Do QO and QOB breakers come as standard with a UL Listed 48 Vdc rating?

Product Line:
QO / QOB MCB's

Resolution:
Due to changes in UL 489, only 2p, 10 to 60 A QO/QOB breakers with a 5272 suffix are rated up to 48 Vdc. They have a 5 kAIC rating on a 48 Vdc system. They also have the 48 Vdc rating listed on the UL label.

Note: This does not include breakers ending in GFI, EPD, EPE, AFI, CAFI, DF, AF, or AFGF. DC rated breakers with these suffixes are not available
