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. Whereas a fuse will completely stop the flow of current which may be desired in critical applications after most similar overcurrent event ptcs continue to enable the equiment to function except in.
