Allen Bradley 150-C251NCD SMC-3 Soft Starter – 75kW (251A) 200–600V, 3-Phase, 100–240V AC Control, Open Type Motor Controller

The Allen Bradley 150-C251NCD is a heavy-duty SMC-3 soft starter designed to deliver smooth, controlled motor acceleration and deceleration in demanding industrial environments. With a 251A operating current rating and compatibility with 200–600V 3-phase power systems, this model supports motors up to 75kW at 400V — reducing inrush current, mechanical shock, and long-term equipment wear.

Equipped with a 100–240V AC control supply, 3-wire start/stop interface, and integrated electronic motor overload protection, the 150-C251NCD is ideal for pumps, conveyors, compressors, blowers, agitators, and continuous-process systems requiring high reliability and operational consistency.
