The invention relates to an intelligent electric leakage protection plug, characterized by comprising a Schmidt electric field induction control circuit, a fault current induction circuit, a test circuit, a trip, a relay and a switch driving circuit, wherein a metal induction probe of the Schmidt electric field induction control circuit approaches the input end Y1 of a ground wire E, and the output ends Y2 and Y3 of the ground wire E are respectively electrically connected with two ends of a test switch of the test circuit; a first zero sequence current mutual inductor of the fault current induction circuit is sleeved on the ground wire E, and a second zero sequence current mutual inductor is sleeved on a null line N and a hot wire L; one end of each of three groups of normally-open contacts of the relay is respectively connected to the ground wire E, the null line N and the hot wire L of an urban alternating current, while the other end is respectively connected to an output load end; and the output end of the switch driving circuit is electrically connected with a trip coil of the trip via a rectifier diode. The intelligent electric leakage protection plug has the advantages of immediately and simultaneously cutting off the three-phase power supply circuit of the null line, the hot wire and the ground wire in any special electric leakage fault, and ensuring human safety.
