Allen-Bradley 1492-SPM2D250 Circuit Breaker

Allen-Bradley 1492-SPM2D250 is a two‑pole miniature circuit breaker designed as a supplementary protector (Bulletin 1492-SPM). It carries a 25 A rating, uses a Type D trip curve, and has no neutral terminal. The device supports 480Y/277 VAC circuits and up to 96 VDC, and it provides a 10 kA short‑circuit breaking capacity to withstand fault currents. Listed to UL 1077, this 2‑pole model is part of the 1492‑SPM family and is intended for installation in electrical control panels and distribution enclosures that require an additional protective device alongside primary protection. As a supplementary protector, it complements main overcurrent devices in multi‑device protection schemes and is suitable for circuits where a dedicated downstream protection element is warranted.
