What the order code buys
The ABB ACS800-U1-0011-5+N685+P901 is a wall-mount AC drive from the ACS800-U1 series, carrying two field-installed option codes — +N685 and +P901 — that have to be read together with the base drive code, because the suffix pair changes what ships in the box and how it presents on the network. It is filed in the Motor Drives line under Motors & Motor Controls, which is the path a panel-builder or MRO buyer follows to confirm class before placing the BOM line.
Ratings on record
The single quantified figure on the spec sheet for this build is a chassis mass of 9.07 kg — the figure that decides whether the existing cabinet mounting plate and the lift path into the panel remain valid when this drive is being swapped in or out.
Same-frame sibling worth weighing
The ACS880-01-027A-5 weighs 10.41 kg and the ACS880-01-034A-5 weighs 10.43 kg, both versus 9.07 kg for this drive — verify the mounting plate rating before treating either as a direct swap.
