Allen-Bradley 150-C25NBR Soft Starter 25A 3PH

Allen-Bradley 150-C25NBR is a 3-wire SMC-3 soft starter for three-phase induction motors, delivering a controlled start that limits inrush current and reduces mechanical stress on drive trains. It handles motors up to 25 A and supports 200–480 V AC three-phase service, with a 24 V AC/DC control circuit for start/stop signaling. The current range is specified as 8.3–25 A, enabling compatibility with motors in the roughly 9–25 A class, and it provides selectable start times (2, 5, 10, 15, 20, 25, or 30 s) to tailor acceleration to load conditions. In typical installations, it is used in control panels for conveyors, pumps, compressors, and fans where smooth starting is important. The 150-C25NBR is part of Rockwell Automation’s SMC-3 family and has a nominal power rating around 11 kW at common voltages.
