The Siemens 3VA2110-7JP32-0AA0 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. That flat thermal curve is the first thing to check when you're stuffing this into a warm panel or next to a hot transformer. That matters when you need coordination selectivity downstream or want to dial in the trip for a motor start or transformer inrush without nuisance opens.
Breaking capacity and voltage class
The interrupting ratings tell you where this breaker belongs in the fault-current hierarchy. At 240 V it's rated for 330 kA — that's a very high interrupting capacity, typical for a main or large feeder breaker in a low-voltage switchboard. At 500 V it drops to 187 kA, and at 690 V it's 3.7 kA — the sharp falloff above 500 V means this is a 500 V class device, not a 690 V general-purpose breaker.
That's a 3-pole MCCB footprint — standard for a 100 A frame in the SENTRON 3VA2 family. Panel cutout and mounting hole pattern match the 3VA2 base, so if you're swapping a failed 3VA2 of a different rating, the bus-bar connections and DIN-rail or screw-mount pattern should line up.
