The ABB 3ABD00057989-D is an ACS530-04 series drive rated for 250 kW normal-use output at 505 A, with a light-overload current of 485 A at the same power level. The unit is frame size R10, open type (IP00), and carries IE2 efficiency classification.
The 505 A normal-use current (In) is the continuous rating for a typical motor load; the 485 A light-overload figure (IlD) applies when the drive is sized for a slightly lower duty cycle. Both are at the same 250 kW output, so the overload headroom is minimal — if your application expects sustained overloads above 105% of In, consider a larger frame. The IP00 open-type enclosure means the drive is intended for installation inside a panel or cabinet that provides the environmental protection. Frame R10 is a physical size that determines mounting hole pattern and bus-bar spacing; verify cabinet cutout dimensions against the ABB mechanical drawing for this frame.
