Allen Bradley 150-C317NBR SMC-3 Soft Starter – 90kW (317A) 200–480V, 3-Phase, 24V AC/DC Control, Open Type Motor Controller

The Allen Bradley 150-C317NBR is a high-capacity SMC-3 soft starter engineered for smooth, controlled acceleration and deceleration of large industrial motors. With a robust 317A continuous current rating and compatibility with 200–480V 3-phase supply systems, this unit supports motors up to 90kW at 400V, significantly reducing mechanical stress and high inrush current during motor startup.

Built with a 24V AC/DC control input, 3-wire Start/Stop logic, and integrated electronic thermal overload protection, the 150-C317NBR is ideal for demanding applications including pumping stations, conveyors, crushers, mixers, industrial fans, and heavy process-driven machinery requiring continuous, reliable operation.
