The Siemens SENTRON 3VA1010-2ED32-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C — that's the full rating up to 50 °C, then it derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. For a panel that runs warm, the 100 A frame still holds up in a 50 °C ambient without derating, which is where many breakers start to lose headroom. The interrupting ratings are 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so at 415 V it handles a 32 kA fault, which covers most industrial distribution panels fed from a 1 MVA transformer.
Mounts in a standard distribution panel or motor control center; the 76.2 mm width (3-pole frame) and 70 mm depth fit the SENTRON 3VA family footprint. The shunt trip (STL) auxiliary release is built in, so you can remotely trip the breaker from an emergency-stop circuit or a PLC output without adding an external undervoltage coil. No auxiliary contact version means you'll need a separate 3VA9688-0BL32 auxiliary trip block if you want a status feedback signal back to the controller.
