The drawout cradle lets you rack the breaker out for maintenance or replacement without disturbing the rear-connected power conductors, which is the standard arrangement for switchgear lineups in industrial distribution. ## Trip unit and protection — LI curve, thermal memory, 25 ms clearing The EVS Trip System2.0 is an electronic LI (long-time + instantaneous) unit. Long-time overload protection follows an I²t curve you can adjust for the load profile; instantaneous short-circuit protection clears in a maximum 25 ms. That 25 ms is the total break time — arcing plus mechanical opening — which is fast enough to limit let-through energy for downstream components. That matters for motor circuits or repeated inrush loads where nuisance tripping on a second start is a real risk. ## Mounting and integration — drawout cradle, rear connection, IP40 Mounts in a drawout cradle on a rail base plate; connection pitch is 115 mm without a spreader. Rear connection (vertical or horizontal orientation) mates to the switchgear bus. Pollution degree 4 per IEC 60664-1 means the insulation system is rated for continuous conductive contamination (dust, condensation), which is the typical environment in cement plants, steel mills, and heavy industrial substations. ## Durability and duty — Category B, 5000 electrical cycles without maintenance Electrical durability is 5000 cycles at rated voltage without maintenance; mechanical durability is 20000 cycles with maintenance, 10000 without.","metaTitle":"Schneider EasyPact EVS40H3MW20 Circuit Breaker, 4000 A, 65 k","metaDescription":"Schneider Electric EasyPact EVS40H3MW20 3-pole drawout circuit breaker, 4000 A rated current, 65 kA Icu at 440 V AC, IEC 60947-2.
