Allen-Bradley 1492-D1C100 Miniature Circuit Breaker

Allen-Bradley 1492-D1C100 is a DC high‑voltage miniature circuit breaker (MCB) from Rockwell Automation’s 1492‑D family. This 1‑pole device is rated for 10 A continuous current and uses Trip Curve C, providing overcurrent protection tailored for DC circuits. It is rated up to 500 V DC, with a breaking capacity up to 10 kA at 500 V DC, enabling fast isolation in fault conditions. Mounting is bolt‑on for compact panel integration, and the unit is UL‑listed and CSA‑certified under Bulletin 1492‑D specifications. As part of the 1492‑D line, it offers thermal‑magnetic protection with long‑time and instantaneous trip functions, making it suitable for DC power distribution in industrial control cabinets where reliable protection is required. The 1492‑D1C100 embodies a compact, single‑pole form factor that supports precise current protection while occupying minimal panel space in demanding DC environments.
