Challenger FCSS323R U Low Voltage Motor Contactor

Challenger FCSS323R U is a three-pole low-voltage motor contactor engineered to switch heavy three-phase motor loads, combining a robust 100 A main current rating with 240 V AC operation to handle demanding startup transients in commercial and light-industrial equipment. Its NN3R enclosure, a NEMA 3R-rated housing, provides protection from environmental exposure and is suitable for installations indoors or outdoors, enabling mounting in equipment rooms, weather-exposed locations, or outdoor units where a protective enclosure is required. With its FCSS323R U designation within the Challenger FCSS323R family, this unit represents a dedicated, compact solution for 3-pole motor control applications where a high-current switch is needed to reliably engage and disengage 3-phase motors, often in HVAC, pumping, and material-handling equipment.
