The 3ABD00058598-D: The ABB ACQ531-01-04A1-4+P972 is a 1.5 kW variable-frequency drive in Frame R1, sized for a 3-phase 380-480 V supply. Normal-use output current is 4 A; light-overload duty drops to 3.8 A at the same power rating. The IP20 open-type enclosure keeps it to panel-mount only — no standalone floor-mount.
The 4 A normal-use output (In) matches a 1.5 kW motor on a 400 V supply — that's the standard IEC sizing. Light-overload rating (IlD) at 3.8 A is nearly identical, so this drive doesn't carry a meaningful overload headroom; if your motor draws 4 A continuously, you're at the limit. Frame R1 is the smallest mechanical size in the ACQ531 family — expect compact DIN-rail or backplate mounting, but verify gland-plate clearance for your cable entry.
