Allen-Bradley 150-F43NBR Smart Motor Controller

Allen‑Bradley 150‑F43NBR is an Open‑frame SMC‑Flex Smart Motor Controller from Rockwell Automation that starts and protects medium‑sized motors with a 43 A rating. The open, solid‑state controller supports 200–480 V AC line voltage and uses 24 V AC/DC for control power, enabling straightforward integration into standard industrial control panels. It is rated for 7.5–30 HP when powered from 460 V AC, making it suitable for mid‑range applications that require soft‑start and motor protection in equipment like machine tools, conveyors, and packaging lines. As part of the SMC‑Flex family, the 150‑F43NBR emphasizes compact, open‑frame motor control with built‑in protection features and the ability to handle higher inrush when starting, delivering reliable, resistor‑free acceleration for three‑phase motors in demanding environments.
