Claims

[Scope of utility model registration request]

A contact device inserted into the main circuit, a latching device that holds the contact device in a closed state in a latched state that accumulates force in the direction of opening the contact device, and a latching device that is activated when an overcurrent passes through the main circuit. A trip device for releasing the latched state of the contact device and opening the contact device by the above-mentioned force is housed in the casing, and an operation button for setting the latching device to the latched state is inserted into the casing so as to be movable forward and backward. In the device, the contact device includes a first terminal plate having a first fixed contact, a frame made of a conductive material and having a second fixed contact, and a pair of movable contacts that come into contact with and separate from both fixed contacts. The latch device is rotatably attached to a rotating shaft attached to the frame, and one end of the movable contact is insulated from the frame at a position different from the movable contact. The tripping device has a latch link made of an insulating material that holds the movable contact and a latch spring that biases the latch link in a direction that separates the movable contact from the fixed contact. A bimetal plate with a locking part that engages with the latch link in the accumulated state, and a latch link and the bimetal plate that heat the bimetal plate when inserted into the main circuit and an overcurrent passes through the main circuit to engage the latch link and the bimetal plate. An overcurrent protection device comprising a resistance heater that releases the state, and a positioning rib protruding from the inner circumferential surface of the casing at a proper position to serve as a reference for the placement position of the resistance heater with respect to the bimetal plate.
