Frequently asked questions
Is the ACS550-U1-03A3-4 a drop-in second source for a panel specced around ACS550-U1-096A-4?
No. The 096A-4 is listed at 19.96 kg versus 5.90 kg here — that is a different frame size with different mounting and DC-bus hardware, not an interchangeable alternate.
How is this part sourced?
Quoted to order against an RFQ through the ABB channel, with independent surplus and refurb supply available for the 5.90 kg frame.
