It is a 4-pole (4P) fixed-mount unit with rear vertical/horizontal connections and a 115 mm connection pitch without spreader. The IP40 enclosure suits indoor distribution panels where dust ingress is limited but not washdown. At 690 V AC the Icu drops to 50 kA, and the Ics (service breaking capacity) mirrors those values — 65 kA at 440 V, 50 kA at 690 V. The Icw (short-time withstand) is 65 kA for 1 s at 440 V, 36 kA for 3 s at 440/690 V. That 3 s rating matters for selective coordination downstream: the breaker holds closed through a fault long enough for a branch device to clear, avoiding a full panel blackout. Category B utilisation confirms it is designed for selectivity, not just cable protection. Fixed mounting on a base plate. Rear connection position, vertical or horizontal orientation. The 115 mm connection pitch without spreader matches standard busbar drilling patterns for 800 A class breakers. Neutral is on the right. Pollution degree 4 per IEC 60664-1 means it handles conductive dust and heavy condensation — typical for industrial switchrooms, not clean conditioned spaces. ## Electrical Durability and Duty Mechanical durability: 20,000 cycles with maintenance, 10,000 without. Electrical durability at 440 V AC: 6,000 cycles Category B without maintenance, 4,000 cycles at 690 V. Maximum breaking time 25 ms, maximum closing time 70 ms.","metaTitle":"Schneider Electric ENW24253 EasyPact NW Circuit Breaker, 800","metaDescription":"Schneider Electric ENW24253 EasyPact NW circuit breaker, 800 A rated current, 66 kA Icu at 440 V AC, 4-pole, IP40.
