    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 multipole circuit breaker of a type with a mechanism pole having a switching mechanism in which adjacent poles are disposed in opposition to the mechanism pole with an interphase wall therebetween and each having an internal attachment such as an alarm switch or the like but no switching mechanism. A latch engages a cradle of the switching mechanism and is arranged to be actuated by an automatic tripping device. A supporting shaft rotatably supports the latch, an a lever fixed on the supporting shaft engages the cradle. Actuators are fixed on the supporting shaft so as to engage the internal attachment of the respect adjacent poles. The supporting shaft is made of metal. Insulating caps are inserted and fixed onto end portions of the supporting shaft, the supporting shaft passing at portions of the insulating caps through the interphase walls. The actuators are inserted and fixed onto the insulating caps.

    摘要： A circuit breaker having separable contacts and a releasable trip mechanism operable upon overcurrent conditions to automatically separate the contacts includes a moveable arm stop connected to the releasable mechanism for limiting travel of the moveable contact in the open circuit position. The moveable arm stop includes a cam portion having an extended surface to limit travel of the moveable contact and establish a first contact separation distance when the trip mechanism is latched, and a flat surface limiting travel of the moveable contact to establish a second, greater contact separation distance when the trip mechanism is released.

    摘要： A circuit breaker having a larger separation distance between a stationary contact 4 and a movable contact 6 in the automatic mode than in the manual mode. The pivot shaft 24 of a crank 13 is placed in a higher position than in a conventional circuit breaker, to thereby enable the arm 7 carrying the movable contact 6 to rotate through a greater angle. A stop plate 26 is provided to prevent the flex angle .theta. formed between a first link 11 and a second link 12 of a toggle mechanism 10 from becoming too small when the contacts are opened, which enables easy manual closure with the normal stroke of a switch handle 16 and avoids the need for a stronger spring 17.
