Allen-Bradley 150-A68NB Smart Motor Controller

Allen-Bradley 150-A68NB SMC-2 Smart Motor Controller is a compact, open-style controller for three-phase induction motors, rated for 380–480V AC input and a continuous current of 68 A, which equates to about 50 HP at 460 V. As a member of Rockwell Automation's SMC-2 family, it supports 50/60 Hz operation and is one of eight current-size options in the series (5, 9, 16, 24, 35, 54, 68, 97 A), with 150-A68NB representing the 68 A class. The device is designed for open-panel installations and integrates with standard SMC-2 wiring schemes for motor management, protection, and control within typical industrial automation architectures. Common applications include conveyors, pumps, fans, and other equipment driven by medium-size three-phase motors, where reliable motor starting and current control are important. With a 68 A rating and 50 HP specification, this controller is well-suited for mid-range drives in manufacturing, packaging, and processing environments using 3-phase power at around 460 V.
