It's a 3-phase unit rated for 380-480 V input, delivering 4 kW (9.4 A) in normal use and 3 kW (7.2 A) under heavy-duty conditions. The IE2 efficiency rating means it meets the baseline for industrial motor drives in most applications.
The key number for most motor loads is the heavy-duty current: 7.2 A. That's the rating that governs continuous duty on a constant-torque application like a conveyor or a compressor. The normal-use 9.4 A covers variable-torque loads (pumps, fans) where the drive isn't hammered at full current all day. If your motor plate says 8 A FLA and it's a constant-torque machine, you'll want to step up to the next frame — this one's heavy-duty ceiling is 7.2 A. The 47.5-63 Hz input frequency range means it'll handle 50 Hz or 60 Hz supplies without a firmware change.
Physical & Mounting
Frame R1 is the smallest in the family — it's a compact module that bolts into a panel with standard DIN-rail or screw-mount options. The IP20 rating means no gaskets or sealed glands; you'll need a clean, dry cabinet. Open-type NEMA classification confirms it's not a standalone enclosure — plan for a backplate and some finger-safe shrouding if the install requires it.
