A resettable fuse or polymeric positive temperature coefficient device pptc is a passive electronic component used to protect against overcurrent faults in electronic circuits the device is also known as a multifuse or polyfuse or polyswitch they are similar in function to ptc thermistors in certain situations but operate on mechanical changes instead of charge carrier effects in semiconductors.

The fuse melts open interrupting the current flow and the ptc changes from a low resistance to a high resistance to limit current flow.
