What it is and where it sits
MPN ACS380-040C-02A6-4+K475 decodes as an ACS380-series drive; base code 040C-02A6-4 carries the frame/rating slot, and the +K475 suffix adds the factory-fitted option bundle. Listing title: ACS380-040C-02A6-4+K475 - ACS380 SERIES by ASEA BROWN BOVERI. For panel layout the unit is listed at 1.81 kg — a single-handed swap during a line-down event, but still worth a second pair of hands on a DIN-rail or wall-mount bracket above head height.
How the +K475 variant compares to the +K490 sibling
Per peer row, the closest functional peer is the ACS380-040C-02A6-4+K490: same 040C-02A6-4 base code, same 1.81 kg, same Drives / Motor Drives placement. The only delta in the ledger is the option suffix itself. Because the base frame, weight, and category placement carry through unchanged, a panel specified around the +K490 variant should accept the +K475 as a drop-in on the mechanical side; the open question — which the listing alone does not answer — is whether the +K475 option bundle covers the same I/O, fieldbus, or safety functions the +K490 was specified for. That check has to happen against the option-code definitions in the ACS380 ordering documentation before a one-for-one swap is signed off.
Where this drive class is used
ACS380-series drives sit in the compact-machinery segment of ABB's drive portfolio — the class typically feeds small three-phase induction or permanent-magnet motors in conveyors, pumps, fans, and packaging machinery where a panel-mount VFD with onboard fieldbus options is the practical fit.
Sourcing posture
Spec: ABB MPN ACS380-040C-02A6-4+K475, brand abb. Sourcing path: RFQ against the MPN; no production-status or lifecycle row present, so an active-production assertion is omitted.
