The 3VA2110-6HL32-0AA0 is a SENTRON 3VA2 molded case circuit breaker rated for line protection, carrying 100 A continuously from 40 °C all the way up to 70 °C — no derating needed in a warm enclosure (–). That 100 A figure is the Iu, the uninterrupted current it can pass without tripping. Three poles, so it switches all phases on a three-phase feeder. Operating voltage rated up to 690 V AC.
Breaking capacity — what it handles at fault
The interrupting rating is where this breaker earns its keep: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V.
Power loss max 10 W — negligible for enclosure thermal budgeting.
