What the code points to
The ABB ACS580-01-046A-4+J400 sits in the ACS580-01 family of general-purpose drives and is rated at IEC PN 22 kW, so on the BOM it lines up against a 22 kW induction or permanent-magnet motor on a 400 V class supply. Category placement is Motors & Motor Controls › Drives › Motor Drives, which is where a panel-builder expects to find it when sizing a variable-torque or constant-torque load in a control cabinet.
Ratings that actually decide fit
The 22 kW IEC PN figure on the order code is the headline selection number — it sets the motor shaft power ceiling this drive can command without immediate derating, and it is the number to match against the motor nameplate on the BOM line. The +J400 suffix is part of the ABB option-coding for the ACS580-01 frame; treat the full code as the orderable string rather than splitting the base and the option when quoting it into the BOM.
Handling and panel fit
The drive is listed at 5.35 kg, a one-person lift into a standard cabinet. Panel-cutout and clearance around the heatsink path need a quick check before mounting. Mount it with the cable-entry orientation matching the cabinet layout so the motor cable run stays as short as the layout allows; on this frame class a long motor pigtail is what usually bites first in the field, not the drive itself.
