The Ics (service breaking capacity) at the same voltage is 65 kA, meaning it can handle repeated faults at that level and still carry rated current — a real-world selectivity and coordination number for the panel designer. The 4-pole (4P) configuration with neutral on the right handles three-phase plus neutral distribution. Fixed mounting on a base plate with rear vertical/horizontal connections — this is a switchboard or drawout-cradle install, not a DIN-rail snap. IP40 protection means it's for indoor, dry electrical rooms; no washdown duty. ## Selectivity and coordination The 66 kA Icu at 440 V and 50 kA Icu at 690 V give this breaker headroom for high-fault installations. The Icw (short-time withstand) is 65 kA for 1 s at 440 V and 36 kA for 3 s at 440/690 V — that sustained withstand allows downstream breakers to clear a fault before this one trips, enabling full selectivity in a distribution cascade. The 12 kV impulse withstand voltage (Uimp) confirms it handles switching surges in industrial environments.","metaTitle":"Schneider Electric ENW24256 EasyPact NW Circuit Breaker, 160","metaDescription":"Schneider Electric ENW24256 EasyPact NW circuit breaker, 1600 A rated at 40 °C, 66 kA Icu at 440 V AC, IEC 60947-2.
