The Schneider Electric ENW24133 is an EasyPact NW drawout circuit breaker rated 800 A at 40 °C, with a 66 kA Icu breaking capacity at 220...440 V AC (50/60 Hz) per IEC 60947-2. Three-pole, 3d protected, with a drawout mechanism for racking in and out of the cradle without disturbing the power connections. IP40 enclosure keeps out tools and fingers but not water — install in a dry indoor switchgear lineup.
The H breaking capacity code (66 kA Icu at 440 V) puts this in the high-interrupting tier for its frame size. Service breaking capacity Ics is 65 kA at the same voltage — meaning after clearing a 65 kA fault the breaker is still rated to carry and switch load current, not just a one-shot device. Short-time withstand Icw is 65 kA for 1 s at 440 V, which supports downstream selectivity with other breakers in the same lineup. Rated insulation voltage Ui is 1000 V AC, impulse withstand Uimp is 12 kV — the breaker handles the transient surges common in industrial distribution without flashover.
Dimensions: 441 mm wide, 439 mm high, 395 mm deep. That depth includes the drawout mechanism and arc chutes — measure the enclosure depth to confirm the breaker racks in fully without door interference.
