It carries a 66 kA Icu breaking capacity at 220...440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2 — meaning it clears bolted faults up to those levels without welding or rupturing, which is the deciding number for fault-current coordination with downstream gear. Four poles (4P), neutral on the right, rear-connected horizontal or vertical. Drawout mounting on rails means the breaker slides out for inspection or replacement without disturbing the busbars — standard for switchgear where uptime matters. IP40 enclosure keeps dust out of the arc chamber. The Ics (service breaking capacity) matches at 65 kA, so you get full rated performance without derating for repeated faults. Short-time withstand (Icw) is 65 kA for 1 s at 440 V, which lets it ride through downstream faults while a selective relay clears them — critical for maintaining power to healthy feeders in a distribution panel. Rated insulation voltage (Ui) is 1000 V AC, impulse withstand (Uimp) 12 kV — the breaker holds off transient surges common in industrial networks. ## Integration — Panel Fit and Connection Details Electrical durability at 440 V is 5,000 cycles without maintenance (Category B). Maximum breaking time is 25 ms, closing response 70 ms — fast enough for most selective coordination schemes.","metaTitle":"ENW24250 EasyPact NW Circuit Breaker, 2500 A, 66 kA Icu","metaDescription":"ENW24250 EasyPact NW drawout circuit breaker, 2500 A at 40 °C, 66 kA Icu at 440 V.
