The ABB ACS530-01-073A-4+N7562 (3ABD00049209-D) is a 37 kW variable-frequency drive in frame size R4, rated for 73 A normal-use output on a 380-480 V three-phase supply. It is wall-mounted with IP20 protection and carries IE2 efficiency classification.
The 73 A normal-use rating (Pn 37 kW) is the headline number for continuous motor duty. The light-overload current of 68 A (PlD 37 kW) applies when the drive runs below rated power but still needs to handle occasional overloads — useful for pumps and fans with variable load profiles. Both ratings are identical for power output at this frame, so the current difference is the deciding factor for cable sizing and thermal management.
Wall-mount enclosure, IP20, open-type NEMA. Accepts 47.5-63 Hz input. No derating curve published here, but the IP20 rating means it is intended for clean, indoor panel environments — not for washdown or dust-laden areas.
