The Siemens SENTRON 3VA1032-3ED32-0KA0 is a 3-pole molded case circuit breaker (MCCB) rated for 32 A continuous, designed for line protection in industrial distribution panels. It carries a TM210 thermal-magnetic release — the '210' indicating a fixed thermal trip and magnetic adjustment range centered around 10x In — so it handles moderate inrush from motor starters or transformer banks without nuisance tripping on the magnetic element. Interrupting capacity is the headline here: 75.6 kA at 240 V AC, dropping to 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 75.6 kA figure at 240 V means it can safely clear a bolted fault on a 240 V secondary bus without the arc flashing upstream — critical for selective coordination in a multi-level distribution. At 690 V the 7.5 kA rating still covers most motor branch circuits, but you'll want to verify the available fault current at the point of installation. The 32 A rating holds from 40 °C through 50 °C ambient; it derates to 31 A at 55–60 °C and 30 A at 65–70 °C. That's a mild derating curve — the thermal element is well-ventilated inside the 70 mm deep × 76.2 mm wide × 130 mm high case.
Spring-cage terminals accept 0.2–2.5 mm² solid or ferruled stranded conductors — verify the lug kit if you're paralleling larger cable. Operating temperature range is -25 °C to 70 °C; storage from -40 °C to 80 °C. The 10.6 W maximum power loss at full load is modest — no forced cooling needed in a typical IP54 panel, but account for it in the thermal budget if the enclosure is tightly packed with other heat sources.
