Allen-Bradley 150-C43NBR Smart Motor Controller

Allen-Bradley 150-C43NBR SMC-3 Smart Motor Controller is an open-type, three-phase soft-start starter designed for direct-to-line starting of standard induction motors. It accepts 200–460 VAC three-phase power (50/60 Hz) and uses 24 V AC/DC control power, with a 43 A current rating suitable for a range of motors in industrial panels. As part of the SMC-3 family, it provides built-in soft-start sequencing to limit inrush current and minimize mechanical stress during motor start, helping extend motor life and improve drive system reliability. The 150-C43NBR is intended for panel-mounted or open installation and is compatible with standard Allen-Bradley control architectures, enabling straightforward integration into existing control schemes that rely on discrete control signals to start and stop the motor. With its compact open-frame design and robust solid-state switching, this device supports smooth, controlled motor starts in applications such as conveyors, pumps, fans, and other equipment where reliable, energy-conscious motor control is desired.
