The utility model discloses an electric leakage circuit breaker capable of replacing an electric leakage module on line, comprising a bearing frame and a circuit breaker structure, the surface of thecircuit breaker structure is movably connected with the inner cavity of the bearing frame, the top of the circuit breaker structure is in threaded connection with a conductive bolt, and the surface ofthe conductive bolt is fixedly connected with a conductive voltage sheet. The bottom end of the conductive bolt penetrates through the top of the circuit breaker structure and extends to an inner cavity of the circuit breaker structure, and the inner cavity of the circuit breaker structure is fixedly connected with a partition plate. According to the residual-current circuit breaker capable of replacing the residual-current module on line, when one circuit breaker structure cannot be used, the electric push rod is controlled to move through the single chip microcomputer, on-off of the conductive block and a circuit ca
