Fixed mounting on a base plate, rear connections, and a 115 mm connection pitch without spreader. The 422 mm width, 352 mm height, and 297 mm depth define the panel cutout and clearance needed — factor in the 115 mm pitch when laying out bus bars. IP40 protection means it's indoor-rated, not for washdown; keep it in a clean, dry enclosure. The ENW24146 is listed as current production, so it's still a standard catalog item from Schneider. No obsolescence notice or last-time-buy on record. Mechanical durability: 20,000 cycles with maintenance, 10,000 without. Electrical durability: 5,000 cycles at 440 V without maintenance (Category B), 2,500 cycles at 690 V. That's typical for a high-current air breaker — not for frequent switching, but fine for infrequent load-break or fault-interrupt duty. Maximum breaking time is 25 ms, closing response 70 ms, so it coordinates with downstream protective devices on a time-current curve.","metaTitle":"Schneider Electric ENW24146 EasyPact NW Circuit Breaker, 250","metaDescription":"Schneider Electric ENW24146 EasyPact NW circuit breaker, 2500 A rated current, 66 kA breaking capacity at 440 V AC, IEC 60947-2.
