Frequently asked questions

What is the closest functional second-source for the ACS550-U1-038A-4+B055?

The closest peer in the same series is the ACS550-U1-09A0-6 (8.62 kg). Both are ACS550-U1 frame drives, but the -09A0-6 is a 6 A variant at a different voltage class (likely 600 V class). They are not drop-in replacements without verifying voltage and current ratings for the specific motor load.

Will the ACS550-U1-038A-4+B055 drop into a panel specified around the ACS550-U1-09A0-6 without rewiring?

Not without verification. Both share the ACS550-U1 frame, so the mechanical footprint and gland-plate layout are likely identical. However, the -038A-4 is a 38 A, 400 V class unit, while the -09A0-6 is a 6 A, 600 V class unit. Power wiring, fusing, and motor cable sizing differ. Always compare the nameplate ratings before swapping.

What compliance documentation does ABB provide for this drive?

The evidence does not list specific compliance documentation (RoHS, REACH, UL, IEC) for this order code. Standard ABB ACS550-series drives typically carry CE and cULus marks, but confirm with the supplier at RFQ time.
