Product details

The C25H42D250 is a Schneider Electric ComPacT NSX250H molded-case circuit breaker with a MicroLogic 2.2 electronic trip unit, rated 250 A at 40 °C across 4 poles. 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.

Frequently asked questions

How do I get current pricing and availability for C25H42D250?

Submit an RFQ through this listing. Availability and current pricing are confirmed at quote time through independent distribution channels.

What is the breaking capacity of C25H42D250 at 415 V?

The C25H42D250 delivers 70 kA Icu at 380/415 V AC per IEC 60947-2, matching the H breaking capacity code.

What trip unit does the C25H42D250 use?

It uses a MicroLogic 2.2 electronic trip unit with L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous short-circuit) protection.

What compliance documentation does Schneider provide for C25H42D250?

The breaker is certified to EN/IEC 60947-2 and carries UL 60947-4-1 ratings. Pollution degree 3 per IEC 60664-1 and IK07 per IEC 62262 are documented.
