The Schneider Electric ENW24132 is a 4-pole EasyPact NW fixed-mount circuit breaker rated 4000 A at 40 °C, with a breaking capacity of 55 kA Icu at 220–440 V AC and 42 kA Icu at 690 V AC per IEC 60947-2. The 4000 A CT rating matches the main bus for high-current distribution panels — this is a main breaker, not a feeder or branch device.
The 4000 A rated current at 40 °C ambient is the continuous load it carries without tripping — size your upstream transformer and bus bars for at least this. The IP40 enclosure keeps out tools and wires over 1 mm but is not washdown-rated; install in a dry, lockable enclosure.
