Allen-Bradley 1492-CB2G500 Circuit Breaker

Allen-Bradley 1492-CB2G500 is a two-pole, DIN-rail-mounted miniature circuit breaker in the 1492 wiring system, rated for 50 A and designed to protect equipment on AC circuits up to 480 V and DC circuits up to 65 V. The G-trip variant indicates inductive-load protection, making it well-suited for motor starters and other inductive applications where reliable short-circuit and overload protection is required. This unit mounts on standard DIN rails in control panels and has an approximate weight of 1.0 lb, aligning with typical DIN-rail circuit breakers in industrial environments. As part of Allen-Bradley’s 1492 family, it serves as a manual motor controller and supplementary protector within industrial control systems. The 1492-CB2G500 is listed in catalog records as discontinued by the manufacturer, so current availability is generally limited to surplus or refurbished inventory from authorized distributors. With a 2-pole configuration and a 50 A rating, this model provides robust protection for AC mains up to 480 VAC in panel installations that require DIN-rail protection for two conductors.
