The ABB ACS800-104-0070-5+Q950 is a 500V, 70 kVA inverter from the ACS800 series, specified with the AGPS-01 option board. This is not a part you spec into a new BOM freeze unless you have a line-down spare requirement or a legacy drive cabinet that already holds the ACS800 frame — the lifecycle stage is eol_hot, meaning ABB has formally ended production and the remaining supply moves through independent channels.
The 70 kVA rating at 500 V indicates apparent-power capacity. Verify the option-board pinout against your existing control wiring before committing the swap.
