Panel integration note — EVS20H3MW20
The Schneider Electric EVS20H3MW20 is a 3-pole drawout circuit breaker from the EasyPact EVS family, rated 2000 A at 40 °C with a 65 kA Icu breaking capacity at 220...440 V AC 50/60 Hz per IEC 60947-2. The drawout mounting and rear connection position mean the breaker slides onto a rail base plate — no need to disconnect main power cables during swap-out, which cuts downtime on a 2000 A feeder.
The 2000 A trip unit rating and 65 kA Icu at 440 V tell you this breaker handles main or heavy feeder duty in a 480 V class distribution panel. Category B utilization means it's designed for selectivity with downstream breakers — the 25 ms maximum breaking time lets upstream devices ride through a fault without tripping.
Integration checklist
Mounts on a rail base plate with a 115 mm connection pitch without spreader. The 395 mm depth, 441 mm width, and 439 mm height require a swing-clear door or adequate front access for drawout racking. IP40 protection means it's for indoor panel installation — no washdown exposure. The electronic EVS Trip System2.0 provides LI protection (overload long-time and instantaneous short-circuit) with a 20-minute thermal memory that accounts for prior heating when re-energizing after a trip.
