The ABB 3AXD50001057503 is an ACS880-37-0730A-3 regenerative drive rated for 400 kW normal use at 730 A continuous output, with a heavy-duty rating of 250 kW at 546 A. It runs on 380-415 V three-phase supply and carries IP22 protection in a Type 1 enclosure. The R8i+R8i frame size indicates a dual-module construction for the regenerative front end and inverter section.
Ratings in context
The 730 A normal-use current supports a 400 kW motor load under typical industrial duty. A light-overload rating of 701 A / 355 kW sits between the two, useful for variable-torque loads like pumps and fans. The 1000 m altitude rating is standard for this class; operation above that requires derating.
Installation notes
The IP22 enclosure is suitable for clean indoor environments; it does not protect against water jets or dust ingress. Type 1 NEMA equivalent means no drips or falling dirt exposure. The R8i+R8i frame is large — plan for floor-mounting with adequate clearance for the cooling airflow and cable entry. Three-phase input at 380-415 V, 48-63 Hz is standard for European and many Asian grids.
