What the code points to
The ACS880-01-124A-5: At 45.36 kgs, the unit is a genuine two-person lift and a meaningful load on any swing-out or wall-mount bracket — spec it as such on the installation drawing rather than treating it as a drop-in like a smaller frame.
Frame-size deltas inside the same family
Looking the other way down the family, the -065A-5 sits at 23.13 kgs and the -040A-5 at 18.14 kgs — roughly half the mass of the -124A-5 — which gives a sense of how sharply the ACS880-01 wall-mount format scales frame-by-frame as the current rating climbs.
Sourcing posture
ABB is the brand of record for the ACS880-01-124A-5.
