circuit breaker characterized in that the contact arm B is divided into two parts, and the contact arm B is provided with the movable contact. (2) A spring A is interposed between the movable contact and the contact arm B, and a spring B is interposed between the contact arms A and B so that the contact arm B opens relative to the contact arm A. A multi-pole circuit breaker according to claim 1 of the utility model registration claim.
