The Schneider Electric EVS32H3NW20 is a 3-pole drawout circuit breaker from the EasyPact EVS range, rated 3200 A at 40 °C with an electronic EVS Trip System2.0 trip unit. It carries a 65 kA Icu breaking capacity at 220...440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2. The 1000 V AC rated insulation voltage (Ui) and pollution degree 4 per IEC 60664-1 suit it for main distribution in industrial switchgear where high fault currents and harsh environments are the norm.
Category B utilization means it's intended for distribution with selective coordination — the 20-minute thermal memory before and after tripping helps coordinate with downstream devices by retaining the thermal state during a reclose interval.
Deployment context
This breaker mounts on a rail base plate inside a switchgear cubicle — the drawout design means the fixed portion (cradle) stays wired to the bus, and the moving portion (the breaker itself) racks in and out. The 3-pole 3d protected poles with contact position indicator give visual confirmation of open/closed state, useful for LOTO procedures.
