求の範囲第2項に記載の回路しや断器。[Claims for Utility Model Registration] 1. A handle rotatably supported by a frame, an intermediate link connected to the handle, and a handle connected to the intermediate link with one end always being locked to the catch. A holding link that presses the movable contact at the end side to hold it in contact with the fixed contact, and a tripping device that releases the holding link from the catch when an overcurrent is detected, and the handle When the movable contact is operated from the closed position to the open position and the tripping device releases the holding link from the catch, the movable contact is released from the pressure from the holding link and is separated from the fixed contact. In the circuit breaker and disconnector, a tension spring is stretched between the frame and the intermediate link to hold the handle in the middle between the two opening and closing positions when the movable contact is opened by the operation of the tripping device. A circuit breaker characterized by: 2. The frame is provided with a protrusion corresponding to the other end of the presser link, and when the handle is operated from the trip position to the open position, the presser link contacts the protrusion and rotates around the protrusion. A circuit breaker according to claim 1, which is relatable to a catch. 3. The circuit breaker and circuit breaker according to claim 2 of the utility model registration, characterized in that the frame side of the tension spring is hung on a protruding piece of the frame.
