PPTC ------ Polymer resettable fuse is composed of polymer matrix and carbon black particles that make it conductive. Because the polymer resettable fuse is a conductor, a current will flow through it. When an overcurrent flows through the polymer resettable fuse, the heat (I2R) generated will cause it to expand. As a result, carbon black particles will separate and the resistance of the polymer resettable fuse will increase. This will cause polymer resettable fuses to generate heat faster and expand even more, further increasing resistance. When the temperature reaches 125 ° C, the resistance changes significantly, which reduces the current significantly. The small current flowing through the polymer resettable fuse at this time is sufficient to keep it at this temperature and in a high resistance state. After the fault is cleared, the polymer resets the fuse to its original shape and reconnects the carbon black particles, thereby reducing the resistance to a level with a specified holding current. The above process can be repeated multiple times.
The operating principle of the PPTC recoverable fuse is a dynamic balance of energy. The current flowing through the PPTC element generates heat due to the relationship of the PPTC. The generated heat is totally or partially radiated to the environment. Without the emitted heat, the PPTC element will be improved temperature.
The temperature during normal operation is relatively low, and the heat generated and heat radiated reaches equilibrium. The PPTC element is in a low resistance state, and the PPTC does not operate. When the current flowing through the PPTC element increases or the ambient temperature increases, but if the balance between the generated heat and the emitted heat is reached, the PPTC still does not operate. When the current or ambient temperature increases, the PPTC will reach a higher temperature. If the current or ambient temperature continues to increase at this time, the heat generated will be greater than the heat emitted, which will cause the temperature of the PPTC component to increase sharply. At this stage, a small temperature change will cause a significant increase in resistance. At this time, the PPTC component is at High resistance protection status.
