The side sectional view showing the state at the moment of tripping, and FIGS. 4 to 6, all show an embodiment of this invention. FIG. 4 is the side sectional view showing the OFF state, and FIG. 6 is a side sectional view showing the ON state, and FIG. 6 is a side sectional view showing the tripped state. In the figure, 1 is a housing, 2 is an operating handle, 4 is a link, 5 is a movable element, 7 is a locking lever, 12 is a movable contact, 16 is a fixed contact, 17 is a coil, 23 is a plunger, 26 is a rod, 30 is a bimetal, and 45 is a stopper. In addition, in the figures, the same reference numerals indicate the same or corresponding parts.

Claims

[Scope of utility model registration request]

(1) A housing that has an opening and houses an internal mechanism; an operating handle that protrudes from the opening of the housing and can be turned on and off from outside the housing; one end is rotatably connected to the operating handle; a link forming a toggle link mechanism together with the operating handle, and a movable contact rotatably supported and disposed at one rotating end opposite the fixed contact;
The other rotating end of the movable element is normally connected to the link, and the movable element is interlocked with the link so that the movable contact moves into and out of contact with the fixed contact, and when an overcurrent of more than a predetermined value flows, the link and the an overcurrent tripping device that disconnects the movable element and separates the movable contact from the fixed contact; and an overcurrent tripping device provided in the casing, when the overcurrent tripping is performed by the overcurrent tripping device. A circuit breaker comprising a stopper that prevents movement of the link so that the operating handle is in an intermediate position between the ON and OFF states.

(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, wherein 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, wherein the stopper is formed integrally with the casing.

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