Claims

[Claims for Utility Model Registration] (1) A breaker case having multiple poles, a mechanism frame installed on a mechanism pole with an opening/closing operation mechanism of the breaker case, and a mechanism frame supported by this mechanism frame. and a trip bar whose end extends to an adjacent pole without an opening/closing mechanism of the shunt breaker case, an automatic tripping device for tripping the trip bar, and a trip bar provided on the adjacent pole side of the shunt breaker case. A multi-pole circuit breaker having a trip button for tripping a trip button from outside the case, characterized in that an end of the trip bar on the side that comes into contact with the trip button is supported on the breaker case by a support member. Pole circuit break. (2) A utility model characterized in that the support member is provided with a hole for inserting and supporting the end of the trip bar, and the cutter case is provided with a recess for fitting and fixing the support member. A multi-pole circuit breaker according to claim 1. (3) Claim 2 of the utility model registration claim characterized in that the hole in the support member is made slightly larger than the outer diameter of the end of the trip bar so that a gap is formed on the non-supported side of the end. Multi-pole circuit breakers.
