Allen-Bradley 150-C43NBR Smart Motor Controller

Allen-Bradley 150-C43NBR is a Smart Motor Controller in the SMC-3 family designed to provide solid-state control and protection for three-phase AC motors. The model is the 43 A variant, with a continuous motor current rating of 43 amperes, making it suitable for standard industrial induction motors in automation applications. As part of Rockwell Automation’s SMC-3 line, the 150-C43NBR supports typical 50/60 Hz three-phase power and is used to start, protect, and monitor motor operation in systems such as conveyors, pumps, and fans, where reliable current limiting and motor control are required. This controller is identified specifically by the 150-C43NBR designation within the SMC-3 family, aligning with Allen-Bradley’s line of smart motor controllers that are intended to simplify motor control while integrating with broader Rockwell hardware ecosystems.
