Claims

[Claims for Utility Model Registration] (1) A mechanism 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. A multipole circuit breaker comprising a latch engaged with the cradle of the opening/closing mechanism and actuated by an automatic tripping device, a support shaft rotatably supporting the latch, and a support shaft fixed to the support shaft. a lever that engages with the cradle and is always biased in the tripping direction of the cradle; and an actuator that is fixed to the support shaft and engages with the internal accessory device, wherein the support shaft is made of metal. an insulating cap is inserted and fixed at the end of the support shaft, the part of the insulating cap penetrates the interphase wall, and the actuator is inserted and fixed into the insulating cap,
The multi-pole circuit breaker is further characterized in that the insulating cap is provided with a retaining collar, and the collar is brought into contact with a side surface of the interphase wall on the side of the mechanism pole. (2) Utility model registration claim 1, which is characterized in that it has an interphase barrier that is fitted and attached to the interphase wall by a protrusion and a groove, and an insulating cap is rotatably inserted into the hole of the interphase barrier. Multi-pole circuit breakers as described in section.
