The Siemens SENTRON 3VA1010-2ED32-0JC0 is a 3-pole molded case circuit breaker rated for 100 A continuous at 40 °C, with the TM210 thermal-magnetic release handling overload and short-circuit protection in a single device. That 100 A holds flat through 50 °C — only starts tapering at 55 °C (96 A), hitting 90 A at 70 °C, so in a warm panel you still have headroom. Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — enough for most industrial distribution boards on the secondary side of a 500 kVA transformer. It ships with a factory-fitted shunt trip (STL) release (order code 3VA9688-0BL32 for the integrated auxiliary trip assembly) and two HQ auxiliary switches, so you get remote tripping and status feedback without adding an external module.
The 3VA1010-2ED32-0JC0 measures 130 mm high, 76.2 mm wide (standard 3-pole MCCB footprint), and 70 mm deep — fits a 200 mm deep enclosure with room for rear-mounted busbars or a DIN-rail adapter. Spring-cage terminals on the line and load sides accept copper conductors up to the rated cross-section for 100 A; torque to the values stamped on the device nameplate.
