The 140 mm width and 70 mm depth fit standard Siemens 3VA panel footprints; the IP40 front rating means it's fine inside a clean indoor enclosure but not for washdown areas. Breaking capacity is the headline spec here: 187 kA at 240 V AC, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V.
Thermal derating — what 250 A actually means at panel temperature
Above that, the curve is gentle: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C.
What's in the box — auxiliary contacts and releases
The auxiliary contact order code is 3VA9608-0BB11 if you need a spare or want to match it on a panel build. The N-conductor protection is set to 100% (full-rated), meaning the neutral pole carries the same current rating as the phases.
