What it is, and why a buyer has it open
The ABB ACS800-04M-0320-5+E208+H360+J400+K458+P901+P916+P920 is an industrial AC drive in the ACS800-04M multi-drive-module frame, configured with option codes +E208, +H360, +J400, +K458, +P901, +P916 and +P920 for use inside a motor-drive lineup. Its position on the class path is industrial motor drive, and the part identifier on the nameplate is the full suffix-loaded string above — not a family prefix. The unit weighs 206.38 kgs, which is the figure that drives the real handling decision on this part: it is not a panel-door device, it is a floor-standing or cabinet-section module that the rigger plans around, and the panel layout has to carry that mass. The suffix code is a BOM line in itself. +E208, +H360, +J400, +K458, +P901, +P916 and +P920 are not cosmetic — they are ordered against a specific drive configuration, so a replacement has to match the full string, not the base code ACS800-04M-0320-5.
Where this class of drive sits on a panel
Motor drives in this class are the controlled-rectifier / inverter stage between the supply and the motor — they take the AC line in, run the DC link, and synthesize the variable-frequency output for the driven load, which is why the order code carries so much suffix detail (line filter, control board, I/O and application macros all ride on those plus-codes).
Same-manufacturer frames for cross-shop
The ABB ACS880-01-156A-5 is the wall-mount / cabinet-mount single-drive frame in the successor family — listed at 55.00 kgs, an order of magnitude lighter than the ACS800-04M-0320-5 at 206.38 kgs, which signals a different mechanical footprint and cooling arrangement rather than a drop-in. It belongs to a different drive family, so it is a planning alternative, not a same-slot swap. The ACS880-01-065A-5 sits further down the same ACS880-01 frame at 23.13 kgs, again confirming that the -01 family is a lighter, smaller-footprint line than the -04M module the seed belongs to. A panel that was specified around an ACS880-01-156A-5 will not accept the 206.38 kgs ACS800-04M-0320-5 without rework of the mounting, the cooling envelope and the cabling layout.
Sourcing posture
Specifying this drive into a BOM or a line-spare position is an exercise in matching the full suffix string ACS800-04M-0320-5+E208+H360+J400+K458+P901+P916+P920 and confirming the 206.38 kgs mass fits the cabinet — the sourcing channel then runs to RFQ rather than off-the-shelf.
