The EVS25H3NW5A is a 3-pole drawout air circuit breaker from the EasyPact EVS range, rated 2500 A at 40 °C and carrying a 65 kA Icu breaking capacity at 440 V AC (50/60 Hz) per IEC 60947-2. The electronic trip unit (EVS Trip System5A) provides overload (long-time), short-time, and instantaneous short-circuit protection, with a thermal memory that holds the thermal model for 20 minutes before and after a trip — so a reclose-and-trip sequence on a hot conductor is accurately timed. Drawout mounting means the breaker chassis stays wired in the switchgear; the moving portion pulls out for inspection or swap without disturbing the bus connections. The IP40 enclosure keeps out tools and fingers but not fine dust — expect this in a clean indoor switchgear lineup, not a washdown area.
Integration notes
Dimensions: 441 mm wide × 439 mm high × 395 mm deep. Rear connection with a 115 mm pitch without spreader. Mounts on a rail base plate. The drawout cradle needs clearance for the racking mechanism — verify the switchgear cubicle depth against the 395 mm plus handle throw. Pollution degree 4 means it's rated for conductive pollution environments (heavy condensation, occasional conductive dust), typical of industrial switchrooms.
