I just asked a Leader in machine tool and either a 460v or a 480v xformer will do but if it has a PLC,VFD or Soft Start try to stay at or above 460.What ever you can get cheaper or have in stock would be his main consern.Since you can,check what your 600v supply actualy is and go from there.A Poco owned xformer gives supplies us 640v and they won't repace it because we don't have any problems.
cheers
