The ENW24259 is a fixed-mount, 4-pole circuit breaker from the EasyPact NW range, rated 3200 A at 40 °C. That current rating places it squarely in main-feed or large-distribution duty — think incoming supply for an industrial switchboard or a high-current bus tie. The 66 kA Icu at 220…440 V AC tells you it can safely interrupt a fault up to that level without rupturing; the 50 kA Icu at 690 V covers higher-voltage installations.
Mounting is fixed to a base plate, with rear connections at a 115 mm pitch without spreader. The footprint is 537 mm wide × 352 mm high × 297 mm deep — plan for a substantial enclosure cut-out and adequate rear-access clearance for cable terminations.
Electrical durability at 440 V is 5,000 cycles without maintenance (Category B, per IEC 60947-2). That's typical for a Category B breaker — designed for distribution, not frequent switching. Maximum breaking time is 25 ms, and the maximum closing response time is 70 ms. The breaker is suitable for isolation, with a visible contact position indicator.
