The movable contact has a tripping mechanism including a movable link, and a trip lever that is interposed between the movable contact plate and the movable contact plate and unlocks the pressing force of the movable contact plate by the operation of the overcurrent detection device. In a circuit breaker in which the plate is turned on and off by the operation knob and the movable contact plate is cut off when an overcurrent is detected, the tripping mechanism is moved by the overcurrent detection device on the curved surface of the swing link facing the trip rod. A contact is provided where the sliding friction between the contact plate and the trip rod increases significantly during the trip operation that unlocks the pressing force of the contact plate, and a mark is provided on the operating knob to indicate the ON and OFF positions of the operating knob. The case is provided with a display section in which the mark can be seen in the middle, and the operating knob is locked at the hit position during the tripping operation, and the mark is made visible from the display section at that position.
