The ABB 3AXD50000814251 is an ACS180-04S-25A0-2 LV AC machinery drive module rated 5.5 kW normal-use output at 25 A, with a heavy-duty rating of 4 kW at 17.5 A. It runs on 200–240 V three-phase input and carries an IE2 efficiency level. The R3 frame keeps the panel footprint compact, and the IP20 open-type enclosure suits cabinet mounting.
The normal-use rating (Pn 5.5 kW, In 25 A) covers constant-torque applications like fans and pumps where the drive runs at or near full load continuously. The heavy-duty rating (PhD 4 kW, IhD 17.5 A) applies to variable-torque or intermittent loads — conveyors, crushers, or hoists — where the drive must deliver higher peak current without tripping. Matching the duty class to your motor's actual load profile avoids oversizing or nuisance trips.
