What this order code is
The ABB ACS355-03U-03A5-2+J400+K452 sits in the Motors & Motor Controls line as a Motor Drives entry within ABB's ACS355 micro drive family, listed at 0.55 kW on the manufacturer title line. The order code itself carries the option suffix pattern (+J400 +K452) that ABB uses for factory-configured variants — J400 and K452 typically denote specific firmware or interface options, but the option dictionary is not on this listing, so refer to the ABB variant decoder against the as-built nameplate when verifying fit.
Frame and handling
Listed weight is 1.36 kgs, consistent with a wall-mounted IP20 micro drive that a single technician can position on the backplate without lifting aids. No mounting cutout or dimensional drawing appears in this listing, so the panel builder should pull the mechanical drawing from the ABB ACS355 installation manual against the frame size derived from the 03A5 current rating before drilling.
Cross-reference against ACS310 siblings
Three ACS310 alternates are on record — ACS310-03U-02A6-4, ACS310-03U-06A2-4, and ACS310-03U-08A3-2 — and none is a drop-in for an ACS355 panel. The 02A6 and 06A2 entries use the -4 suffix while the 08A3 entry uses -2, and all three carry a 1.36 kgs or 1.41 kgs weight distinct from this ACS355 order code.
Sourcing posture
No production-status or lifecycle entry is on file for this order code, so do not treat it as confirmed obsolete or active — specify it to the exact option string +J400 +K452 on the RFQ and let the channel confirm availability against the as-built variant code.
