The Siemens 3VA1010-3ED32-0HC0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous at ambient temperatures from 40 °C to 50 °C, with a slight derating curve above that — 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That 100 A line is the one to size your feeder against; the thermal curve means you don't lose headroom in a warm panel unless it's pushing 55 °C+. Breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The design is line protection — not motor protection — meaning thermal-magnetic or electronic trip curves optimized for feeder and branch-circuit fault clearing, not overload-only motor starting profiles.
Maximum power loss is 25 W at rated current.
The auxiliary switch configuration is 2 HQ auxiliary switches plus a shunt trip (STL) release. If you need those, the 3VA family has other order codes — this one is a clean line-protection breaker with shunt-trip capability.
