Siemens 3VA1220-6MH32-0AE0 — 200 A MCCB for motor and feeder protection
This is the starter protection version (product version field), so it's set up for motor branch circuit protection — the TM120M release is a thermal-magnetic type tuned for motor starting inrush without nuisance tripping. The 75 W operating power at AC-3 duty at 400 V confirms it's sized for motor loads in that power class.
The 220 kA at 240 V is the headline number, but the real-world rating for most industrial 400 V panels is 154 kA at 415 V. That's still very high — well above what a typical 100 kA SCCR panel needs. Compared to a smaller-frame SENTRON like the 3VA1010-2ED32-0JA0 (which tops out at lower current and breaking capacity), this 3VA1220 frame handles the 200 A continuous rating and the 220 kA interrupt rating — it's a physically larger unit at 105 mm wide, 158 mm tall, and 70 mm deep. The 3VA1010 won't drop into the same panel cutout without checking the mounting footprint.

The continuous current rating holds at 200 A up to 50 °C, then derates to 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, and 180 A at 70 °C.
