At 690 V AC the Icu drops to 42 kA, which still covers most 690 V motor-control centers. The Ics (service breaking capacity) matches the Icu at both voltage levels, so you can reclose after a fault at full rating without derating the breaker — that's Category B utilization, meaning it's designed for sustained service in high-fault environments, not just backup protection. The 1600 A continuous rating is at 40 °C ambient. If your switchroom runs hotter — say 50 °C — you'll need to derate per the manufacturer's curve, which is standard for any air breaker this size. Fixed mounting on a base plate — no draw-out cradle. That saves panel depth but means the breaker must be isolated upstream before any maintenance. Rear connection, vertical or horizontal orientation, with a connection pitch of 115 mm without spreader. The neutral is on the right (4-pole configuration). Dimensions: 537 mm wide, 352 mm high, 297 mm deep. IP40 enclosure protection — fine for indoor switchgear, but not for washdown areas. The push-button control on the front cover gives local open/close/reset without opening the door. Mechanical durability: 20,000 cycles with maintenance, 10,000 without. Electrical durability: 6,000 cycles at 440 V AC without maintenance, 4,000 at 690 V. That's typical for a Category B air breaker — it's meant for switching under load, not just as a disconnect. The maximum breaking time is 25 ms, closing response 70 ms, so it clears faults fast enough for most coordination studies. The short-time withstand current (Icw) is 50 kA for 1 second at 440 V, 42 kA at 690 V, and 25 kA for 3 seconds at both voltages — that's the rating that matters for selective coordination with downstream breakers, because it tells you how long the breaker can carry a fault current without tripping while the downstream device clears.","metaTitle":"Schneider Electric ENW24240 EasyPact NW Circuit Breaker, 160","metaDescription":"Schneider Electric ENW24240 EasyPact NW air circuit breaker, 1600 A rated current, 50 kA Icu at 440 V AC, 4 poles, IEC 60947-2.
