Abstract: A portable ground fault circuit breaker includes a main housing. An interior housing in which moving and static contacts are disposed is disposed inside the main housing and includes a base and a base cover. The static contacts are hung in the interior housing. The moving contacts are disposed on an unbalancing moving contact frame. A trip lock is disposed at one end of the moving contact frame and connected to a fasten lock fulfilling the separation and connection of the moving and static contacts. A lower portion of the fasten lock penetrates the base to abut on a tripping solenoid disposed at an exterior bottom of the base. The solenoid and a main control circuit on a circuit board fulfill an electrical connection. A simple structure, a small bulk, use convenience, and a humanized appearance design are the effects.
