極回路遮断器。[Claims for Utility Model Registration] A multi-pole circuit breaker comprising a mechanism pole with an opening/closing link mechanism and a pole without an opening/closing link mechanism adjacent to this mechanism pole and having an alarm switch, the mechanism pole a support shaft rotatably supporting the latch, a support shaft fixed to the support shaft and engaged with the cradle and permanently attached in the tripping direction of the cradle; an actuator fixed to the support shaft and engaged with the alarm switch, the arm detaches from the cradle and rotates when the cradle is activated, and the rotation of the arm causes the support shaft to rotate. A multi-pole circuit breaker in which the alarm switch is switched by rotating the actuator through the switch, wherein the link of the opening/closing link mechanism is shaped so that it does not hit the arm when it is turned off.
