What it is
The ABB ACS850-04-014A-5+J400 sits in the manufacturer's cabinet-mount drive family, listed at 14-18 A on the output side of an industrial VFD chassis that weighs 4.54 kg. It is catalogued under Drives within the Motors & Motor Controls line, which puts the part in the same current-class bracket a buyer would specify when sizing a drive for a small-to-mid induction or permanent-magnet motor load.
Where it sits against the ACS880-01 family
The ABB ACS880-01-11A0-5 carries the same 4.54 kg chassis mass as the ACS850-04-014A-5+J400 and is the closest current-rated successor in the ACS880-01 frame, making it the natural cross-reference when an engineering change is opened to migrate the drive.
