Breaking capacity is the headline number here: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. Power dissipation maxes out at 10.6 W.
Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a standard MCCB envelope that drops into most Siemens SENTRON distribution boards and third-party enclosures with a 4-pole cutout. If you need shunt trip or aux contacts, you're looking at a different suffix in the 3VA1 family.
Rated current holds at 32 A from 40 °C through 50 °C, then gently steps down: 31 A at 55 °C and 60 °C, 30 A at 65 °C and 70 °C. That's a shallow derating curve — you don't lose much headroom in a warm panel.
