Challenger LP-9473 Industrial Circuit Breaker

Challenger LP-9473 is a three-pole circuit breaker switch designated Type NEF, with a 480 VAC operating rating and 250 VDC compatibility noted in the model description, identifying it as a high-capacity protective device designed for multi-wire AC systems in industrial power distribution gear. As a three-pole unit, it interrupts fault currents across all conductors in a three-phase circuit, enabling rapid disconnection in the event of overloads or short circuits and helping to safeguard connected equipment, wiring, and panel infrastructure in environments where 480 VAC service is standard. The LP-9473 bears the NEF Type designation, indicating a listed three-pole protective device compatible with enclosures designed for three-pole configurations and rated for 480 VAC and 250 VDC. This combination—three-pole configuration, NEF designation, and dual voltage ratings—makes LP-9473 suitable for use in electrical systems where 480 VAC power is distributed with DC control circuits, subject to the manufacturer's listing and installation requirements.
