The Schneider Electric EVS16H3MW20 is a 3-pole drawout circuit breaker from the EasyPact EVS range, rated 1600 A at 40 °C with a breaking capacity of 65 kA Icu at 220...440 V AC and 50 kA Icu at 690 V AC per IEC 60947-2. The drawout mounting lets you rack the breaker out for maintenance or replacement without disturbing the bus connections, a standard requirement for main and tie breakers in industrial switchboards. The EVS Trip System2.0 electronic trip unit provides LI protection — overload (long-time) and instantaneous short-circuit. The 20-minute thermal memory means the trip curve remembers prior heating, preventing nuisance reclosure on a hot breaker after a fault.
Mechanical durability: 20,000 cycles with maintenance, 10,000 without. Electrical durability: 5,000 cycles at 440/690 V AC without maintenance per IEC 60947-2. Suitability for isolation is confirmed to IEC 60947-2, meaning the open contacts provide a visible air gap that meets safety isolation requirements — important for lockout/tagout procedures.
