The ABB ACS355-03U-04A1-4+J400+ K475 is a general-purpose micro drive configured for a 3-phase 380-480 V supply, carrying the +J400 and K475 option suffixes that ship with the base 04A1-4 frame. The unit weighs 1.36 kgs, which is a single-hand wall-mount load for a controls integrator — relevant for panel-prep, never a selection parameter.
