The Siemens SENTRON 3VA1132-6EE32-0AA0 is a 3-pole molded case circuit breaker (MCCB) with a TM220 thermal-magnetic trip unit, rated 32 A at 40 °C. The breaking capacity hits 220 kA at 240 V, 154 kA at 415 V, and still holds 17 kA at 690 V, so it handles high-fault utility feeds without cascading upstream. The TM220 trip gives you thermal protection for overloads and magnetic for short-circuits — no electronics to fail, no auxiliary power needed.
Sizing and derating for real panel conditions
The 32 A rating holds flat from 40 °C up to 50 °C, then starts a gentle slope: 31 A at 55 °C, 30 A at 65 °C, still 30 A at 70 °C. That's a practical advantage over breakers that derate harder above 40 °C. Power loss is 10.6 W maximum, which is modest for a 32 A MCCB. In a dense DIN-rail layout, that keeps the internal temperature rise manageable and reduces the derating you'd otherwise need on adjacent devices.
Panel fit and physical integration
The 3VA1132-6EE32-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 70 mm depth is worth noting if you're fitting it into a shallow enclosure or a gland-plate clearance issue — it's shallower than many MCCBs in this class, which helps with wiring space behind the panel door. Width of 76.2 mm is standard for a 3-pole frame; it occupies three 25 mm DIN positions if you're using a mounting plate.
