What it is on the bench
The ABB ACS380-040C-05A6-4+K469 sits in the ACS380 family of motor drives, with the +K469 suffix denoting the factory-fitted option bundle on this build rather than a different frame or current rating. At 1.43 kgs the unit is light enough for a single-technician lift onto a DIN rail or backplate, so handling does not dictate a two-person rig on the FAT floor.
Where the +K475 sits next to it
The sibling ACS380-040C-05A6-4+K475 carries the same base code with a different option suffix and a listed weight of 1.13 kgs versus the +K469 at 1.43 kgs; same frame and current class, but the option bundle has to be confirmed against the wiring diagram and option-card complement before a swap is cleared.
