Claims

[Scope of utility model registration request]

(1) A casing having an opening and housing an internal mechanism, which protrudes from the opening of the casing and is turned on and off from the outside of the casing.
an operating handle which is operable and is always oriented and biased toward the OFF position; a link whose one end is rotatably connected to the operating handle and forms a toggle link mechanism together with the operating knob; and a rotatably pivoted link; and has a movable contact arranged opposite to the fixed contact at one rotating end, and the other rotating end is always connected to the link so that the movable contact moves into and out of contact with the fixed contact. a movable element interlocked with the link; an overcurrent tripping device that disconnects the link and the movable element to separate the movable contact from the fixed contact when an overcurrent exceeding a predetermined value flows; and a stopper provided on the movable element to prevent movement of the link so that the operating handle is at an intermediate position between the ON and OFF states when the overcurrent trip is performed by the overcurrent trip device. circuit breaker with.

(2) The other end of the link is normally held between the locking lever rotatably supported by the mover and the mover, so that
The circuit breaker according to Claim 1, characterized in that the mover is always connected to the link.

(3) The circuit breaker according to claim 2, wherein the link is comprised of a U-shaped pin.

(4) The circuit breaker according to any one of claims 1 to 3, characterized in that the stopper is formed integrally with the mover.

(5) The circuit breaker according to any one of claims 1 to 3, wherein the stopper is made of an elastic body.
