The Schneider Electric EVS16H3MW5A is a 3-pole EasyPact EVS drawout circuit breaker rated 1600 A at 40 °C, built for distribution duty under IEC 60947-2. The 65 kA Icu at 440 V AC (50 kA at 690 V) gives you headroom on fault-clearing — that H breaking-capacity code means it handles high-fault panels without cascading upstream. The EVS Trip System5A electronic trip unit covers overload (long time), short-time, and instantaneous short-circuit protection, with a 20-minute thermal memory before and after tripping so you don't nuisance-trip on a reclose.
Category B utilisation means it's designed for selectivity with downstream breakers — the short-time delay on the Trip System5A lets you coordinate so a feeder fault doesn't take out the main. Drawout mounting means the breaker slides out of its cradle for inspection or swap without disturbing the bus connections — common in switchgear where uptime matters. IP40 keeps fingers and tools out but isn't sealed against dust or water; this lives inside an enclosure, not on the plant floor. Pollution degree 4 per IEC 60664-1 means the internal clearances handle conductive dust or condensation — typical for industrial switchgear, not clean-room panels.
Deployment context
This breaker mounts on a rail or base plate in a switchgear lineup. Connections are rear vertical or horizontal with a 115 mm pitch without spreader — that pitch matters when you're laying out bus bars or cable lugs. The digital display shows fault type (overload, short-circuit, internal fault) so a field tech reads the cause without pulling logs.
