摘要： A circuit breaker comprises a housing containing a trip mechanism, a handle coupled to the trip mechanism and movable between on and off positions, and a lock-off mechanism capable of holding the handle in its off position. The lock-off mechanism includes a base member adapted to be mounted on the circuit breaker housing adjacent the movable handle. A slide is mounted on the base member for movement to an advanced position in which a portion of the slide projects into the path of movement of the breaker handle for engaging the handle and blocks movement of the handle from the “off” position to the “on” position. In the retracted position of the slide, the path of movement of the handle is unobstructed by the slide. A key-operated lock is also mounted on the base, and a lock shaft is coupled to the lock and mounted for movement to a locked position in which the shaft engages the slide when the slide is in its advanced position to block retracting movement of the slide, thereby locking the breaker handle in its “off” position. In the unlocked position of the lock shaft, movement of the slide is unobstructed by the shaft, but the slide interferes with advancing movement of the lock shaft, thereby preventing the lock shaft from moving to its advanced position.

摘要： A circuit breaker lock-off device is side-mounted to a circuit breaker case in a tenacious engagement. The lock-off device has a generally planar body carrying a lock-off arm pivotable in a plane parallel to the body to place an engagement tab extending therefrom into a position for preventing movement of the breaker handle without being physically attached to the breaker handle. The lock-off arm and the body further have complementary rings for accepting a padlock shackle in the locked off position. The invention allows a rugged lock-off accessory which is field installable and which can accommodate various breaker handle geometries.
摘要翻译：断路器锁定装置以坚固的接合方式安装到断路器壳体上。锁定装置具有一个大致平面的主体，该主体具有可在平行于主体的平面中枢转的锁定臂，以将从其延伸的接合突片放置在防止断路器手柄移动而不物理地附接到断路器手柄的位置。锁定臂和主体还具有用于接受处于锁定位置的挂锁钩环的互补环。本发明允许可现场安装并且可以适应各种断路器手柄几何形状的坚固的锁定附件。
