The Siemens SENTRON 3VA2063-5JQ32-0CC0 is a 3-pole molded case circuit breaker rated for 63 A continuous current (Iu) across a 40 °C to 50 °C ambient, derating to 53.55 A at 70 °C — so in a warm enclosure you still get full 63 A up to 50 °C, then a predictable 5% per step above that.
Maximum power loss is 7.9 W, so heat buildup in a sealed cabinet is manageable — no forced ventilation required for a single unit, but cluster several together and you'll want to check the cumulative dissipation.
Yes, the ETU560 trip unit has built-in communication function for integration with SENTRON bus systems.
