Allen-Bradley 1492-CB3G010 Supplementary Protector

Allen-Bradley 1492-CB3G010 Supplementary Protector is a three-pole miniature circuit breaker designed to protect motor-control circuits by providing overload and short-circuit protection in a compact, integrated package. Part of Rockwell Automation's Bulletin 1492-CB family, it combines a manual motor controller with a supplementary protector, enabling convenient control alongside reliable protection in a single device. Rated for 480 VAC operation and intended for three-phase systems, the unit carries a G-type trip curve (as indicated by the G in the model name) to suit motor and inductive loads. The exact device is identified by NE #204755, and the part number 1492-CB3G010 denotes the three-pole configuration with the 010 suffix in the model family. Typical applications include motor control centers, machine panels, and distribution boards where individual motor feeders require integrated protection with reset capability. This supplementary protector is designed for use in compatible Allen-Bradley control circuits and is commonly paired with other 1492-series components to form a compact, reliable protection solution in industrial automation installations.
