The ABB 3ABD00046581-D is an ACS580-01 general-purpose wall-mounted drive rated for 18.5 kW normal use at 38 A output, with a heavy-duty rating of 15 kW at 31.6 A. It accepts 380-480 V three-phase input across 47.5-63 Hz and carries IE2 efficiency. The IP21 enclosure and NEMA Type 1 rating suit clean indoor panel environments.
The normal-use current of 38 A (18.5 kW) is the headline number for sizing a standard motor load. The heavy-duty curve drops to 31.6 A (15 kW) — that is the rating to use for constant-torque applications like conveyors or extruders where the drive must sustain full torque at low speed without derating. The light-overload rating of 36.1 A (18.5 kW) sits between the two, useful for pumps and fans with moderate overload cycles.
