What the order code actually pins down
The ABB ACS800-01-0020-3+E202+L501+L502+L508+N804+P901 is the ACS800-01 wall-mount / cabinet-build AC drive in the 0020-3 frame, ordered as a configured SKU with the +E202, +L501, +L502, +L508, +N804 and +P901 option codes baked into the part number string. At 13.61 kgs on this build, the drive is in the bracket where a single technician can shoulder it onto the backplate with a proper lift, but it is heavy enough that the cabinet layout, mounting hardware and lifting plan should reflect real mass rather than treating it like a small wall-mount module.
Where this class of drive sits in the application
On the Motor Drives line under Motors & Motor Controls, the ACS800-01 family is the wall-mount / cabinet-mount AC drive tier used for direct-on-line motor control in industrial panels — the kind of part you specify when you need an industrial drive in a standard enclosure footprint rather than a through-panel or module-format unit.
Generation note vs the ACS880-01 family
The closest same-function family in the ABB catalog today is the ACS880-01 (wall-mount successor generation), with frame siblings ACS880-01-027A-5, ACS880-01-034A-5 and ACS880-01-040A-5 listed as peer references at 10.41 kgs, 10.43 kgs and 18.14 kgs respectively.
