What the line card shows
The ABB ACS580-01-260A-4+J429 sits in the heavy end of the ACS580-01 wall-mount general-purpose drive family, fed from a 3-phase 380-480 V supply as catalogued. The 260 A frame is the current step where the drive leaves the cabinet-mount territory and starts to dictate floor-standing or reinforced wall-mount layout, which is the first thing a panel builder sourcing this code needs to confirm against the enclosure drawing.
What the ratings actually govern
The 3-phase 380-480 V input window listed for the ACS580-01-260A-4+J429 is the rating upstream coordination keys off: breaker frame, bus bracing, and cable sizing all derive from it. Match the upstream protective device and SCCR to that input, not to the motor nameplate alone.
