Allen-Bradley 150-C85NBR Three-Phase Soft Starter

Allen‑Bradley 150‑C85NBR is an open‑type SMC‑3 soft starter for three‑phase motors, rated for 85 A and designed to run on 200–460 V AC input. It uses 3‑wire wiring with a 24 V AC/DC control circuit (ND3W) to provide a controlled voltage ramp during start, reducing inrush current and mechanical stress on the motor. This 50/60 Hz capable controller sits in the SMC‑3 family and delivers soft‑start functionality in a compact, non‑enclosed form factor suitable for panel or device mounting, with built‑in protection features typical of Allen‑Bradley motor controllers. The model is specified for 3‑phase operation and is commonly used to start loads such as pumps, fans, conveyors, and compressors where smoother acceleration and electrical demand management are important.
