Allen Bradley 150-C251NCR SMC-3 Soft Starter – 75kW (251A) 200–600V, 3-Phase, 24V AC/DC Control, Open Type Motor Controller

The Allen Bradley 150-C251NCR is a high-capacity SMC-3 soft starter engineered for smooth motor acceleration and deceleration in heavy industrial applications. With a 251A continuous operating current rating and support for 200–600V 3-phase systems, this model can start motors up to 75kW at 400V, reducing electrical inrush and mechanical stress during startup and shutdown.

Equipped with a 24V AC/DC control interface, 3-wire control logic, and integrated electronic thermal overload protection, the 150-C251NCR is ideal for pumps, conveyors, crushers, mixers, blowers, and continuous-duty industrial process environments where long-term reliability is essential.
