The Schneider Electric ENW24130 is a fixed-mount, 4-pole EasyPact NW circuit breaker rated 2500 A at 40 °C with a breaking capacity of 50 kA Icu at 220...440 V AC and 42 kA Icu at 690 V AC, both per IEC 60947-2. The Ics (service breaking capacity) matches the Icu at those voltages, so after clearing a fault at rated Ics the breaker remains functional, not just safe; that matters for processes where a fault can't mean a line-down replacement. The 4P 4d protected poles with left-side neutral suit a 4-wire + ground system where the neutral is switched and protected.
Electrical durability at 440 V is 5,000 cycles without maintenance — that's the number to watch for a breaker that sees frequent switching (e.g., capacitor bank or large motor feeder). If your application cycles more than that per year, consider a contactor in series for the switching duty and let the breaker serve as backup protection only.
Fixed mounting on a base plate, rear connection with a pitch of 115 mm without spreader. The 537 mm width, 352 mm height, 297 mm depth define the footprint for panel layout — this is a substantial frame, not a DIN-rail device. Vertical or horizontal connection orientation gives flexibility for busbar routing.
