PTC Resettable fuses

Eaton’s Bussmann series Positive Temperature Coefficient (PTC) resettable fuses offer overcurrent protection in a wide variety of applications.  They feature a polymer based construction that provides exponentially increasing resistance during fault conditions to form a tripped state which helps protect downstream circuit components from damaging overcurrents.  Upon removal of the fault, the PTC resettable fuse will return to a low resistance state and allow for continued operation.
