What this drive module is
The ABB 3ABD00046201 is a low-voltage AC machinery drive module, order code ACS380-040C-050A-4+K454. It delivers 22 kW normal-use output power at 50 A, with heavy-duty and light-overload ratings at 45 A and 48 A respectively, all at the same 22 kW power level. Input accepts 380-480 V three-phase, 47.5-63 Hz. The drive is frame size R4, IP20, open-type NEMA enclosure, and carries IE2 efficiency classification.
The 22 kW normal-duty rating at 50 A is the continuous motor rating for a standard 4-pole induction motor on 400 V supply. Light-overload (48 A) sits between the two. All three power ratings are identical at 22 kW — the current difference reflects the drive's internal thermal model for different duty cycles. Frame R4 determines the physical mounting footprint and the bus-bar / cable lug sizes; verify panel cut-out and gland plate dimensions against the ACS380 installation manual before laying out the cabinet.
Integration notes
Open-type NEMA enclosure means no additional factory-installed conduit box; the installer provides the branch-circuit protection and disconnect per local code. IE2 efficiency is the base level for this class; if the driven motor is IE3 or IE4, the drive itself does not limit system efficiency.
