    摘要: A neutral pole for a multipole circuit breaker is disclosed. The circuit breaker includes a housing, a plurality of contact arms for opening and closing an electrical circuit, and an operating mechanism for driving the contact arms. The neutral pole includes a neutral housing, a conduction path within the neutral housing having a neutral arm arranged to open and close the conduction path, a bias spring configured to exert a first bias moment on the neutral arm when the conduction path is closed, a spring support configured to support the bias spring, a rotor pivotally arranged within the neutral housing and configured to displace the neutral arm and to open the conduction path, and a drive pin configured to couple the rotor to the multipole circuit breaker. The spring support is fixedly arranged at the neutral housing. The rotor is responsive to the opening and closing action of the operating mechanism of the multipole circuit breaker.

    摘要: A fire plate for receiving a bored in lock assembly and preventing passage of fire through a lock opening bored perpendicularly through a fire door. The fire plate is particularly adapted for use with integrated lock and latch assemblies that are designed for installation through a latch opening bored from an edge of the door into the lock opening. The latch opening has a diameter less than the lock opening and the fire plate blocks the space above and below the lock assembly in the lock opening to prevent the passage of smoke and fire through the lock opening. The fire plate includes two fire stop barriers that may be formed by bending from a sheet of spring steel and which preferably snap into engagement with the lock assembly as it is inserted from the latch opening into the lock opening.

    摘要: An apparatus for interrupting an electrical short circuit current in an electrical distribution system having a plurality of phases is disclosed. The apparatus includes a housing, a plurality of separable conduction paths, an operating mechanism in operable communication with the plurality of conduction paths, an electronic trip unit in signal communication with each of the plurality of conduction paths and in operable communication with the operating mechanism, and an electromagnetic trip unit in signal communication with each of the plurality of conduction paths and in operable communication with the operating mechanism. The electromagnetic trip unit is configured to be operably responsive to a first half-cycle waveform of the short circuit current prior to the electronic trip unit being operably responsive to a second multi-cycle waveform of the short circuit current.
