The Schneider Electric EVS16H3NW5A is a 3-pole drawout circuit breaker from the EasyPact EVS range, rated 1600 A at 40 °C and built to IEC 60947-2. That 1600 A trip unit rating means it handles full-load current for large distribution feeders — think main switchboards or heavy industrial loads. The electronic EVS Trip System5A gives you overload (long-time), instantaneous short-circuit, and short-time short-circuit protection, plus a digital display for reading fault cause and load current right on the front.
The H breaking capacity code delivers 65 kA Icu at 220...440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2. For a 1600 A frame, that's a high-interrupt rating suited to low-voltage utility transformers in the 2–3 MVA range where available fault current runs high. Maximum breaking time is 25 ms, so it clears fast enough to coordinate with downstream molded-case breakers.
Drawout mounting means the breaker slides into a cradle on a rail or base plate — no hard wiring of the main power connections; the rear connection points engage with stationary disconnects. The 441 mm width, 439 mm height, and 395 mm depth give you the cutout and clearance dimensions for the switchgear lineup. Connection pitch is 115 mm without spreader. IP40 keeps tools and fingers out but isn't sealed against water ingress.
Category B utilization means the breaker is intended for distribution, not direct motor starting — it's the main or feeder breaker, not a combination starter. Electrical durability is 5000 cycles at 440/690 V without maintenance; mechanical durability is 20000 cycles with maintenance, 10000 without.
