Integrator note — ComPacT NSX630F, 570 A, 4P
The C63F44V570 is a Schneider Electric ComPacT NSX630F moulded-case circuit breaker with a 570 A electronic trip unit (MicroLogic 4.3) at 40 °C, four poles, and an F breaking-capacity code — 36 kA Icu at 415 V AC per IEC 60947-2.
Breaking capacity — what the F code means
The F breaking-capacity code gives 36 kA Icu at 380/415 V AC and 40 kA at 220/240 V AC. At 440 V it drops to 30 kA; at 525 V to 20 kA; at 690 V to 10 kA. That's the full interrupting rating per IEC 60947-2 — the breaker can clear a fault at those levels and still be reclosed. For UL 60947-4-1 applications (motor-circuit protectors), the same breaker carries 85 kA Icu at 240 V AC, 35 kA at 480 V, and 20 kA at 600 V. If your panel is UL-listed, use those numbers for the SCCR calculation.
Backplate-mounted, flat on the back, horizontal or vertical orientation. The 4-pole unit is 185 mm wide, 255 mm high, 110 mm deep — fits a standard distribution panel footprint. Front connections top and bottom; neutral on the left. Overvoltage category IV — suitable for main incoming supply. Ambient humidity 0–95 % non-condensing; altitude up to 2000 m without derating, 2000–5000 m with derating.
