For repeated fault interruption (the service breaking capacity, Ics), the same 50 kA applies at 440 V and 42 kA at 690 V. That's Category B utilization, meaning it's rated for selectivity in distribution — it will clear a downstream fault without taking upstream feeders off-line. ## Deployment context — where this breaker goes This is a fixed-mount, rear-connected air circuit breaker for distribution switchboards. The 537 mm width, 352 mm height, and 297 mm depth — plus the 115 mm connection pitch without spreader — are the dimensions you need to verify against your bus-bar layout and cabinet cutout. Pollution degree 4 per IEC 60664-1 means it's rated for harsh environments with conductive dust or heavy condensation — typical in heavy industry, cement plants, or outdoor substations inside a shelter. The neutral position is left, with protection configurable as 3D (no neutral protection), 3D + N/2 (half-rated neutral), or 4D (full neutral protection).","metaTitle":"Schneider Electric ENW24127 EasyPact NW Circuit Breaker, 125","metaDescription":"Schneider Electric ENW24127 EasyPact NW air circuit breaker, 1250 A rated at 40 °C, 50 kA Icu at 440 V AC.
