Allen-Bradley 150-C9NBD Smart Motor Controller

The Allen-Bradley 150-C9NBD is an open-type SMC-3 Smart Motor Controller rated for 9 A, designed to start and protect 3‑phase motors in 380–460 V systems with a 50/60 Hz supply. This 3‑wire, open Type controller accepts control voltages of 100–240 V AC and provides integrated motor overload protection for compact open-panel installations. In 380/400/415/460 V configurations, line-connected motor currents range from 3 to 9 A, delta-connected currents from 5.1 to 16 A, with a motor power range of 2.2 to 7.5 kW; insulation is rated 600 V AC and dielectric withstand is 2500 V AC. The SMC-3 platform supports high fault currents up to 69 kA at 600 V and is intended for soft-start and motor-protection roles in industrial applications.
