Well I guess if you were being pedantic you could say it depends if the 3phase appliance is wired star or delta. If it's star you have 3 elements wired from each of the 3 actives to neutral, so all of them are still 240v.
In delta there's no neutral connection and each element goes between different combinations of actives, so all 3 are 440v
