ABSTRACT:
An electrical contactor draw out tray has a movable frame and a stationary frame in which the movable frame carries the electrical components for an electrical feeder circuit. The stationary frame is preferably housed within a power distribution center and has input terminals for the incoming electrical power and output terminals for delivering electrical power to equipment operating on the feeder circuit. The movable frame carries the contactors that control the flow of electricity through the apparatus as well as the electrical components to monitor conditions of the apparatus and various parameters for the electricity carried therein to for conditions such as short circuits, overloads, ground faults, overvoltages and undervoltages. A disconnect mechanism locks the movable frame relative the stationary frame and provides a primary means for disengaging electrical flow through the apparatus.
