Duty ratings — which one fits your load
The 3ABD00047428-D: Normal-use output is 11 kW at 25 A; heavy-duty (higher overload margin) drops to 7.5 kW at 17 A. Light-overload sits at 11 kW / 23.8 A, close to normal but with a slightly lower current ceiling — useful if your fan or pump has a modest starting surge but runs near rated power. If you're driving a centrifugal load, normal-duty covers it. For a positive-displacement pump or a crusher start, spec the heavy-duty figure.
Frame size R2 — what it means in the panel
R2 is the frame for this 25 A class. It keeps the drive compact enough for a wall-mount layout but still leaves room for the integral EMC filter and braking chopper.
