The 690 V operational voltage (Ue) covers standard 400/480 V systems with headroom for 690 V industrial networks. The 1250 A frame is sized for large distribution loads — transformers, busway feeds, or high-density motor control centers. The 12 kV impulse withstand (Uimp) confirms it handles surge events typical of industrial mains.","metaTitle":"ENW24255 EasyPact NW Circuit Breaker, 1250 A, 66 kA","metaDescription":"ENW24255 EasyPact NW circuit breaker, 1250 A rated current, 66 kA breaking capacity at 440 V AC, IEC 60947-2.
