The 65 kA Icu at 220–440 V AC is the breaking capacity that governs fault clearance — it safely interrupts a 65 kA prospective short-circuit current without welding or rupturing, which is the figure your coordination study needs for upstream transformer or busbar protection. The EVS Trip System2.0 electronic trip unit provides LI protection — overload (long-time) and instantaneous short-circuit — with a 20-minute thermal memory that remembers prior heating so nuisance trips don't cascade on reclose. That memory window matters for motor feeders where a hot restart could otherwise cause a false trip. Pollution degree 4 per IEC 60664-1 means the breaker is rated for harsh environments — conductive dust or condensation won't cause tracking across the insulation. That's unusual for a distribution breaker and tells you it's built for industrial switchgear, not clean conditioned spaces. ## Panel and integration fit Drawout mounting means the breaker slides into a cradle — no hardwiring the main contacts for removal. That's the standard for switchgear where you need to rack out for maintenance or replacement without de-energizing the bus. The rear connection accepts vertical or horizontal bus orientation, and the 115 mm connection pitch without spreader matches common switchgear bus spacing. The rail base plate is the mounting support; it bolts into the enclosure floor. At 441 mm wide, 439 mm high, and 395 mm deep, the breaker fits standard low-voltage switchgear compartments. Electrical durability is 5000 cycles at rated voltage without maintenance; mechanical durability is 20000 cycles with maintenance, 10000 without. That's typical for a distribution breaker in Category B — it's designed for infrequent switching, not motor-starting duty. The 25 ms maximum breaking time and 70 ms maximum closing time give you the clearing speed for coordination.","metaTitle":"Schneider Electric EVS08H3MW20 EasyPact EVS 800A Circuit Bre","metaDescription":"Schneider Electric EVS08H3MW20 EasyPact EVS circuit breaker, 800 A rated, 65 kA Icu at 440 V AC, 3-pole drawout, IEC 60947-2.
