The Siemens 3VA2010-5HL32-0AB0 is a SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V.
That 86 mm depth is the can depth behind the panel — check your gland plate clearance if you're retrofitting into a shallow enclosure. No communication function means no Modbus or PROFIBUS gateway inside — if you need remote trip indication, the 2 auxiliary switches HP are your only signal path.
