Service & Applications The Allen-Bradley 150-C201NBR is a high-capacity smart motor controller from the globally recognized SMC-3 product family, specifically designed for heavy-duty three-phase asynchronous motor regulations. This open-type industrial soft starter is capable of managing continuous currents up to 201A in standard line configurations and up to 348A when utilized within inside-delta networks. It features integrated solid-state electronic motor overload protections alongside an internal bypass configuration, which drastically minimizes heat dissipation (retaining a steady state of 129W) once the motor reaches full running speed. Equipped with configurable options for soft start ramp times, soft stop deceleration controls, current limiting, and selectable kick-starts, it serves as a crucial component for power systems in wastewater handling plants, chemical processing extraction pumps, heavy conveyor aggregates, and large-scale ventilation blowers.
