What this module is
The ABB ACS800-104-0580-7 is a single drive module in the ACS800-104 family, sized in the R8i frame, and built for cabinet integration rather than wall-mounting — i.e. it sits inside an engineered panel alongside the line filter, braking chopper, and I/O cabling, not on the panel door. Two duty points describe the same module: heavy-duty at 364 A delivering 355 kW, and light-overload at 467 A delivering 450 kW; the no-overload continuous ceiling is 486 A with a short-term peak of 727 A.
Reading the ratings
The heavy-duty figure of 364 A / 355 kW is the rating a panel designer picks against when the load is a constant-torque process — conveyors, extruders, crushers, mixers — because it represents the current the drive delivers continuously under that overload regime. The light-overload 467 A / 450 kW figure is the duty class used when the driven machine is variable-torque or rarely overloaded, such as fans, centrifugal pumps, or blowers. The absolute envelope of 486 A continuous and 727 A peak defines what the upstream cabling, line filter, and braking resistor must survive during transients; the drive itself can deliver that current only briefly before its own thermal model begins to derate the output. Heat dissipation inside the cabinet reaches 7.5 kW at full load, so the panel HVAC or closed-loop water cooling on the R8i frame must be specced to evacuate that loss before the module starts to derate itself.
