At 690 V the breaking capacity drops to 50 kA Icu, still substantial for industrial 690 V networks. The unit carries IEC 60947-2 certification, the standard for low-voltage switchgear and controlgear, and is suitability-for-isolation marked — meaning you can use it as a visible disconnect point without a separate switch. ## Trip unit and protection The EVS Trip System2.0 is an electronic trip unit with LI protection — overload long-time and instantaneous short-circuit. The 4000 A CT rating matches the breaker frame. Maximum breaking time is 25 ms, fast enough to limit let-through energy on a bolted fault. Fixed-mount design on a rail or base plate. Rear connection with a 115 mm pitch without spreader — plan the bus bar drill pattern accordingly. Pollution degree 4 per IEC 60664-1 — the highest rating, for harsh industrial atmospheres with conductive dust or condensation. Mechanical durability is 20,000 cycles with maintenance, 10,000 without; electrical durability is 5,000 cycles at rated voltage. That's a long-life breaker for a main feeder that sees few operations per year.","metaTitle":"Schneider Electric EVS40H3NF20 EasyPact EVS Circuit Breaker,","metaDescription":"Schneider Electric EVS40H3NF20 EasyPact EVS circuit breaker. 4000 A rated current, 65 kA Icu at 440 V AC.
