The EVS08H3NW5A is a Schneider Electric EasyPact EVS drawout circuit breaker rated 800 A at 40 °C, with a 65 kA Icu breaking capacity at 440 V AC (50/60 Hz) per IEC 60947-2. The electronic EVS Trip System5A unit provides overload (long-time), instantaneous short-circuit, and short-time short-circuit protection, with a 20-minute thermal memory before and after tripping so it remembers prior heating events and doesn't reset too aggressively. It is a 3-pole (3P 3d) device with rear vertical or horizontal connection, drawout mounting on a rail or base plate, and a 115 mm connection pitch without spreader. The drawout design means the breaker can be racked out for safe maintenance without disconnecting power wiring — standard for switchgear where uptime and isolation matter. IP40 protection suits indoor panel environments; pollution degree 4 per IEC 60664-1 means it tolerates conductive dust or heavy condensation, so it's suited for industrial distribution boards in pulp/paper, cement, or similar dirty atmospheres.
Integration notes for panel builders
Physical footprint: 441 mm wide, 439 mm high, 395 mm deep. Drawout chassis requires rear access for the power connections (vertical or horizontal orientation). The 115 mm pole pitch without spreader matches standard bus-bar spacing in LV switchgear. Electrically operated via the control circuit, with a digital display on the trip unit for fault indication (overload, short-circuit, internal fault). Contact position indicator gives visual confirmation of open/closed state without opening the door. Rated for category B utilization — 5000 electrical cycles at 440/690 V without maintenance per IEC 60947-2, and 20000 mechanical cycles with maintenance. The 25 ms maximum breaking time means fast fault clearance, which limits let-through energy on downstream components.
