What it is and where it sits in the ABB drives line
The ABB ACS880-11-124A-5 is a NEMA 1 enclosed regenerative variable frequency drive from the ACS880-11 series, listed at 112.04 kgs and catalogued under Motors & Motor Controls / Drives / Motor Drives. The -11 suffix is the package identifier for a line-regenerative (active front-end) ACS880 in a NEMA 1 stand-alone enclosure, so the same frame current is delivered as a fully wired cabinet-ready drive with the regen hardware on the input side — that is what separates it from the -01 book-mount modules of the same family.
