Product details

What landed on the BOM

The ACS550-U1-078A-4+B055+K462: It sits in the Motor Drives class — Drives under Motors & Motor Controls — which is where the ACS550 family has always been specified for general-purpose fan, pump and conveyor applications.

Same-series alternate the planner actually weighs

The ACS550-U1-096A-4 is a same-series, same-U1-frame alternate at 19.96 kgs, with the caveat that the +B055 and +K462 suffix is not automatically carried and the configuration has to be reconciled against the as-built drawing.

Sourcing posture for a configured suffix string

The base order code ACS550-U1-078A-4 is a long-running ABB drive, and the configured string with +B055 and +K462 is what was specified into the BOM; the configuration is the part, not an accessory.

Frequently asked questions

Is the ACS550-U1-096A-4 a drop-in for a panel built around ACS550-U1-078A-4+B055+K462?

It is a same-series, same-U1-frame alternate at 19.96 kgs, but the option-code suffix on the configured part (+B055, +K462) is not automatically carried by the alternate order code — the configuration has to be reconciled against the as-built drawing before a swap.
