The Siemens SENTRON 3VA2110-5JP32-0CC0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed up to that ceiling. Breaking capacity sits at 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. This is a line-protection design (not feeder or motor-protection profile), so it's suited for main or branch circuits where the priority is short-circuit and overload isolation rather than motor thermal overload curves.
The 86 mm depth matters when the panel door clearance is tight; check that the handle and any rotary-drive extension clear the enclosure cover.
