Claims

[Claims for Utility Model Registration] A multi-pole circuit comprising a mechanical pole with an opening/closing mechanism and an adjacent pole without an opening/closing mechanism located across the interphase wall from this mechanism pole and having an internal accessory device such as an alarm switch. In the circuit breaker, the casing of each pole is composed of a base and a cover, and a push rod and a trip bar for operating an alarm switch, which are incorporated in the opening/closing mechanism, face the adjacent pole side from an opening in the interphase wall. Further, in the case where the opening is formed by cutting into the cover or base from the mating part, the pressing rod is arranged near the mating part to make the opening as small as possible, and the trip bar is made wide. A multi-pole circuit breaker, characterized in that it is formed to serve as an insulating wall between the push rod and the automatic tripping device of the adjacent pole.
