At 690 V the Icu drops to 50 kA, so if your system runs at 690 V, the available fault current must stay under that ceiling. ## Environmental and isolation capability Rated insulation voltage 1000 V AC and impulse withstand voltage 12 kV — the breaker holds off transients common in industrial networks. Mechanical durability is 20000 cycles with maintenance, 10000 without; electrical durability is 5000 cycles at 440 V, 2500 at 690 V.","metaTitle":"Schneider Electric ENW24252 EasyPact NW Circuit Breaker, 400","metaDescription":"Schneider Electric ENW24252 EasyPact NW circuit breaker, 4000 A rated current, 66 kA Icu at 440 V, IEC 60947-2.
