What this order code actually is
The ABB ACS380-040C-17A5-2+K475 sits in the ACS380 machinery-drive family at the 17A5 current frame on a single-phase input, with the +K475 option suffix applied at order entry. The suffix is not decorative; it changes the option set on the build. The input class tells you where this drive physically fits: single-phase supplies, typically fed from a 230V light-industrial feeder or a step-down from a 400V three-phase panel. That input class drives the breaker and cable sizing upstream.
Frame and option suffix — the two things the BOM line actually depends on
The 17A5 in the order code is the frame, and +K475 is the option. Procurement and application engineering need both to match before a panel-build alternates review will pass: a same-frame drive with a different suffix typically changes the fieldbus interface, the I/O count, or the safety configuration rather than the power stage, and that is a wiring rework on the control side, not the power side. Weight lands at 2.72 kgs on this build — light enough that a single tech mounts it on a DIN rail or in a cabinet cutout without rigging, and well within the cabinet loading budget for a retrofit spare.
