The 50 kA Icu and Ics at 690 V AC tell you the same breaker can be used on 690 V systems but with a lower interrupting capability — a common derating on higher-voltage networks. Rated insulation voltage (Ui) is 1000 V AC, and impulse withstand (Uimp) is 12 kV. Pollution degree 4 per IEC 60664-1 covers harsh environments with conductive dust or heavy condensation. It is a standard catalog item from Schneider, not a last-time-buy scavenger hunt. Fixed-mount on a base plate with rear connections — this is a draw-out or plug-in alternative, so the breaker stays bolted in place. The 422 mm width, 352 mm height, and 297 mm depth are the envelope for panel layout; the 115 mm connection pitch matters when you're terminating busbars or cable lugs without a spreader. ## Durability and coordination Electrical durability at 440 V is 6,000 cycles without maintenance — that's the number to watch if the breaker sees frequent switching (e.g., capacitor bank or motor feeder duty). The short-time withstand (Icw) is 65 kA for 1 s at 440 V and 36 kA for 3 s at 440/690 V, which supports selective coordination with downstream breakers: you need that 3 s rating to let a downstream device clear a fault before this one trips. Maximum breaking time is 25 ms, closing response 70 ms — both typical for air breakers in this class.","metaTitle":"Schneider Electric ENW24144 EasyPact NW Circuit Breaker, 160","metaDescription":"Schneider Electric ENW24144 EasyPact NW air circuit breaker, 1600 A rated current, 66 kA Icu at 440 V, IEC 60947-2.
