The H breaking capacity code delivers 100 kA Icu at 220/240 V AC and 70 kA Icu at 380/415 V AC, both per IEC 60947-2 — that headroom means it clears high-fault currents on a distribution bus without upstream coordination issues. Mounts on a backplate in either horizontal or vertical orientation, flat on the back — no DIN-rail clip, so plan for bolted panel mounting. Front connections on both the upside and downside simplify bus-bar or cable routing in a distribution panel. The 4-pole layout with neutral on the left fits standard switchboard phase arrangements. IP40 front face and IK07 impact resistance are adequate for enclosed panel environments; keep the enclosure door closed during operation. ## Durability and environment Rated for 20,000 mechanical cycles and up to 20,000 electrical cycles at 440 V at half-rated current (10,000 at full rated current). The thermal memory holds the trip profile for 20 minutes before and after a trip event, so re-energizing a hot breaker doesn't nuisance-trip on a second overload.","metaTitle":"Schneider C25H42D250 ComPacT NSX250H, 250 A, 4P, 100 kA","metaDescription":"Schneider Electric C25H42D250 ComPacT NSX250H circuit breaker with MicroLogic 2.2 electronic trip unit, 250 A, 4P, 100 kA Icu at 240 V AC.
