The Schneider Electric EVS08H3MF20 is a 3-pole EasyPact EVS molded case circuit breaker rated 800 A continuous at 40 °C, with a 65 kA Icu breaking capacity at 440 V AC and 50 kA at 690 V AC per IEC 60947-2. The electronic EVS Trip System2.0 provides LI protection (long-time and instantaneous), with a 20-minute thermal memory that remembers the heat profile before and after a trip, so nuisance reclosing on a still-hot conductor is avoided. Rated insulation voltage is 1000 V AC, and the breaker is certified for isolation per IEC 60947-2 — meaning you can use it as a visible-break disconnect with the contact position indicator confirming the open state.
Fixed-mount design with rear vertical or horizontal connection positions. Mounting support is a rail base plate; connection pitch is 115 mm without a spreader. Dimensions: 422 mm wide, 352 mm high, 297 mm deep — fits standard switchgear cubicle cutouts.
Mechanical durability: 20,000 cycles with maintenance, 10,000 without. Electrical durability for Category B (distribution duty) is 5,000 cycles at 440/690 V without maintenance per IEC 60947-2. Maximum breaking time is 25 ms; maximum closing response time is 70 ms. That 25 ms clearing speed is fast enough to coordinate with downstream breakers in a selective distribution scheme, provided the trip curve settings are properly staged.
