摘要： A circuit breaker has at least two handle lock screw engagement portions to which a handle lock device is attached formed on a case at positions different from a position of an attachment screw for integrating a case including a plurality of divided bodies. The handle lock device has at least two attaching screws disposed, the attaching screws engaging with the handle lock screw engagement portions of the circuit breaker and attaching the handle lock device at a regular position on the circuit breaker. The handle lock device has a handle locking portion disposed, the handle locking portion restricting the knob portion from moving to an ON position even when the attaching screws are incorrectly attached to the handle lock screw engagement portions.

摘要： The main body frame includes a first frame including a flexible protruding plate portion, a second frame facing the first frame in a first direction to form the housing section, and a snap-fit mechanism connecting the first frame to the second frame. The snap-fit mechanism includes a fitted portion provided on the flexible protruding plate portion and a fitting projection portion provided on a side wall of the second frame and fitting with the fitted portion. The fitting projection portion and the fitted portion are fitted by bringing the first and second frames into relative proximity in the first direction, and the fitting is released by relatively displacing the first and second frames in a second direction orthogonal to the first direction.

摘要： A case has an engagement hole formed in a side surface thereof in the width direction, a cover has a projecting piece formed thereon, the projecting piece projecting toward the case side, and a tip portion of the projecting piece is fitted into the engagement hole from the inside. A reset bar has a recessed portion formed in a preset range extending in the depth direction and the circumferential direction within the outer peripheral surface of the reset bar and, when positioned at either an initial position or an automatic reset position, prevents the tip portion from being pushed inside by having the outer peripheral surface opposed to the back side of the projecting piece. In addition, when positioned at a manual reset position, the reset bar allows the tip portion to be pushed inside by having the recessed portion opposed to the back side of the projecting piece.
