    • A handle assembly and an alignment member are mounted on a joining structure that fixedly joins a pair of circuit breakers together. A support assembly is mounted in a cassette that removably receives the circuit breakers and joining structure. The support assembly includes a support bar that is moveable between an inward position and an outward position and that provides vertical support to the joining structure and to the circuit breakers to resist sagging of the circuit breakers at the joining structure to facilitate alignment of the circuit breakers with the cassette and installation of the circuit breakers therein. The handle assembly includes a handle that is moveable between a retracted position and an extended position. A horizontal tensile force applied to the handle in the extended position is, in turn, equally applied to each of the circuit breakers to simultaneously disengage the circuit breakers from the stabs on the cassette and to resist the circuit breakers from binding up within the cassette during removal therefrom.
    • 手柄组件和对准构件安装在将一对断路器固定地连接在一起的接合结构上。 支撑组件安装在可拆卸地接收断路器和接合结构的盒中。 支撑组件包括支撑杆,该支撑杆可以在向内位置和向外位置之间移动,并且向连接结构和断路器提供垂直支撑以抵抗断路器在接合结构处的下垂,以便于断路器的对准 带有磁带和其中的断路器的安装。 手柄组件包括可在缩回位置和延伸位置之间移动的手柄。 在延伸位置施加到手柄的水平张力反过来同样地施加到每个断路器,以同时使断路器与盒上的刺针脱离,并且防止断路器在盒内装入 从中移除。
