Challenger CHMP250W5 Molded Case Circuit Breaker

Challenger CHMP250W5 Molded Case Circuit Breaker is a 3‑pole, 250 A motor circuit protector rated for 600 V AC, built in a molded‑case frame for reliable protection of 3‑phase motor circuits. In Eaton’s legacy catalogs this device appears as HMCP250W5 in the Series C, J‑frame family, and is designed for instantaneous magnetic protection only (I) with a magnetic trip range of about 1250–2500 A and standard line‑ and load‑side lug terminals. This molded‑case breaker is intended for motor protection and feeder protection in industrial control applications up to 250 A, commonly used to safeguard motors, conveyors, pumps, and fans from short‑circuit and overload events in 600 V systems. The CHMP250W5/MHCP250W5 lineage reflects Challenger’s historical branding that transitioned into Eaton’s catalog, offering a cross‑reference path for legacy equipment while delivering the same essential protection characteristics for 3‑phase, 600 V service.
