1. A leakage current detection interrupter, comprising:

  • (i) a movable assembly housing having a first side surface and an opposite, second side surface, and a body defined therebetween, wherein the body defines two vertical openings on the first side surface and the second surface;

    (ii) a first fixed contact holder having a first fixed contact point, and a second fixed contact holder having a second fixed contact point;

    (iii) a first movable contact holder and a second movable contact holder, each having a fixed end attached to the movable assembly housing and a movable end, wherein the first movable end has a first movable contact arranged for contacting the first fixed contact, the second movable end has a second movable contact arranged for contacting the second fixed contact;

    (iv) a movable assembly that moves between a first position in which each fixed contact makes contact with the respective movable contact and a second position in which the fixed contacts are separated from the movable contacts;

    (v) a resetting component having a first end accessible to a user for resetting the leakage current detection interrupter and a second end with a tapered tip and a notch, which, when the movable assembly is in the first position, is engaged with the movable assembly;

    (vi) a resetting component spring which releases the resetting component and disengage the movable assembly;

    (vii) an electromagnetic tripping component, which, when energized, which is responsive to a fault condition, causes the movable assembly to be in the second position from the first position, thereby causing the resetting component to disengage the movable assembly;

    (viii) an leakage current protection circuit assembled on a printed circuit board for detecting the fault condition, wherein the leakage current protection circuit comprises a first input LI-L, a second input LI-N, a third input LI-G, a first out put LO-P, a second output LO-N and a third output LO-G, wherein the leakage current protection circuit is capable of detecting a fault condition and energizing the electromagnetic tripping component to cause resetting component to disengage the movable assembly in responsive to the fault condition; and

    (ix) a set of three electrical wires to an appliance, wherein a first wire connects the first input LI-L to the first output LO-P, a second wire connects the second input LI-N to the second output LO-N, and a third wire connects the third input LI-G to the third output LO-G of the leakage current detection interrupter, and wherein the first wire and the second wire are protected by a plurality of protective shields.
