Eaton’s Bussmann series Positive Temperature Coefficient (PTC) resettable devices 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 device will return to a low resistance state and allow for continued operation.
