The invention provides a leakage breaker, which simplifies the electrical connection of a main circuit and a leakage detection circuit and is easy to assemble. The leakage breaker comprises a load side main circuit terminal connected with the main circuit, a current collector equipped on the power supply input end of a printed circuit board for carrying a control power supply circuit, and a helical spring equipped between the load side main circuit terminal and the current collector. By installing a main body cover, a circuit unit composed by clamping the printed circuit board, the helical spring and the current collector through a unit base and a unit cover presses the helical spring towards the direction of the load side main circuit terminal. Therefore, the two ends of the helical spring are respectively in contact with the current collector and the load side main circuit terminal. Then the printed circuit board is supplied with a control power supply from the load side main circuit terminal. |
