What this MCCB carries and where it lands
The Siemens 3VA1032-3ED32-0HH0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for a continuous current Iu of 32 A at 40 °C, with a TM210 thermal-magnetic overcurrent release. That 32 A holds flat from 40 °C up through 50 °C — you only start losing headroom above 55 °C, where it derates to 30.72 A, then 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If your panel ambient runs near 65 °C, you spec this for a 29 A load, not a full 32 A. Breaking capacity is where this breaker earns its keep in a distribution board: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. That 52.5 kA at 415 V puts it comfortably above most 25 kA or 36 kA panelboard requirements — useful when the upstream transformer is big and the fault current is high. Rated insulation voltage Ui is 800 V, so it's at home in 400 V and 690 V networks.
Panel fit and auxiliary wiring
Envelope is 76.2 mm wide, 130 mm tall, 70 mm deep — that 76.2 mm is three 25.4 mm DIN-module widths on the rail, so it eats three slots. The front face carries an IP40 rating, meaning tools and fingers are kept out, but it's not sealed against washdown. Mount it inside a panel, not on the machine exterior. Auxiliary contact block is already integrated as 2 auxiliary switches plus 1 trip alarm switch (HQ designation). That saves a separate side-mount module and the extra DIN space it would take. A shunt trip release (STL) is fitted — part number 3VA9688-0BL30 — so you can remote-trip this breaker via a control signal. No undervoltage release, no ground-fault monitoring, no communication module on this variant. If you need those, you're looking at a different suffix.
Lifecycle and sourcing posture
For a procurement file: the product designation is molded case circuit breaker, reference code per DIN EN 81346-2 is Q. The integrated shunt trip order code (3VA9688-0BL30) is a separate line item if you ever need a spare release module.
