    摘要： A handle of the operator is mounted on an external surface of a flange portion of a wall of an enclosure for a molded case circuit breaker and is drivingly connected to an operating handle of the circuit breaker. Interlock means prevent the operating handle of the circuit breaker from being turned to its ON position with a cover of the enclosure open, and the handle of the operator is normally positioned to mechanically interfere and thereby prevent the opening of the cover when the operating handle of the circuit breaker is in its ON position. The handle of the operator is pivotally mounted for limited movement relative to a drive shaft of the operator and can be locked in a single position to lock the circuit breaker handle in either its ON or OFF position. A true position indicator shows the position of the circuit breaker handle regardless of the position of the operator handle.

    摘要翻译： 操作者的手柄安装在用于模制外壳断路器的外壳的壁的凸缘部分的外表面上，并且驱动地连接到断路器的操作手柄。 联锁装置防止断路器的操作手柄转动到其开启位置，同时外壳的盖子打开，操作者的手柄通常被定位成机械地干涉，从而防止当操作手柄的操作手柄 断路器处于其ON位置。 操作者的手柄相对于操作者的驱动轴可枢转地被安装成有限的运动，并且可被锁定在单个位置以将断路器手柄锁定在其打开或关闭位置。 真正的位置指示器显示断路器手柄的位置，而不考虑操作手柄的位置。
