Product Details

Thermal fuses are mainly used for overload protection. If the fuse is correctly placed in the circuit, the fuse will automatically cut off the current when the current abnormally rises to a certain Value and temperature, which protects the safe operation of the circuit.The metal case thermal fuse cut off is also called RY series, which is Organic chemical type, metal cylindrical shape, 65 -300 rated operating temperature, 10/15/16 / 20A rated current.

When the material and shape of the Thermal fuse are determined, its resistance R is relatively determined (if its temperature coefficient of resistance is not considered). When current flows through it, it generates heat, and its heat generation increases with time. The magnitude of the current and resistance determines the rate of heat generation. The structure of the fuse and its installation condition determine the rate of heat dissipation. If the rate of heat generation is less than the rate of heat dissipation, the fuse will not cutt off. If the rate of heat generation is equal to the rate of heat dissipation, it will not melt for a long time. If the rate of heat generation is greater than the rate of heat dissipation, more and more heat will be generated. And because it has a certain specific heat and mass, the increase in its heat is reflected in the increase in temperature. When the temperature rises above the fuse's melting point, the fuse will blow and cut off.
