What this order code actually is
The ACS800-01-0004-3+E200 is a wall-mount drive in the legacy ACS800 industrial drive family, option-coded +E200 on the base part string. The frame is genuinely compact: the unit ships at 3.48 kgs, so one tech can lift it onto the backplate without a second pair of hands, and the panel cutout is sized for a single-person install rather than a rigging plan. The +E200 option code on the suffix is the part a buyer specifying from a BOM line is most often chasing — it sits on top of the base drive, so quoting the base string alone will land you a stripped configuration.
Where this class of drive sits in a panel
ACS800-01 frames are the wall-mount slice of ABB's industrial drive catalogue — the form factor you reach for when the motor is small enough that a cabinet-mount drive would waste panel space, but the application still needs an industrial-grade controller rather than a micro-drive. On a commissioning bench this is the drive you parameterise with the standard ACS800 firmware toolchain and then wire to a three-phase induction or permanent-magnet motor through a shielded output cable — output filtering and grounding discipline matter more here than on a larger frame because the low-power end has less margin for switching noise coupling back into the control loom.
What the listed peers don't tell you
The two ACS880 peers in evidence — ACS880-01-11A0-5 at 4.54 kgs and ACS880-01-07A6-5 at 6.35 kgs — are not drop-in alternates for this drive. The ACS880 is the successor family, but it carries a different control firmware, a different assistant-panel interface, and a different parameter set, so a direct panel swap requires a full parameter migration and almost certainly a rewire of the control terminals. Treat them as a second-source for the motor output only after a full engineering review, not as a field swap.
