That 4000 A continuous rating means it handles the main incoming feed for a large industrial switchboard or a high-current bus riser — not a feeder breaker for a motor control center. The drawout cradle lets you rack the breaker out for maintenance without unbolting power cables, which cuts downtime when you're swapping a trip unit or doing a megger test on the bus. Rated 65 kA Icu at 220…440 V AC and 50 kA Icu at 690 V AC per IEC 60947-2. The 25 ms maximum breaking time means the arc is quenched inside two cycles at 50 Hz, which limits the let-through energy on downstream gear. ## Trip unit and protection logic Fitted with the EVS Trip System5A electronic trip unit, rated 4000 A. It provides overload (long-time), short-time, and instantaneous short-circuit protection — that's the full curve set you need for selective coordination on a distribution main. The 20-minute thermal memory before and after tripping means the breaker remembers prior heating events, so it doesn't reclose into a still-hot conductor and nuisance-trip again. That matters on a line where a momentary overload from a large motor start could otherwise cause a lockout. Certified to IEC 60947-2, suitability for isolation marked on the device. Electrical durability: 5000 cycles at 440/690 V without maintenance per Category B. Mechanical durability: 20,000 cycles with maintenance, 10,000 without. That's a solid service life for a main breaker that cycles maybe a few dozen times a year.","metaTitle":"Schneider Electric EVS40H4NW5A EasyPact EVS 4000A Circuit Br","metaDescription":"Schneider Electric EVS40H4NW5A EasyPact EVS 4000A drawout circuit breaker. 65 kA Icu at 440 V AC, IEC 60947-2.
