That 220 kA figure drops to 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 / 690 V, so the voltage class of your system dictates the actual SCCR you get. The 70 mm depth, 76.2 mm width, and 130 mm height fit the standard SENTRON 3VA footprint — it bolts into the same bus-bar and mounting pattern as other 3VA frame sizes, making a swap or upgrade straightforward without re-drilling the panel.
Rated current holds at 32 A from 40 °C through 50 °C, then drops to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. That's a gentle derating curve — only 2 A lost over a 30 °C rise — so you can pack it into a warm enclosure without a big capacity penalty. The maximum power loss is 13.1 W, which is modest for a 32 A MCCB; still, if you're stacking multiple breakers in a sealed panel, sum the losses and check the internal temperature rise against the derating table.
