The ABB 3ABD00049875 is an ACH531-01 wall-mounted LV AC drive sized for HVAC fan and pump loads on 380-500 V three-phase supply. Normal-use output is 1.5 kW at 4 A; light-overload duty drops to 3.8 A at the same power rating, so the drive handles continuous centrifugal loads without derating.
The 4 A normal-use output current (In) at 1.5 kW is the continuous rating for a standard 3-phase induction motor on HVAC duty. Light-overload current (IlD) at 3.8 A covers variable-torque loads like fans and pumps without oversizing. Input frequency acceptance from 47.5 to 63 Hz covers 50 Hz and 60 Hz grids globally. IE2 efficiency meets the minimum for most commercial HVAC specs in regions where IE2 is still accepted for variable-speed operation.
Wall-mounted with an open-type NEMA enclosure (IP20). The R0 frame accepts standard cable glands for power and control wiring. Terminals accept 0.2–2.5 mm² for control signals; power terminals sized for the 4 A output. Mount close to the motor to keep output cable runs short and reduce reflected-wave stress on long leads.
