PPTC self recovery fuse (plug-in) is a high polymer positive temperature coefficient thermistor. Compared with ceramic PTC thermistor, it is suitable for overcurrent and overload protection circuit with high current. When in use, PPTC self recovery fuse with appropriate rated current is selected to be connected in series in the circuit to be protected. When the line fails and the current increases greatly, PPTC changes from low resistance to high resistance due to its own heating, so as to reduce the current in the circuit and protect the circuit. When the fault is eliminated, the temperature of PPTC itself decreases, returns to the initial resistance, and the line returns to normal operation.
