Allen-Bradley 1492-CB2H150 Two-Pole Circuit Breaker

Allen-Bradley 1492-CB2H150 is a Series C, two-pole energy-limiting circuit breaker designed for DIN-rail mounting in industrial control panels. This 15 A device interrupts both poles of a 480Y/277 VAC, single-phase supply, and carries a 65 VDC maximum rating for DC circuits, making it suitable for mixed AC/DC panels. The Ser C model is part of the 1492 Energy Limiting Circuit Breakers family and is commonly used as a manual motor controller and supplementary protector in control circuitry, providing reliable overcurrent protection in compact DIN-rail enclosures. It is UL 508 and CSA approved, and the unit weighs about 0.60 lb, aligning with typical DIN-rail breakers of this class. The 1492-CB2H150 is documented as discontinued by the manufacturer as of November 30, 2007, so current availability is generally via surplus or distributor listings. This combination of 2-pole construction, 15 A rating, DIN-rail compatibility, and a 480Y/277 VAC single-phase rating makes it a targeted fit for panel boards that require space-efficient overcurrent protection for small to mid-range motor control and related control circuits in both new installations and legacy systems.
