    摘要: An improved electrical interrupter apparatus includes a stationary contact and a movable contact within an enclosed region, with the movable contact being operatively connected with a drive unit that employs a pull-to-close mechanism to engage the movable contact with the stationary contact. When the contacts are desired to be closed, the drive unit applies a tensile force to an elongated rod that extends between the drive unit and a crank mechanism, which converts the tensile force in the rod into a compressive force applied to the movable contact.

    摘要: A compact power circuit breaker has a molded insulative casing providing the structural support and electrical isolation for the pole mechanisms mounted in cavities in the casing and the operating mechanism mounted to the front of the casing. A grounded barrier between the pole mechanisms and the operating mechanism protects the operator actuating push buttons controlling the operating mechanism and accessible through a molded insulative cover. Preferably, the grounded barrier is sandwiched between a rear section of the molded casing containing the pole cavities and a forward section to which the operating mechanism is secured. The grounded barrier is connected to an electrically conductive pan extending under the molded insulative casing which also houses electrically grounded linkages coupling the operating mechanism to the vacuum interrupters of the pole mechanisms. A vented air gap between the rear section of the molded insulative casing and the grounded barrier minimizes erosion of the molded insulative casing in the event of an arc penetrating the casings to the grounded barrier.
