It delivers 22 kW normal-use output at 45 A, with heavy-duty rating of 18.5 kW at 38 A, on a 380-480 V three-phase supply. Frame size R4, IP20 enclosure, IE2 efficiency — this is the current-production variant for standard industrial motor control.
The 45 A normal-use current (In) and 22 kW power (Pn) define the continuous motor capacity at 400 V. For heavier cyclic loads — conveyors, crushers — the heavy-duty curve drops to 38 A (IhD) and 18.5 kW (PhD). Light-overload use (PlD) matches the normal-use power at 22 kW but with a slightly lower 42.8 A (IlD), reflecting a different duty cycle. Input frequency range of 47.5 to 63 Hz covers both 50 Hz and 60 Hz mains without derating. Frame R4 is the mechanical footprint — panel cut-out and mounting hole pattern are fixed for this size. IP20 means the module is intended for enclosure mounting, not standalone outdoor use. IE2 efficiency is the baseline for this power class; no premium-efficiency premium here, but it meets current EU regulations.
