The Schneider Electric C063N32AFM is a fixed-mount, manually operated 3-pole molded case circuit breaker from the ComPacT NS new generation family, rated 630 A at 50 °C with a MicroLogic 2.0 A electronic trip unit. That 630 A figure is the trip-unit rating, not a frame maximum — the breaker is sized for distribution feeders or large motor branch circuits pulling that continuous current. The 85 kA Icu at 240 V AC and 50 kA Icu at 415 V AC (per IEC 60947-2) tell you the interrupting capacity at those voltages; for a 415 V distribution panel, 50 kA Icu means it can safely clear a fault up to that level without upstream devices needing to trip. The MicroLogic 2.0 A provides L (long-time overload) and I (instantaneous short-circuit) protection, with an ammeter display and 20-minute thermal memory for re-close coordination after a trip.
Mounts fixed to a backplate via the 70 mm connection pitch — no DIN-rail adapter, so plan for bolt-down installation inside a distribution cabinet. IP40 enclosure protection keeps dust out but isn't rated for washdown; install in a clean, dry indoor panel. The IK07 impact rating means it survives a 2 J hammer blow — fine for a locked electrical room, not for a production floor where tools get dropped on it regularly.
