摘要: A circuit interrupter including a drawout unit mounted within a sealable enclosure and operable between engaged and disengaged positions. A removable conductive safety barrier at ground potential is mounted on the front of the drawout unit and prevents any human contact with components at high potential. An interlock prevents removal of the safety barrier unless the drawout unit is in the fully levered out position. A hinged plate is operated by replacement of the safety barrier to allow the drawout unit to be operated to the engaged position.

摘要: A handle mounted externally on the door of a sealed enclosure operates a mechanism on the inner side of the door which controls the opening and closing of a circuit breaker located within the enclosure. The handle has a detented OPEN and AUTO position and a spring returned CLOSE position. When the handle is in the OPEN position an extensor assembly moves a contact member perpendicularly away from the inner surface of the door to operate a mechanical trip plate of the associated circuit breaker. When the handle is moved to the CLOSE or AUTO position a bumper member is moved by the mechanism in a direction parallel to the inner surface of the door to selectively activate either of two switches located on a switch bracket resiliently mounted upon the associated circuit breaker. The door can be hinged from either side. The handle can be padlocked in the OPEN or AUTO position but not in the CLOSE position.
