    摘要： In an exemplary embodiment of the invention, a locking mechanism comprising a blocking member sized to fit within the elongated slot through which a circuit breaker handle extends is disclosed. The blocking member may be seated adjacent the circuit breaker handle within the elongated slot and may snap or otherwise be locked into place to prevent the circuit breaker handle from moving within the slot. Thus, if the blocking member is placed within the elongated slot when the circuit breaker handle is in an OFF position, then the circuit breaker handle will be locked in the OFF position. The blocking member can be converted for locking the circuit breaker handle in an ON position. Then, when the blocking member is placed within the elongated slot when the circuit breaker handle is in an ON position, then the circuit breaker handle will be locked in the ON position. Once the blocking member is made for use in locking the circuit breaker in an ON condition, it cannot be converted back for use as a blocking member for locking the circuit breaker handle in an OFF position.

    摘要翻译： 在本发明的示例性实施例中，公开了一种锁定机构，其包括阻挡构件，该阻挡构件的尺寸被设计成配合在延伸的断路器延伸的细长槽中。 阻挡构件可以在细长槽内的断路器手柄附近安置，并且可以卡扣或以其他方式锁定到位以防止断路器手柄在槽内移动。 因此，当断路器手柄处于断开位置时，如果阻挡构件被放置在细长槽内，则断路器手柄将被锁定在OFF位置。 可以将阻挡构件转换成将断路器手柄锁定在ON位置。 然后，当断路器手柄处于ON位置时，当阻挡构件放置在细长槽内时，断路器手柄将被锁定在ON位置。 一旦阻塞构件用于将断路器锁定在接通状态，则不能将其转换回用作用于将断路器手柄锁定在OFF位置的阻挡构件。

    摘要： The draw out mechanism includes a crank, screw, collar and cam, which operate such that as the crank rotates, the collar translates along the screw. The movement of the pin disposed in the slot, rotates the cam as viewed about a axis of rotation. As the cam rotates about the axis of rotation, the pin moves within slot causing mobile side plates to move toward the front or back of the draw-out unit. A circuit breaker is connected to side plate and is positioned in CONNECT, DISCONNECT, and TEST positions by motion of the side plate. An indicator provides visual indication of the breaker's position. A locking system locks the draw-out mechanism in the DISCONNECT position.

    摘要： The invention relates to a locking device mounted directly on a circuit breaker and configured for mounting different locks. The locking device includes a yoke member, a slider member, a handle block and a lock. When the locking device is locked, the handle block abuts the operating handle in an engaged position corresponding to the operating handle in the ON or OFF position. Thus, the locking device locks the circuit breaker in the OFF position or the ON position. The locking device may further comprise a base member disposed between the yoke member and the housing. When it is desired to lock the circuit breaker in the on position, the base member is adapted to cover the push-to-trip button on the housing.
