Allen-Bradley 150-F201NBDB Smart Motor Controller

Allen-Bradley 150-F201NBDB Smart Motor Controller is an open-type SMC FLEX device for 3‑phase AC motors, delivering 201 A of current capacity and designed for 75–150 hp motors at 460 V (and 480 V) with a 50/60 Hz supply. It accepts a line voltage range of 200–460 V AC on the power side and uses a 100–240 V AC control circuit, enabling straightforward integration into standard control schemes. A standout feature is SMB (Smart Motor Braking) braking control, which provides motor braking without additional equipment, with braking current adjustable from 0 to 400% of the motor’s full‑load current rating. This open, non‑enclosed controller is intended for panel‑mounted installations and is part of the Rockwell Automation SMC FLEX family, suitable for applications such as pumps, fans, conveyors, and other equipment requiring controlled acceleration, deceleration, and braking. The 150-F201NBDB designation identifies this 201 A class within the SMC FLEX lineup, aligning with typical industrial motor control needs at mid‑high voltage and horsepower ranges.
