Above that, it derates: 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 — so if your panel runs hot, you lose about 10 % headroom by the time you hit 70 °C. The interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V.
For a line protection breaker that cycles infrequently (a few times a year for testing), that is ample; for a switching duty cycling daily, it is not the right part.

Yes — the mounting centres and bus-bar pitch are identical across the 3VA frame sizes, so it fits the same footprint without rewiring. Verify the bus-bar ampacity rating for the higher 63 A continuous current.
