する回路しや断器。 A toggle link mechanism is operated by operating a handle rotatably provided on the case to move the movable contact toward and away from the fixed contact, and when an overcurrent is detected, the tripping device operates to close the link of the toggle link mechanism. The rotatably connected catch is unlocked, and as the catch rotates, the movable contact is separated from the fixed contact via the toggle link mechanism, and the handle is positioned at the trip position. In the toggle link mechanism, the catch is provided with a stopper in the vicinity of the toggle link mechanism that stops against a stopper provided on the case to restrict the rotational position of the catch when the tripping device is operated. 1. A circuit and disconnector characterized in that a toggle spring made of a tension coil spring of a link mechanism has a smaller winding diameter at a portion corresponding to the blocking piece.
