Claims

[Scope of claim for utility model registration] It is provided so that it can be moved into and out of contact with a fixed contact. A movable contact device, a lower link connected at one end to the movable contact device, an upper link connected to the lower link and forming a toggle link mechanism together with the lower link, and usually locked to a tripping mechanism. In the circuit breaker, the movable contactor comprises a fredle connected to the upper link, a tiltable operating handle connected to the toggle link mechanism by an actuating spring, and a frame holding these mechanisms. A circuit breaker, characterized in that the frame is provided with a portion of a stopper that stops movement of the connecting portion between the upper link and the lower link when the device is closed and opened.
