摘要： A circuit interrupter which comprises, in a compartment defined in an electrically insulating housing, a pair of separable contacts defining, when separated, an arcing region therebetween, and an operating mechanism, including a tripping unit and an operating handle, for opening and closing the separable contacts. The housing which includes an electrically insulating bottom wall has a gas exhaust passage having an inlet opening in the inner surface of the housing. The inlet of the gas exhaust passage is located in the bottom wall at a position effective for exhausting an arced gas generated in the arcing region without contacting the operating mechanism.

摘要： A drawer-type circuit breaker of the type adapted to be disposed in an engaged and disengaged position within a housing and a disengaged position outside the housing on extendable support rails is provided with latches which will prevent the extension of the guide rails until the circuit breaker is moved from the engaged position to the disengaged position within the housing. The movement of the circuit breaker to the disengaged position operates the latches to permit extension of the support rails while still preventing movement of the circuit breaker onto the support rails. Movement of the support rails to the fully extended position allows the latches to be released by movement of the circuit breaker to allow the circuit breaker to be withdrawn out of the housing onto the support rails. Actuating levers for engaging and disengaging the circuit breaker are provided on opposite sides of the circuit breaker for movement in respective slots and notches to smoothly and efficiently carry out the engaging and disengaging operation while preventing undesirable vertical movement of the circuit breaker relative to the housing.

摘要： A terminal connecting device has a plurality of movable contacts which are biased toward each other by springs to an extent limited by a spacer carried by the frame. The device is easily assembly by fitting shafts through bores in the contacts and using spring holders inserted between pairs of contacts and locked by wedges to exert a biasing force urging opposed contacts together. The shafts are held by support and frame members having open recesses, as opposed to bores, therein.

摘要： A circuit interrupter comprises a housing including a housing wall, an interrupting mechanism including a pair of separable contacts and an operating mechanism, and an optional accessory unit used in connection with an opening operation of the interrupting mechanism. The optional accessory unit may be a unit which includes a movable member operable in connection with the opening operation of the interrupting mechanism, such as an alarm switch, an auxiliary switch, a voltage trip device or an under voltage trip device. The optional accessory unit may be a connecting terminal block connectable between an external circuit and the circuit interrupter. The housing has formed in the outer surface thereof a receptacle cavity for receiving therein the optional accessory unit. When the unit is received in the cavity, no substantial portion of the unit projects from the housing. A fastening means comprises a slider, a guide rail engaging the slider for allowing a sliding movement of the optional accessory unit only in the direction of extension of the guide rail, and a screw for securing the optional accessory unit to the housing wall.

摘要： An arc-suppressing apparatus for a circuit breaker has a pair of side plates having a plurality of first and second grooves formed therein, the second grooves being shallower than the first grooves and extending linearly from the ends of the first grooves to an end of each of the side plates. The side plates are separated by a spacing strut and loosely connected by a bolt and nut so that a space exists between the plates which is large enough to allow a plurality of grids to slide along the second grooves into the first grooves. Thereafter, the nut and bolt are tightened to firmly secure the grids in the first grooves.
