The ABB 3ABD50000038996 is an ACH580-01-039A-4 LV AC wall-mounted drive sized for 18.5 kW normal-use output at 38 A, with a heavy-duty rating of 15 kW at 31.6 A. It runs on a 380-480 V three-phase supply, 47.5-63 Hz, and carries IP21 protection in a NEMA Type 1 enclosure. Frame size R3.
Normal-use (Pn/In) at 18.5 kW / 38 A covers the standard pump, fan, and compressor curve — the load profile the drive sees most of its life. Light-overload (PlD/IlD) at 18.5 kW / 36.1 A sits between the two; it matches normal-use power but at a lower current, reflecting a different thermal duty cycle.
This drive carries an Active product status. No last-time-buy or phase-out notice applies. The IE2 efficiency level meets the baseline for most HVAC applications in regions where IE2 is still accepted; verify local motor-efficiency regulations if the drive is paired with a new motor.
