What the line item is
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.
Sourcing posture
Compliance document packs (RoHS, REACH, UL, IEC) are not listed alongside this code in the available record, so the RFQ response is where those papers need to be requested rather than assumed.
