It's built for distribution duty in industrial switchboards and main feeders where you need high current handling and serious fault interruption. The 66 kA Icu at 220...440 V AC (50/60 Hz) per IEC 60947-2 means it can safely clear a bolted fault up to that level without welding contacts or venting plasma into the enclosure — that's the kind of rating that decides whether the upstream transformer breaker holds or the whole substation trips. That's the number you size your bus bars and cable terminations to. At 690 V the Icu drops to 50 kA, still substantial for industrial distribution. Rated insulation voltage is 1000 V AC, operational voltage 690 V AC. Impulse withstand is 12 kV, which covers most installation categories in industrial environments. Electrical endurance at 440 V is 6,000 cycles Category B without maintenance. That's a lot of switching for a breaker this size — it's not just a passive disconnect; it can handle routine switching of the feeder if your process requires it. Dimensions are 422 mm wide, 352 mm high, 297 mm deep. That depth is the critical one for enclosure depth selection — make sure your cabinet door clears the breaker face and any auxiliary devices mounted on it.","metaTitle":"ENW24145 EasyPact NW Circuit Breaker, 2000 A, 66 kA Icu","metaDescription":"Schneider Electric ENW24145 EasyPact NW circuit breaker, 2000 A rated, 66 kA Icu at 440 V.
