Since this material has a certain conductivity, a current will flow through it. When an overcurrent passes through the nonlinear PTC thermistor, the generated heat will expand it, so that the carbon black particles will separate and the resistance will rise. This will cause the non-linear PTC thermistor to generate heat faster, expand more, and further raise the resistance. When the temperature rises to a certain extent, the resistance change is remarkable, so that the current is remarkably reduced. The small current flowing through the thermistor is sufficient to keep it at this temperature and in a high resistance state. When the fault is removed, the thermistor is contracted to the original shape to link up the carbon black particles again, so that the nonlinear PTC thermistor is quickly cooled and returns to the original low-resistance state, and the nonlinear PTC thermistor can work circularly.
