Rated insulation voltage is 1000 V AC and operational voltage 690 V AC, so it handles standard 400/480 V systems with margin. Fixed mounting on a base plate, rear connection, with a connection pitch of 115 mm without spreader. The 4-pole configuration has the neutral on the right. Dimensions are 537 mm wide by 352 mm high by 297 mm deep — account for that depth when laying out the enclosure depth and gland-plate clearance. IP40 protection means it is splash-proof from solid objects larger than 1 mm but not sealed against water ingress; install in a dry indoor switchboard or add a weatherproof enclosure for outdoor use. Designed and tested to IEC 60947-2 for air circuit breakers. Suitability for isolation is confirmed per that standard, meaning you can use it as a visible-break disconnect. Electrical durability is 6000 cycles at 440 V without maintenance (Category B), and mechanical durability is 20000 cycles with maintenance. Maximum breaking time is 25 ms, closing response time 70 ms.","metaTitle":"Schneider Electric ENW24257 EasyPact NW Circuit Breaker, 200","metaDescription":"Schneider Electric ENW24257 EasyPact NW air circuit breaker, 2000 A rated current, 66 kA breaking capacity at 440 V, IEC 60947-2.
