The ABB ACS800-104-0125-5+G304+Q950 is an AC inverter drive on the ACS800 platform, catalogued as an ASEA BROWN BOVERI AC INVERTER DRIVE and filed on the Motors & Motor Controls / Drives / Motor Drives line. The suffix string carries two factory option codes (+G304, +Q950) appended to the base ACS800-104-0125-5 drive — those codes need to ride on the PO so the replacement lands as a like-for-like configuration rather than a base unit.
Handling and panel support
Listed weight is 38.00 kgs, which puts the unit on the lifting-class side of the Motor Drives line — a two-person lift or hoist, and the panel back-plate or cabinet floor needs to be rated for that mass at the mounting footprint.
Where this class sits in the panel
ACS800-104 inverter drives of this rating band are sized for industrial motor control in MCC and process skid cabinets, where the drive sits between the line entry and the motor and is parameterised to the connected machine rather than the line.
Cross-shop candidates
The ACS550-U1-059A-4+B055 is the older ACS550 platform at 36.29 kgs with code 4, not a voltage-equivalent swap.
