This MCCB's interrupting rating drops as system voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V (–).
Rated current holds flat at 100 A from 40 °C up to 50 °C, then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C (–). The 70 mm depth, 76.2 mm width, and 130 mm height (–) fit standard SENTRON 3VA panel footprints; the 25 W max power loss means it sheds heat into the enclosure, so factor that into your thermal budget.

At 440 V it interrupts 32 kA; at 500 V it interrupts 11.9 kA. For a 480 V system, the 32 kA figure at 440 V is the closest published rating — use that for SCCR coordination.
Yes, the auxiliary release is a shunt trip (STL), allowing remote or safety-relay-initiated opening.
