Working principle of ceramic fuse
When the material and shape of the fuse are determined, its resistance R is relatively certain (if the temperature coefficient of its resistance is not considered). When current flows through it, it will generate heat, and its calorific value will increase with time. The size of current and resistance determines the speed of heating, and the structure and installation of fuse determine the speed of heat dissipation. If the heating speed is less than the cooling speed, the fuse will not blow. If the speed of heating is equal to the speed of heat dissipation, it will not fuse for a long time. If the heating speed is greater than the cooling speed, more and more heat will be generated. Because it has a certain specific heat and mass, the increase of its heat is manifested as the increase of temperature. When the temperature rises above the melting point of the fuse, the fuse blows, which is the working principle of the fuse.

The discovery of electricity is great. It not only brings convenience to our production and life, but also makes great contributions to our scientific and technological development and social progress. However, we have to say that electricity is still a dangerous thing. The application of fuse ensures the use of electricity to a certain extent, although there are still some hidden dangers, but it also greatly reduces the danger. Ceramic fuse is a widely used fuse. Knowing the price suggestions of some manufacturers and some principles about it can help you understand and use it effectively.
