What lands on the panel
The ABB ACS380-040C-09A4-4+K470+L534 is a configured ACS380-series motor drive from ASEA BROWN BOVERI, with the +K470 and +L534 option suffixes applied to the base 040C-09A4-4 frame. The order code carries the full configured string — base drive rating plus the +K470 and +L534 factory-installed options — so a substitute order has to match the suffix set, not just the bare current/voltage frame.
