The rear connection and 115 mm connection pitch without spreader match standard switchgear bus riser spacing. If your fault study shows available current above 50 kA at the board, this is the variant you need. Pollution degree 4 per IEC 60664-1 means the breaker is rated for conductive environments — think pulp mill wet-end or cement plant dust — where creepage distances must handle condensation and contamination. The IP40 enclosure keeps out tools and wires but is not sealed; in a washdown zone you would mount it in a separate IP54 cubicle. ## Integration notes Electrical durability at 440 V is 5,000 cycles without maintenance, Category B. For a main incomer that operates a few times a year, that is effectively lifetime; for a welding or furnace breaker cycling daily, factor the reduced electrical life at higher currents.","metaTitle":"Schneider EasyPact NW ENW24138 2500A Circuit Breaker, 66kA","metaDescription":"Schneider Electric EasyPact NW ENW24138 circuit breaker. 2500 A rated current, 66 kA Icu at 440 V AC, IEC 60947-2.
