What the line is buying
The ABB ACS800-01-0040-3 is an AC drive in the ACS800-01 wall-mount frame, catalogued under the Motor Drives line as a general-purpose industrial frequency converter for three-phase motor control. Part number ACS800-01-0040-3, manufacturer ASEA BROWN BOVERI, is the identifying string on file; quote that exact code on every BOM line and RFQ rather than the family prefix. At 15.42 kgs the unit sits in a one-person lift bracket; a panel-build spec must reserve a mounting surface that can carry that mass continuously, and the cabinet layout should place the drive close to the motor feeder to keep the output cable run short and the common-mode loop small.
Sourcing posture
Panel OEMs and MRO planners who hold the ACS800-01-0040-3 on a frozen BOM should treat each line as a quoted-to-order item rather than a catalog-shelf part, and budget for the sourcing cycle the ABB channel carries on this frame.
What the spec ledger does and does not settle
Mass on file is 15.42 kgs; current frame, kW rating, supply voltage, overload duty, control interface, and braking chopper are not present in this evidence bundle and must be lifted from the ABB data sheet before the BOM line is committed. In a hot-strip mill or any cabinet with adjacent megawatt drives, the 15.42 kg mass and the wall-mount form factor of the ACS800-01-0040-3 keep the drive physically separated from the radiant heat of the rolls, but the EMC and thermal margin in that environment is set by ratings not present in this ledger and must be checked against the cabinet thermal curve.
