Drive selection memo — 18.5 kW normal-duty, R4 frame
The ABB 3ABD00059952 is an ACS380-04 series LV AC machinery drive module, rated 18.5 kW normal use at 38.0 A output current on a 380-480 V three-phase supply. Light-overload use (typically variable-torque, e.g. fans and centrifugal pumps) is 18.5 kW at 36.0 A, so the normal-use and light-overload curves converge at the same power rating. Frame size R4 means this drive occupies a specific mechanical footprint and bus-bar layout — if you're replacing an existing R4-frame drive from the same family, the mounting holes and power terminals align. The input frequency range is 47.5 to 63 Hz, covering 50 Hz and 60 Hz grids without derating. Active lifecycle status — this is a current-production model, not a phase-out or NRND part.
