Leakage current detection interrupter with fire protection means
First Claim
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 second fixed contact, the second movable end has a second movable contact arranged for contacting the first 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; and
(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, a second input, a third input, a first output, a second output and a third output, 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.

Abstract
A leakage current detection interrupter with fire protection means, comprising: (i) a leakage current protection circuit, (ii) an electrical cord with metallic fire shields, and (iii) a fire protection circuit, wherein, in operation, the leakage current protection circuit and the fire protection circuit detect a fault condition including a leakage current, a ground fault and a fire hazard, and disconnect the source of electricity from the at least one user accessible load when leakage current, ground fault or fire hazard is detected. The electrical cord with metallic fire shields, the fire protection circuit, and the indicator circuit can be combined with any ground fault circuit interrupter, arc fault circuit interrupter, immerse detection circuit interrupter, appliance leakage current interrupter and electronic leakage current interrupter.
