We have a customer who wants us to make an enclosure for them that has a 480/240V 3 phase circuit breaker. I know 480/277 V breakers are widely available, but I can't find any 480/240V breakers in any catalogues such as Cutler Hammer or Square D and I don't know how that voltage combination is possible mathematically. I don't know if this is a mistake on the customer's part or if these actually exist. I am leaning toward a mistake on the customer's part. Any thoughts?
