A leakage current protection plug includes a plug housing, a power supply cord, two copper legs embedded within the plug housing, a leakage current protection device composed of two main moving contacts. A reset button presses the moving contacts to contact the two copper legs, a winding assemble, an iron core, a circuit board assemble, an ZCT. Ends of moving contacts are arranged with contacts that conduct individually with the two copper legs upon coming into contact; the power supply cord, through the ZCT, is connected with the moving contacts; the output of the ZCT is connected with the input of the amplification circuit on the circuit board, while the output of the amplification circuit is connected with the winding assemble.
