    • This apparatus incorporates an electric motor disconnecting safety switch within the motor's electrical terminal housing. This results in a single, compact device directly mounted to the electric motor body which is used for the safety disconnect as well as the termination point for the incoming power leads and the motor wire taps. The apparatus may be employed as a disconnecting device for single phase and three phase alternating current motors as well as various configurations of direct current motors. The apparatus further includes a simple and economical adapter plate mounting configuration which accommodates the device to a multiplicity of motor frames. This apparatus is used in three embodiments: the first being a rotary tumbler switching device with an external rotary hand operator; the second device being a draw-out disconnecting means; the third device including an integral motor starter which provides both disconnecting and motor controlling functions.
    • 该装置包括在电动机的电气端子壳体内的电动马达断开安全开关。 这导致直接安装到电动机主体的单个紧凑装置用于安全断开以及用于输入电源线和电动机丝锥的终端点。 该装置可以用作单相和三相交流电动机的断开装置以及直流电动机的各种配置。 该装置还包括简单经济的适配器板安装构造,其将装置容纳到多个电动机框架。 该装置用于三个实施例中:第一个是具有外部旋转手操作器的旋转开杯装置; 所述第二装置是抽出断开装置; 第三装置包括提供断开和电动机控制功能的整体式电动起动器。
