Siemens SENTRON 3VA1010-2ED32-0AA0 — 100 A MCCB, Line Protection, TM210 Release
Its interrupting capacity reaches 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V — so at typical 400 V class distribution voltages, it handles fault currents up to 32 kA, which covers most secondary distribution panels. Thermal derating is minimal up to 50 °C — it holds full 100 A — then drops to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
Dimensions are 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that drops into most Siemens SENTRON distribution panels and switchboard chassis without modification. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C — fine for most indoor industrial environments, but the upper operating limit matches the derating curve's endpoint, so don't expect full 100 A above 70 °C.
For BOM freeze or PCN watch, the 3VA platform is Siemens' mainstream MCCB line, so replacements and upgrades tend to follow the same physical footprint and accessory ecosystem.
If you need those features, you'd look at the 3VA1 with the appropriate suffix.
