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.
