Abstract
A removable contactor drawer including a transitional chamber receivable in a fixed casing. The transitional chamber including electrical components for an electrical feeder circuit. The fixed casing being designed to be mounted and used within a power distribution center and has input connectors for the incoming electrical power. Source power may be channeled through the electrical components via the fixed casing and delivered to a power outlet on a front face of the transitional chamber. The transitional chamber may optionally contain equipment to monitor and report operational faults within the contactor drawer. A front-mounted motor drive allows a remotely located operator to perform removal of the transitional chamber while under power, thus providing protection against the danger of arc flash.
