Abstract

The invention provides a leakage circuit breaker, comprising a shell and a control circuit board arranged in the shell. A pair of elastic moving contact bridge legs, a returning mechanism, a tripping mechanism, a testing mechanism and an output connection lug connected with an output power line are mounted on the control circuit board; the tripping mechanism comprises a tripper, a lock and an electromagnetic element, wherein lift arms extending to both sides of the tripper are arranged below the moving contact bridge legs; a conductor piece is arranged between the control circuit board and the electromagnetic element; one end of the moving contact bridge leg and one end of the output connection lug respectively penetrates through the electromagnetic element and are connected to the control circuit board with the conductor sheet. The leakage circuit breaker can not only realize a normal leakage protection function, but also realize functions of ground abnormality protection, reverse connection protection and power line protection at the same time.
