It carries a breaking capacity of 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 500 V, with a steep drop to 3.7 kA at 690 V — so the available fault current at the panelboard determines which voltage tap you coordinate against.
That is unusual for an MCCB; most thermal-magnetic or electronic trip units start pulling current back above 40 °C. The adjustable thermal range spans 95 A to 756 A — wait, those numbers look like they belong to a different frame size. The 63 A frame's actual adjustable range is typically narrower; the evidence lists a minimum of 95 A and maximum of 756 A, which suggests this entry may be misaligned. The safe takeaway: the breaker is rated 63 A continuous, and the trip unit settings (if electronic) would be set below that. For coordination studies, use the 63 A as the nominal rating. The 3-pole construction handles three-phase loads.
Physical fit and auxiliary options
That is a standard SENTRON 3VA2 frame footprint — it occupies the same panel cutout and bus-bar spacing as the rest of the 3VA2 family. If you are replacing an existing 3VA2 breaker, this drops in without rewiring the bus. If you need shunt trip or alarm contacts, you add them externally.
