The Schneider Electric ENW24104 is a 3-pole EasyPact NW circuit breaker rated 1600 A at 40 °C, built for distribution duty in AC networks at 50/60 Hz. Its 50 kA Icu at 220…440 V AC (42 kA at 690 V) tells you it can safely interrupt a fault up to that level without failing — that is the short-circuit capacity that governs selectivity coordination downstream. The Ics (service breaking capacity) matches the Icu at both voltage levels, meaning after clearing a fault at rated breaking capacity the breaker remains functional, not just safe; that is a full-selectivity design, not a sacrificial one. Drawout mounting means the breaker chassis stays wired to the bus while the moving portion pulls out for inspection or swap — no need to disconnect power cables. Rear connection with a 115 mm pitch without spreader matches standard switchgear busbar spacing.
Mounts on a rail in a drawout cradle — the fixed part bolts to the enclosure frame, the moving part slides in. Dimensions: 441 mm wide, 439 mm high, 395 mm deep. That depth matters for enclosure selection — a standard 600 mm deep cabinet leaves enough room for rear cables and the arc chute clearance. Rated insulation voltage 1000 V AC and impulse withstand 12 kV give headroom for 690 V systems. The 25 ms maximum breaking time and 70 ms closing response are coordination parameters — the breaker clears fast enough to let downstream devices ride through a fault without cascading.
