The EVS08H3MW5A is a 3-pole drawout circuit breaker from Schneider Electric's EasyPact EVS range, rated 800 A at 40 °C and built to IEC 60947-2. That 800 A continuous rating means it handles full-load current for distribution feeders or large motor control centers without derating at typical 40 °C ambient — no need to oversize for a warm panel. The 65 kA Icu at 220...440 V AC tells you it can safely interrupt a fault up to that level without blowing apart; at 690 V the interrupting capacity drops to 50 kA, still plenty for most industrial services. The electronic EVS Trip System5A unit gives you overload (long-time), instantaneous short-circuit, and short-time short-circuit protection — adjustable curves for selectivity with downstream breakers. Drawout mounting means you can rack the breaker in and out of the cradle without disturbing the line and load connections — a real time-saver when you're swapping a unit for maintenance or after a fault. The IP40 enclosure protection keeps dust and accidental tool contact out but isn't rated for washdown; mount it in a clean indoor panel, not on a wet floor.
Integration and mounting notes
The drawout cradle mounts to a rail or base plate; rear connections are standard for vertical or horizontal bus. At 441 mm wide by 439 mm high by 395 mm deep, it needs a cutout that fits those dimensions plus clearance for the racking mechanism and arc-chute exhaust. The 115 mm connection pitch without spreader matches standard bus-spacing patterns — no custom bus adapters needed for most switchgear. The 20-minute thermal memory before and after tripping means the trip unit remembers the heat history of the breaker, so a reclose after a near-trip won't let it ride closer to the curve than intended.
