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. Rated insulation voltage is 800 V, so the breaker is rated for 690 V systems with margin. 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. No communication function, no ground-fault monitoring built in, and no undervoltage release on this variant; the auxiliary release is a shunt trip (STL) only.
Mounts on a standard DIN rail or can be screw-mounted in a panel. The 70 mm depth fits most 200 mm deep enclosures with room for wiring gutters. 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.
