    Abstract: A protection device protecting a load circuit by shutting off a power thereof depending on an estimated present temperature of a wire provided in the load circuit to connect a load. The protection device has a first temperature estimation device estimating a rising temperature of a conductor including the wire based on both a current in the conductor and thermal properties of the conductor, a second temperature estimation device estimating a falling temperature of the conductor based on the thermal properties, a third temperature estimation device estimating an arc-induced rising temperature of the conductor when arcing occurs in the conductor, and a fourth temperature estimation device estimating the present temperature of the conductor deduced from the above estimated temperatures. If the estimated temperature exceeds a predetermined allowable temperature, the protection device shut off the power of the load circuit.

    Abstract: An aircraft circuit breaker includes a housing having an opening, separable contacts, an operating mechanism structured to open and close the contacts, and a trip mechanism structured to cooperate with the operating mechanism to trip open the operating mechanism. The trip mechanism includes a first bimetal to trip open the operating mechanism responsive to a thermal fault, a second ambient compensation bimetal to compensate the first bimetal, and an arc fault trip circuit to trip open the operating mechanism responsive to an arc fault. An indicator includes an indicator portion and a leg disposed from the indicator portion. A spring biases the indicator portion. The second bimetal holds the leg of the indicator, thereby holding the indicator against the spring bias. The second bimetal releases the leg of the indicator responsive to the arc fault trip circuit and the arc fault, thereby releasing the indicator to the spring bias.

    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.

    Abstract: A circuit breaker includes a first lug and second and third acoustic lugs electrically connected to a power circuit. Separable contacts are electrically connected in series between the first lug and the second acoustic lug. An operating mechanism opens and closes the separable contacts. A first acoustic sensor is coupled to the second acoustic lug and senses a first acoustic signal from the second acoustic lug. A second acoustic sensor is coupled to the third acoustic lug and senses a second acoustic signal from the third acoustic lug. The first and second acoustic signals are operatively associated with a power circuit fault. A current sensor senses a current flowing between the first and second lugs. A circuit inputs the sensed acoustic signals and the sensed current and detects and distinguishes a parallel arc fault or a series arc fault from the sensed acoustic signals and the sensed current.

    Abstract: The present invention is directed to a protective device that includes a plurality of line terminals configured to be connected to an electrical distribution system, and a plurality of load terminals configured to be connected to a load. The device includes a fault detection circuit coupled to the plurality of line terminals and the plurality of load terminals. The fault detection circuit is configured to detect at least one fault in the electrical distribution system. A power interruption circuit couples the plurality of line terminals to the plurality of load terminals to thereby provide power to the load under normal operating conditions. The power interruption circuit also is coupled to the fault detection circuit, and configured to decouple the plurality of line terminals from the plurality of load terminals in response to the fault detection circuit detecting the at least one fault. A test circuit is coupled to the fault detection circuit and the power interruption circuit. The test circuit is configured to provide a simulated fault signal to the fault detection circuit in response to a user stimulus. An end-of-life indication circuit is coupled to the test circuit and the power interruption circuit. The end-of-life indication circuit provides the user with an end-of-life alarm indicator if the fault detection circuit fails to respond to the simulated fault signal within a predetermined period of time.
