Abstract
The utility model relates to a socket ground fault circuit interrupter comprising a reset button, a resetting mechanism, a conductive assembly from a power input side to a load side, an electric leakage signal detecting circuit, and an electromagnetic tripping mechanism controlled by the electric leakage signal detecting circuit to operate. The resetting mechanism comprises a reset support and a support resetting mechanism. A pair of axially-extended blocking sheets are symmetrically disposed on an annular blocking plate on one end of an actuating coil rack in a reverse wiring protection apparatus, wherein the end of the actuating coil rack is close to an electromagnetic actuating support. The electromagnetic actuating support and a gap between conductive electrode sheets are arranged between the blocking sheets in a cooperation manner. The blocking sheets restrict the left and right movement of the electromagnetic actuating support. After the socket ground fault circuit interrupter is vibrated, contact accuracy between contacts can be guaranteed so that reliability is substantially increased.
