The Schneider Electric ENW24248 is a 4-pole drawout circuit breaker from the EasyPact NW range, rated 1600 A at 40 °C with a 66 kA Icu breaking capacity at 220...440 V AC 50/60 Hz per IEC 60947-2. The 65 kA Ics (service breaking capacity) at the same voltage tells you it can clear a fault and be immediately returned to service without inspection, which matters for uptime in continuous-process plants.
The 12 kV impulse withstand (Uimp) confirms it handles switching surges and lightning-induced transients on exposed feeders. Pollution degree 4 per IEC 60664-1 means the creepage distances are sized for conductive dust or condensation — think cement plants or unheated switchrooms, not just clean data centers.
Drawout mounting and panel integration
Drawout mounting means the breaker chassis stays wired to the bus, and the moving portion racks out for maintenance or swap without disturbing the primary connections. Rear vertical/horizontal connection positions give flexibility for cable entry direction in the switchgear lineup. The 115 mm connection pitch without spreader is the dimension to check against your existing bus bar centers — if you're retrofitting into an older board, measure first. IP40 protection is fine for indoor switchgear; no washdown rating here, so keep it out of the hose-down zone.
