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 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.

摘要： A field configurable contactor is disclosed. The contactor preferably includes a plurality of spaces adapted to receive any number, up to its limit, of contact modules. Each contact module preferably includes a pair of contacts and a spring biased cam follower which opens and closes the contact pair when a cam profile of the contactor moves according to energization or de-energization of the contactor. The contact module can be either “normally open” or “normally closed” depending on its initial placement onto the contactor relative to the cam profile. A latch assembly in the contactor may hold the contactor mechanically during de-energization.
摘要翻译：公开了现场可配置接触器。接触器优选地包括适于接收任何数量的多个空间，直到其极限的接触模块。每个触点模块优选地包括一对触点和弹簧偏置凸轮从动件，当接触器的凸轮轮廓根据接触器的通电或断电而移动时，该凸轮随动件打开和关闭触点对。根据接触器相对于凸轮轮廓的初始位置，接触模块可以是“常开”或“常闭”。接触器中的闩锁组件可以在断电期间机械地保持接触器。
