The drawout mounting allows the breaker to be racked out for maintenance or replacement without disturbing the bus connections, a standard requirement for switchgear lineups where uptime matters. ## Withstand and coordination The short-time withstand current (Icw) is 55 kA for 1 s at 220...440 V and 42 kA for 1 s at 690 V, with a 3 s rating of 30 kA at 440/690 V. This Icw value is the one you size selective coordination against — if the downstream breaker clears a fault within 1 s, this breaker must hold closed without damage. ## Integration notes Drawout mounting with rear connections — the breaker slides into a fixed cradle with horizontal or vertical connection orientation. The 115 mm connection pitch without spreader matches standard switchgear bus spacing. Rated insulation voltage 1000 V AC, operational voltage 690 V AC. Electrical durability is 5000 cycles at 440 V and 2500 cycles at 690 V without maintenance; mechanical durability 20000 cycles with maintenance, 10000 without.","metaTitle":"Schneider Electric ENW24108 EasyPact NW Circuit Breaker, 400","metaDescription":"Schneider Electric ENW24108 EasyPact NW air circuit breaker, 4000 A rated current, 55 kA Icu at 440 V.
