Allen-Bradley 1492-CB2H005 2-Pole Circuit Breaker

Allen-Bradley 1492-CB2H005 is a two-pole energy-limiting miniature circuit breaker designed as a supplementary protector for industrial control panels. It carries a rated current of 0.5 A and incorporates a magnetic trip mechanism with a range of 12 to 20 times the rated current for fast fault interruption, making it suitable for protecting small-control circuits in diverse automation environments. The unit is DIN-rail mountable and supports up to 480Y/277 VAC single-phase operation, with a maximum DC operating voltage of 65 V, enabling use in mixed AC/DC control applications. This 1492-CB family device provides a compact, two-pole footprint ideal for panel layouts where space is at a premium and precise current protection is required, with HP ratings cited around 1/6 HP in compatible circuits when wired for appropriate loads. When paired with other Allen-Bradley components, it helps achieve coordinated protection across automation installations and clear, reliable circuit isolation within control cabinets.
