Claims

[Scope of utility model registration request]

a handle rotatably supported by the main body case, an intermediate link connected to the handle, and a catch rotatably supported by the main body case;
A movable contact is connected to the intermediate link, and one end is always locked to the catch, and when the handle is in the closed position, the other end presses the movable contact to keep it in contact with the fixed contact. a presser link, a tripping device that releases the locking of the presser link by the catch when an overcurrent is detected, and a movable contact that is stretched between the main body case and the intermediate link and is operated by the tripping device. a tension spring for positioning the handle in a trip position intermediate between an open position and a closed position when the handle is separated from a fixed contact.
