Variable depth circuit interrupter assembly with interlock

摘要

An improved circuit interrupter assembly provides enablement of an interlock feature for a circuit interrupter situated within a cabinet having an external handle for switching the circuit interrupter between ON and OFF conditions when the cabinet door is closed. The improved circuit interrupter assembly includes a motion transfer apparatus that provides such enablement of the interlock feature for cabinets of any of a variety of depths. The motion transfer apparatus includes a Bowden cable that extends between a first retention assembly situated at the door of the cabinet and a second retention assembly situated at the interlock feature of the circuit interrupter. The Bowden cable has a biased drive cable that extends between a pair of elements and which thus transfers the motion of the cabinet door in its closed position to enable cooperation with the interlock.

主权项

1. A circuit interrupter assembly structured to be connected with an electrical circuit and comprising:
a cabinet having a cabinet body and a door apparatus, the cabinet body having at least a first wall, the door apparatus being situated on the at least first wall and being movable between a closed position and an open position, the cabinet further having an interior region situated adjacent the at least first wall and adjacent the door apparatus in the closed position; a circuit interrupter situated substantially entirely within the interior region, the circuit interrupter being structured to be electrically connected with the electrical circuit and being further structured to control the flow of current through at least a portion of the electrical circuit, the circuit interrupter comprising a mechanism that is structured to be movable to switch the circuit interrupter between an OFF condition and an ON condition; a motion transfer apparatus structured to be cooperable with the door apparatus, the motion transfer apparatus comprising a transmission device that extends flexibly between the door apparatus in the closed position and the circuit interrupter, the transmission device being movable between a first position and a second position and being biased toward the first position, the transmission device being in the first position when the door apparatus is in its open position, the door engaging the transmission device and overcoming the bias to move the transmission device to the second position when the door apparatus is in its closed position; the mechanism comprising an interlock that is cooperable with the transmission device and which, in the first position of the transmission device, is structured to resist at least one of:
movement of the circuit interrupter from the ON condition to the OFF condition, andmovement of the circuit interrupter from the OFF condition to the ON condition; and the interlock in the second position of the transmission device being structured to permit movement of the circuit interrupter between the ON and OFF conditions.
