Abstract: A method and apparatus for a circuit breaker having an arc fault detection circuit, a ground fault detection circuit, a signal indicative of an arc fault in a corresponding pole of the circuit breaker; and a trip mechanism including a pair of separable contacts. The trip mechanism is in operable communication with the ground fault detection circuitry so than in response to receiving the signal from the ground fault detection circuitry, the arc fault detection circuitry causes the ground fault detection circuitry to generate a trip signal causing the trip mechanism to separate the pair of separable contacts.

Abstract: An arc fault/ground fault circuit interrupter for a power circuit includes a line terminal; a load terminal; and separable contacts electrically connected between the line and load terminals. An operating mechanism opens the separable contacts and has a closed position for closing the separable contacts. A trip mechanism cooperates with the operating mechanism to trip open the separable contacts. A ground fault protection circuit is operatively associated with the power circuit. An arc fault protection circuit is also operatively associated with the power circuit. A circuit tests the ground fault protection circuit, tests the arc fault protection circuit, and restores the operating mechanism to the closed position responsive to sequential activation of test and reset buttons.

Abstract: A protective device includes a test button for enabling a test signal for testing an operating condition of at least one of the device components, such as the sensor, detector, switch, solenoid and trip mechanism. The test button also enables a current through a resistor body which is affixed to a stationary part of the device. The resistor body keeps a lockout spring under tension. Failure of the test signal to operate the trip mechanism within a predetermined time interval causes the resistor body conducting said current to reach a predetermined temperature, wherein the resistor body ceases to hold a lockout spring, thereby permitting the lockout spring to move to a position which causes the set of interrupting contacts to remain permanently in a disconnected position.

Abstract: An electrical protective device that includes a reset mechanism uses a resistor body to act as a hold-off to a spring driven lockout for the reset mechanism. Upon the failure of an internal component of the protective device, the spring driven lockout mechanism is released by I2R thermal action which causes a resistor to burn in half, or in the alternative, to melt solder mounting the resistor, thereby eliminating the hold-off and locking out the reset mechanism.

Abstract: An arc fault circuit breaker assembled such that electrical interconnections, i.e., electrical connections between compartments, are made without disassembling any previously assembled compartment. The arc fault circuit breaker comprises housings having compartments within. Electrically connected components having interconnecting components, i.e., components which provide electrical interconnections between compartments, are disposed within the compartments. The housings are assembled together to enclose the compartments. Interconnecting components within an enclosed compartment extend through openings in the housings to provide electrical interconnections to the next compartment to be assembled. Therefore, no disassembly of the enclosed compartment is necessary to make the interconnections.

Abstract: A circuit breaker includes separable contacts, a latchable operating mechanism having a latch member, a bimetal and an arc fault trip assembly. The trip assembly includes a thermistor responsive to bimetal temperature, an amplifier having first and second inputs and an output, a first resistor electrically connected between a second bimetal terminal and the first amplifier input, a second resistor electrically connected in parallel with the thermistor, a third resistor electrically connected in series with that parallel combination, with that series combination being electrically connected between the first amplifier input and the amplifier output. The second amplifier input is referenced to the first bimetal terminal. The amplifier output has a voltage, which is compensated for the bimetal temperature coefficient. The trip assembly provides a trip signal as a function of compensated voltage. A solenoid responds to the trip signal and releases the latch member to trip the separable contacts open.

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 or if an open neutral condition exists.
