Allen-Bradley 1492-CB3G120 Manual Motor Controller

Allen-Bradley 1492-CB3G120 Manual Motor Controller is a three-pole disconnect device that combines manual motor control with protective function in Allen-Bradley’s Bulletin 1492-CB family. The G120 variant provides a 12 A current rating with a magnetic trip intended for inductive loads, making it suitable for three‑phase motor circuits. It is configured for voltages common in North American power systems, including 480 VAC line-to-line and 277 VAC line-to-neutral, and is designed for DIN rail mounting in compatible control panels. As a Manual Motor Controller with supplementary protection, it serves as a compact motor disconnect in applications such as conveyors, pumps, and fans, enabling local on/off control while delivering overcurrent protection within a single, standardized 3‑pole package.
