Abstract
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.
