Allen-Bradley 1492-CB3G250 3 Pole Circuit Breaker

Allen-Bradley 1492-CB3G250 is a three‑pole energy‑limiting miniature circuit breaker (MCB) designed for DIN‑rail mounting in control panels. Rated 25 A, this Series C device uses a G‑trip inductive characteristic with a magnetic trip range of 6–10× the rated current to quickly interrupt faults on a three‑phase circuit, making it well‑suited for inductive motor loads. As part of the 1492‑CB family, it carries UL 508 and CSA approvals and is commonly used in motor‑control centers and panel boards to protect feeders and motors; the 1492‑CB3G250 variant is associated with a 15 HP motor rating in typical configurations. The breaker protects all three phases simultaneously, ensuring coordinated disconnection in protective schemes for industrial automation equipment.
