The Schneider Electric C63F4TM630 is a ComPacT NSX 4-pole moulded-case circuit breaker rated 600 A at 40 °C, with a TM-D thermal-magnetic trip unit providing L (overload) and I (short-circuit) protection per EN/IEC 60947-2. Its breaking capacity hits 36 kA Icu at 380/415 V AC — the F code on the nameplate — and derates predictably up to 690 V (10 kA Icu).
Deployment context — panel fit
IP40 enclosure protection, IK07 impact rating — fine for a clean indoor switchboard, not for washdown zones.
Listed as current production — no phase-out notice on record. This is a standard catalogue item in the ComPacT NSX family.
The TM-D trip unit is fixed thermal-magnetic, not electronic, so you get no adjustable long-time or short-time settings; it's a straight thermal curve for overload and a fixed magnetic pickup for short circuit. That makes it a simpler, more robust choice for a distribution board where you don't need selective coordination curves, but it limits flexibility if you're trying to achieve cascaded selectivity downstream.
