The Schneider Electric C63R32M500 is a ComPacT NSX NSX630R circuit breaker with a MicroLogic 2.3 M electronic trip unit rated 500 A at 65 °C, designed for motor protection. Its breaking capacity hits 200 kA Icu at 415 V AC (50/60 Hz) per IEC 60947-2, so it clears high-fault currents on motor feeders without upstream coordination issues. The trip unit offers L (long-time overload), So (short-time short-circuit with fixed delay), and I (instantaneous) protection, plus selectable motor tripping classes 5, 10, or 20.
Mechanical durability is 15,000 cycles. Operating altitude derates above 2000 m; no earth-leakage protection built in (external RCD required).
