Allen-Bradley 150-F361NBD Smart Motor Controller

Allen-Bradley 150-F361NBD is an Open Smart Motor Controller in the SMC-Flex family from Rockwell Automation, designed to provide a controlled ramp and soft-start for large three-phase motors in open-drive installations. It accepts 200–480 V AC three-phase input and uses a 24 V AC/DC control supply, delivering a continuous current rating of 361 A and enabling motor sizes up to 150–300 HP at 460 V AC, depending on configuration. The 150-F361NBD variant includes a braking-control option for controlled stopping, and the open-smart controller architecture is intended for field installation with compatible, non-enclosed setups. As part of the SMC-Flex line, this device supports reliable soft-start for high-power motors, helping manage starting current and mechanical stress during startup.
