Allen-Bradley 150-C19NBR Smart Motor Controller

Allen-Bradley 150-C19NBR Smart Motor Controller is an SMC-3 soft-start device for three-phase induction motors, rated for 19 A at 480 V AC and designed for 50/60 Hz power with a 24 V AC/DC control circuit. As part of the SMC-3 family, it provides a controlled ramp and current limit to reduce inrush currents and mechanical stress during motor startup, helping protect both the motor and drive system. This 150-C19NBR is intended for industrial automation applications where reliable soft-start operation is required, such as conveyors, fans, pumps, and other three-phase loads. Its 24 V control power enables integration with common PLC control schemes and standard control wiring, while the 19 A nominal rating and 480 V three-phase input specify the upper bound of motor size and supply it supports. The device is a Rockwell Automation Smart Motor Controller that complements automation architectures seeking smoother motor starts with straightforward installation and operation.
