The thermal derating curve is published: full 63 A up to 50 °C ambient, then 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
The 3VA1163-6EF36-0AH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep.
Why the 220 kA matters
That puts this breaker in the same league as larger-frame MCCBs for fault-current handling. It means you can place it downstream of a transformer or a high-capacity service entrance and still maintain selective coordination without stepping up to a physically bigger breaker. The TM240 release is fixed thermal and magnetic — no electronic adjustment, no communication, no ground-fault monitoring. It's a straightforward line-protection device: trip curve is what it is, no programming required.
