    摘要： A hybrid switch assembly for a circuit breaker assembly is provided. The circuit breaker assembly includes a housing assembly and an operating mechanism. The housing assembly defines a power electronic switch assembly cavity. A hybrid switch assembly includes a number of conductor assemblies, each conductor assembly including a movable conductor, and a stationary conductor. Further, each movable conductor is structured to move between an open, first position, wherein each movable conductor is spaced from and not in electrical communication with an associated stationary conductor, and a closed, second position, wherein each movable conductor is coupled to and in electrical communication with an associated stationary conductor. A number of the conductor assemblies further include a power electronic switch assembly. Each power electronic switch assembly includes an isolation contact assembly. Each isolation contact assembly is selectively coupled to, and in electronic communication with, the stationary conductor and the movable conductor.

    摘要： An electrical switching apparatus includes a transductor circuit that senses a direct current between an input terminal and an output terminal and outputs an alternating current proportional to the direct current. The electrical switching apparatus also includes a current sensor configured to sense an alternating current component of the direct current. The electrical switching apparatus further includes an alternating current electronic trip circuit including an arc fault detection circuit configured to detect an arc fault based on the sensed alternating current component. The alternating current electronic trip circuit is also configured to control pairs of separable contacts to trip open based on the alternating current output from the transductor circuit or the detected arc fault. The electrical switching apparatus also includes a power supply structured to provide direct current power to the alternating current electronic trip circuit.

    摘要： A circuit breaker includes first and second terminals, separable contacts, conductors electrically connecting the contacts between the terminals, and an operating mechanism to open and close the contacts. A current sensor senses current flowing through the contacts and outputs a current value. A number of temperature sensors output a number of temperature values corresponding to a number of the conductors. An electronic trip circuit cooperates with the operating mechanism to trip open the contacts, and includes a processor having a first input inputting the current value, a first routine inputting the current value from the first input and causing the operating mechanism to trip open the contacts responsive to over-current, a number of second inputs inputting the number of temperature values, and a second routine comparing the number of temperature values to a number of limits and causing the operating mechanism to trip open the contacts responsive to over-temperature.

    摘要： A debris barrier is for an electrical switching apparatus. The electrical switching apparatus includes separable contacts and an arc chute. The separable contacts generate debris when tripping open in response to an electrical fault. The arc chute has a plurality of splitter plates each having an edge portion and a distal portion located opposite and distal the edge portion. The debris barrier includes a first leg, a second leg, and a middle portion connecting the first leg and the second leg. The middle portion is coupled to one of the separable contacts. At least one of the first leg and the second leg has a first barrier portion and a second barrier portion extending therefrom. The first barrier portion is located proximate the distal portion. The second barrier portion extends from the first barrier portion toward the edge portion in order to redirect the debris toward the edge portion.
