What you're holding
The ABB ACS380-040C-12A6-4+K475 is the 040C-frame member of ABB's ACS380 series of Motor Drives. The +K475 suffix is part of the order code as printed on the nameplate, not a separate option — the panel builder, the stockroom, and the RFQ all need to land on this exact string, including the plus sign and the four-digit suffix. Category placement is Drives / Motor Drives under the broader Motors & Motor Controls tree. It is a general-purpose drive for compact motor control, not a soft starter, servo, or DC drive — frame size and the 040C designation put it in ABB's compact-wall-mount tier.
Frame and footprint — where it drops in
The ACS380 040 frame is a shared mechanical platform across the family. The same-frame sibling ACS380-040C-02A6-4+K490 lists the identical 1.81 kg mass in the same Drives / Motor Drives slot, so footprint, depth, and mounting pattern are unchanged — only the current class and the +K suffix differ. A cabinet laid out around the +K490 variant accepts the +K475 mechanically. Broader 040-frame siblings ACS380-040S-06A9-2 and ACS380-040S-04A0-4 carry the same 1.81 kg listing and the same Drives sub-category, which is the panel-builder signal that the 040 enclosure is a uniform platform: cooling geometry, gland-plate footprint, and EMC ground-bonding locations are consistent across the suffix variants.
