Circuit protection

PTC resettable devices

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, helping to 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 continued operation.
