description The utility model discloses an integrated three-phase electricity leakage protector, comprising a current transformer and a power circuit. The utility model is characterized in that an integrated amplifying circuit is connected with the current transformer and outputs a signal to a voltage comparing circuit to compare with a signal generated by a reference voltage generating circuit; an executive circuit is connected with the voltage comparing circuit and drives a relay to generate a corresponding action; the executive circuit is connected with a delay circuit and connected with one terminal of a novel reclosing circuit, and the other terminal of the reclosing circuit is connected with the voltage comparing circuit. The utility model has the advantages of simple structure, low cost, convenient operation, increase of safety and reliability of the power supply and convenient debugging.
