Allen-Bradley 150-C3NBD is an SMC-3 soft starter designed for 3-phase induction motors on 480 V systems; this open-type, 3-wire controller is rated for 3 A and accepts a 100-240 V AC control input, with 50/60 Hz operation and a starting duty of 350% to limit inrush current during motor startup. The unit features a normally open fault contact and is specified for 3-phase 480 V service in an open enclosure, enabling straightforward wiring to a PLC or control circuit. Typical applications include small conveyors, fans, and pumps where controlled acceleration and reduced mechanical stress are desired, without a drive or inverter.
