I am working on an internal document showing examples of the voltage Rating for products that have different power sources.
Currently, our North American 3-phase devices are rated 230V 3~, and our EU versions are rated 400V 3~. But in the future, we may wish to use the Neutral to which the Rating becomes more complicated. Thanks for the input.
