Claims

[Claims for Utility Model Registration] (1) A movable contact having a movable contact that is brought into contact with and separated from a fixed contact, an opening/closing operation mechanism that opens and closes the movable contact, and a cradle of the opening/closing mechanism that connects the movable contact to the movable contact. a circuit breaker having an automatic tripping device for tripping a child, a locking mechanism that engages with the cradle to position the cradle; and a locking mechanism that engages with the cradle to prevent the locking mechanism from being rotated by the cradle; and a trip bar that engages with the latch lever to prevent the latch lever from being rotated by the locking mechanism, and when the trip bar is rotated by the trip member of the automatic tripping device at the time of tripping, the latch lever is When the cradle comes off the trip bar and is released together with the locking mechanism, the cradle rotates the released locking mechanism and the latch lever, causing the movable contact to trip. 1. A circuit and disconnector characterized in that a spring spring biases the locking clamp in a direction to engage the locking clamp, the latch lever to engage the locking clamp, and the trip bar to engage the latch lever. (2) Insert the ring portion of the double torsion spring into the rotation center shaft of the locking mechanism, and engage the folded portion of the spring with the locking mechanism, one end of the spring with the latch lever, and the other end of the spring with the trip bar. A circuit breaker or circuit breaker according to claim 1 of the utility model registration claim, characterized in that:
