Claims

[Claims for Utility Model Registration] (1) A response device that operates when an overcurrent exceeding a predetermined value is detected, a trip mechanism that operates due to the operation of the response device, and a trip mechanism that is unlatched by the operation of the trip mechanism. In a circuit or disconnector comprising a lever that rotates, a movable contact that opens and opens via a link mechanism by the rotation of the lever or operation of a handle, and a frame that supports the lever etc. , a lever stopper is provided at an intermediate position of the frame that is located inwardly from the end of the frame away from the movable contact of the movable contact, and the lever is located inwardly from the end of the lever on the movable contact side. A circuit breaker characterized in that an engaging part is provided at an intermediate position, and the engaging part is engaged with the lever stopper to determine the position when the lever is tripped. (2) Utility model registration claim 1 in which the engaging part is a protrusion formed by stamping on the side of the lever
Circuit breakers and breakers as described in section.
