    • 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。

    • A method for combining the operation of the electrical disconnecting safety switch of an electric motor within the motor's electrical terminal housing. This method of operation results in a single, compact housing directly mounted to the electric motor body which is used for both the safety disconnect function as well as the termination point for the incoming power leads and the motor wire taps. This method of operation may be employed for single phase and three phase alternating current motors as well as commonly wired direct current motors. The method further provides for a simple and economical way of mounting the device to a variety of motor frames with the use of appropriate adapter plates. The incorporated motor safety disconnect function is available in either of two configurations. The disconnect function may be operated as a rotary tumbler switch with an external rotary hand operator which allows a fully weatherproof design. The disconnect function may also be operated as a draw-out, or plug type, disconnecting switch which allows more economical manufacture.
    • 一种用于组合电动机电气端子壳体内的电动马达的电气断开安全开关的操作的方法。 这种操作方法导致直接安装到电动机主体的单个紧凑壳体,其用于安全断开功能以及用于输入电力线和电动机丝锥的终止点。 这种操作方法可以用于单相和三相交流电动机以及通用有线直流电动机。 该方法还提供了使用适当的适配器板将装置安装到各种电动机框架的简单且经济的方式。 并入的电机安全断开功能可用于两种配置之一。 断开功能可以作为具有外部旋转手动操作器的旋转开启开关来操作,这允许完全防风雨的设计。 断开功能也可以作为抽出式或插头式断开开关来操作,从而允许更经济的制造。
