Yes, NF panelboards and EDB, EGB, EJB breakers can be used on other voltage systems, with the exception of breakers with EPD suffix (equipment ground fault protection). The EPD module will only function on a 480Y/277V system. Following is the list of approved voltage systems 
  • 3P4W, 480Y/277Vac
  • 3P4W, 208Y/120Vac (do not use EPD breakers)
  • 3P3W, 240Vac Delta
  • 3P3W, 240Vac Corner Grounded Delta (grounded B phase)
  • 3P4W, 240/120Vac High Leg Delta (do not use EPD breakers)
  • 1P3W, 120/240Vac (do not use EPD breakers)
