company news about How to determine the safety function of fuse?

        The safety function of the fuse refers to that the high-quality and reliable fuse should ensure the safety before, during and after its operation, that is, safely conduct and fuse. The main technical index that can guarantee the requirement of fuse is the breaking capacity.

        Breaking capacity refers to the maximum current that the fuse can safely cut off the circuit. Generally, it refers to short circuit current. It means that the fuse must be able to break the circuit absolutely safely in case of short circuit current, that is, there will be no unsafe factors during the breaking process, such as continuous arcing, multiple conduction, breakage, splash, combustion, and even explosion. The breaking capacity of each fuse must be greater than or equal to the maximum short-circuit current of the protected circuit. The rated voltage of the fuse determines its withstand voltage and is also another indicator of the safety performance of the fuse. It can only be used in the circuit with the working voltage less than or equal to the rated voltage of the fuse. All countries and regions in the world carry out safety certification for safety components, and the safety certification of fuse is also essential for its safety function. The safety function of the fuse can only be met by selecting the fuse with sufficient breaking capacity and rated voltage and obtaining the necessary safety certification of the application area.
