38 A continuous, 15 kW normal-duty ceiling
The ABB ACS355-03E-38A0-4 is a frequency converter rated 38 A output current in normal use, delivering 15 kW (20 hp) continuous. Light-overload duty pushes the power ceiling to 18.5 kW — the extra headroom handles intermittent peak loads on pumps, fans, or conveyors without oversizing the drive frame. The IP20 enclosure is wall-mountable for panel or cabinet installation; frame size R4 keeps the footprint compact for a 38 A drive.
Panel integration — IP20 wall-mount checklist
Wall-mount the R4 frame with clearance for top-entry cables and bottom-side cooling airflow. The DC bus voltage range (250-840 V) allows common DC-bus configurations when multiple drives share a supply.
