Drive specs and fit
The ABB ACQ531-01-04A1-4+P974 (3ABD00058644-D) is a 1.5 kW, 4 A normal-use drive in Frame R1, running on 380-480 V three-phase input at 47.5-63 Hz. That 4 A rating is the continuous output current for normal-duty motor loads — sized for a standard 1.5 kW induction motor on a pump or fan. Light-overload use (3.8 A) covers the same power but with a slightly lower current headroom for constant-torque applications. Wall-mounted, IP20 enclosure — suited for clean, dry indoor panels. Open Type NEMA means it needs an enclosure for dust or washdown environments. IE2 efficiency level meets the base line for standard induction motors; no premium-efficiency premium built in.
