The Schneider Electric EVS25H3NF20 is a 3-pole EasyPact EVS circuit breaker rated for 2500 A at 40 °C, with a 65 kA Icu breaking capacity at 220…440 V AC and 50 kA at 690 V AC per IEC 60947-2. It uses an electronic EVS Trip System2.0 trip unit providing overload (long-time) and instantaneous short-circuit protection.
The electronic trip unit allows adjustment of the long-time pickup and delay, plus an instantaneous setting — the 20-minute thermal memory before and after tripping prevents nuisance reclosure on a hot conductor. Category B utilisation means the breaker is intended for distribution with no specific short-time delay requirement, and it carries 5000 electrical cycles without maintenance at 440/690 V. Pollution degree 4 per IEC 60664-1 means the breaker is rated for continuous conductive contamination (e.g., dust with moisture), so it can be placed in industrial panels without sealed enclosures. Suitability for isolation per IEC 60947-2 means the open contacts provide a visible disconnect gap — no separate isolator needed downstream.
Integration notes
Electrically operated — the closing coil draws from the control circuit. Maximum closing response time is 70 ms; maximum breaking time is 25 ms. The contact position indicator is visible on the front of the breaker for local status checks.
