The ABB 3ABD00045438-D is a general purpose wall-mounted drive rated for 90 kW normal use at 169 A output, with a heavy-duty rating of 75 kW at 145 A. It runs on 380-480 V three-phase input across 47.5 to 63 Hz, enclosed in an IP21 NEMA Type 1 housing at Frame Size R7.
For constant-torque or high-starting-torque applications — conveyors, crushers, extruders — the heavy-duty curve caps at 145 A (75 kW). The light-overload column at 161 A (90 kW) sits between the two, useful for applications with occasional peak demand. Match your motor's full-load amps to the appropriate duty column; oversizing to the normal-use figure on a heavy-duty application risks nuisance tripping.
Efficiency class
Rated IE2 efficiency. That is the standard efficiency level for this drive class. If your project mandates IE3 or IE4 for the motor-drive system, the drive itself does not carry the higher efficiency classification, but the motor selection will need to compensate.
