Motor control center subunit having visible contact disconnection and method of manufacture
摘要：
A motor control center subunit includes a subunit housing configured to fit within a motor control center. The housing has a front panel. The motor control center subunit also includes a drive mechanism attached to the subunit housing. The drive mechanism is configured to control a plurality of line connectors to move between a retracted position and an extended position when the subunit housing is seated in the motor control center and the front panel of the subunit housing is in a closed position. A window is disposed in the front panel of the subunit housing and is positioned to provide a view of the plurality of line connectors.
摘要（中）：

马达控制中心子单元包括配置成装配在马达控制中心内的子单元壳体。 外壳有一个前面板。 电动机控制中心子单元还包括附接到子单元壳体的驱动机构。 驱动机构构造成当子单元壳体位于马达控制中心中并且子单元壳体的前面板处于关闭位置时，控制多个线连接器在缩回位置和延伸位置之间移动。 窗口设置在子单元壳体的前面板中并且被定位成提供多个线连接器的视图。
