The C63R35E630 is a Schneider Electric ComPacT NSX630R molded case circuit breaker rated for 630 A at 40 °C, fitted with a MicroLogic 5.3 E electronic trip unit. The EN/IEC 60947-2 standard certifies it for industrial circuit-breaker duty, not just residential branch protection. The trip unit provides L (long-time overload), S (short-time short-circuit), and I (instantaneous short-circuit) protection curves, plus energy metering and time-stamped event logs. The electronic trip technology allows field-adjustable settings via the LCD display, so you can coordinate selectivity downstream without swapping the breaker.
Rated IP40 for the breaker body — suitable for general indoor panel installation where no washdown or dust ingress is expected. The IK07 impact rating means it withstands accidental tool drops during maintenance.
What the breaking capacity code tells you
At higher voltages the rating drops: 80 kA at 500 V, 65 kA at 525 V, and 45 kA at 690 V. If your system's available fault current at 690 V exceeds 45 kA, you need a higher-rated frame — the NSX630R won't hold there.
