The 3ABD00046186: The normal-use 22 kW / 45 A curve fits a standard 22 kW induction motor running at full rated current. The heavy-duty 18.5 kW / 38 A rating is the one to use when the load profile includes sustained overloads or frequent starts — it gives you headroom without jumping to the next frame. Pick the rating that matches your actual motor nameplate and application class, not the highest number.
Efficiency class
Rated IE2 efficiency level, which meets the minimum for many industrial applications. If your project requires IE3 or IE4 for regulatory compliance or energy targets, check the motor-drive combination as a system — the drive itself is IE2, but the overall drive-motor efficiency depends on the motor class and operating point.
