Siemens 3VA2225-6HN32-0AH0 — 250 A SENTRON MCCB with ETU350
Breaking capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 6 kA at 690 V — the 240 V figure covers most North American 240/277 V distribution panels, while the 415/440 V ratings handle European 400 V industrial mains. Current rating holds at 250 A from 40 °C through 50 °C ambient, then derates linearly to 213 A at 70 °C — the full thermal curve is documented, so no guesswork for high-temp enclosures.
If you need those, the 3VA2 family carries plug-in accessory slots for later addition.
