項記載の回路しや断器。[Claims for Utility Model Registration] (1) A trip bar rotated by a tripping mechanism, a latch actuated by the trip bar and biased toward the reset position, and a latch removably engaged with the latch. a latch, a combined spring biasing the latch into engagement with the latch and biasing the trip bar toward the reset position; In a circuit switch or disconnector having a lever that operates to open, the position where the combined spring contacts the trip bar is closer to the rotational fulcrum of the trip bar at the start of tripping, and is lower than the contact position at the start of tripping at the start of reset. A circuit breaker characterized by being located away from a rotational fulcrum. (2) The trip bar is provided with an engaging protrusion that engages with the combined spring, and a protrusion for abutting at the start of a trip is formed near the rotational fulcrum of the engaging protrusion. Claim No. 1 for Utility Model Registration in which a protrusion for contact at the start of reset is formed on the side
