Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include a reset lock-out mechanism are provided. The reset lock-out mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open neutral condition exists.

Abstract: Resettable circuit interrupting devices using a center latch are provided. The circuit interrupting devices include those with a reset lockout, reverse wiring protection, and/or an independent trip portion.

Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include reverse wiring protection, and optionally an independent trip portions and/or a reset lockout portion are provided. The reverse wiring protection operates at both the line and load sides of the device so that in the event line side wiring to the device is improperly connected to the load side, fault protection for the device remains. The trip portion operates independently of a circuit interrupting portion used to break the electrical continuity in one or more conductive paths in the device. The reset lockout portion prevents the reestablishing of electrical continuity in open conductive paths if the circuit interrupting portion is non-operational, if an open neutral condition exists or if the device is reverse wired. Methods for ensuring a reset lock out state before shipment are provided.

Abstract: A ground fault circuit interrupter for a direct current (DC) system which can interrupt DC power connections to one or more loads when a fault is detected is disclosed herein. Specifically, the circuit interrupter includes a toroidal core having a winding wound around the core. An alternating current supply is coupled to the current sense winding. Source and return wires of an external DC current supply pass through the core, coupling the DC current supply to respective ends of an external DC load. A current imbalance between the source and return wires causes the core to saturate changing the impedance of the winding. The impedance change causes a fault signal to be generated and said fault signal is used to break the electrical connection between the external direct current supply and the external load.

Abstract: Resettable circuit interrupting devices, such as GFCI devices, that include an independent trip mechanism and a reset lockout mechanism are provided. The trip mechanism operates independently of a circuit interrupting mechanism used to break the connection, and the reset lockout mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism is non-operational or if an open neutral condition exists.

Abstract: The present invention is directed to current interrupting devices with overcurrent protection. In one embodiment, a ground fault circuit interrupter (GFCI) is disclosed having both ground fault and overcurrent protection. The GFCI has a current detection circuit that includes a switch connected across the load phase terminal and the line neutral terminal of the device. A comparator compares a predefined threshold voltage to a sensed voltage based on a current through the line and load neutral terminals of the device. If the sensed voltage exceeds the predefined threshold, the comparator causes the switch to conduct thereby tripping the device, disconnecting the load from the line terminals and preventing the overcurrent condition from causing damage to the device and/or load.

Abstract: A resettable circuit interrupting device such as a GFCI that is immune to the problem of reverse wiring and, therefore, has load-line terminals that can be interchangeably connected to either at least one load or to a power source. Regardless of how the load-line terminals are connected, the resettable circuit interrupting device operates properly and retains leakage current fault protection. The circuit interrupting device includes an interrupting portion disposed within the device configured to cause electrical discontinuity in either the phase and/or neutral conductive paths between the line side and the load side upon the occurrence of a leakage condition. A reset portion disposed at least partially within the device is configured to initially establish or, after the detection of a leakage current fault, reestablish electrical continuity between the load and the line.
