Mass is 7.71 kgs for the bare drive — relevant when a field tech is lifting it onto the cabinet backplate during a swap, not a selection criterion by itself. The rating that decides the BOM line is the current class encoded in the order code suffix, which is the figure a procurement buyer is really buying when they pin ACS880-01-021A-5 against the motor nameplate.
Same-frame neighbors worth knowing
ACS880-01-052A-5 weighs 9.07 kgs, ACS880-01-027A-5 weighs 10.41 kgs and ACS880-01-07A6-5 weighs 6.35 kgs — all within the ACS880-01 wall-mount family. The mass deltas are panel-handling notes, not selection drivers; what actually separates them is the current class each suffix encodes, which is the figure that has to match the motor nameplate before a cabinet cut-out is approved.
Integration note
As an ACS880-01 frame-1 unit, ACS880-01-021A-5 takes the standard ABB cabinet footprint, gland plate pattern and line filter landing of the family — control wiring on the spring-cage terminal block, power landings sized for the suffix's current class. Fieldbus, safety and I/O extension cards occupy the option slots defined for the ACS880-01 platform; the slot map is shared across the frame, so a panel wired for an ACS880-01-052A-5 retains its option-card population when the drive is re-specified to the 021A current class.
