Breaking capacity steps down as system voltage rises: 440 kA at 240 V, 330 kA at 415/440 V, 220 kA at 500 V, and 52.5 kA at 690 V. For a 480 V panel, the relevant figure is the 415/440 V column at 330 kA, which covers virtually any North American industrial service.
The 3-pole footprint matches the standard SENTRON 3VA2 cutout; if you are swapping from a different MCCB family, check the mounting hole pattern against your existing bus bars.
