yes it is wired for both 240 volts and 208 volts
the reason why dual rated because on single phase system it is normally 120/240 volts and on three phase wye system is 120/208 volt.
the 208 volt is common with large apt or home near hevey commercal system which it allready have 208 volt there.
keep in your mind the wattage do reduce some how on 208 volt system genrally about 20 to 25% less wattage than straght 120/240 volt single phase system
Merci , Marc
