Claims

[Scope of utility model registration request]

It is a small breaker that detects overcurrent or leakage and forcibly opens the fixed and movable contacts to interrupt the main circuit.The housing includes a surge absorber to absorb surges and a leakage detector to detect leakage. The base of the movable contact with the movable contact fixed to the tip is screwed to the bottom of the housing, and the base side of the movable contact is connected to the main circuit. In a small breaker to which lead wires of circuit elements are connected, a recess is formed on the bottom surface of the housing to which the lead wire inserted from the inside through an insertion hole can be wired, and a hole communicating with this recess is connected to the bottom surface of the housing. A movable contact structure for a small breaker, wherein a connecting piece is located in the hole to be connected to the lead wire formed integrally extending downward from the base of the movable contact.
