company news about How to choose a suitable fuse?

        A suitable fuse should meet at least three requirements: it must be broken when it should be broken, it must not be broken when it should not be broken, and safety must be guaranteed during the breaking process.

        The first function of the fuse is the protection function, that is, the fuse should play a role when protection is needed, which is what we need to consider first when choosing a fuse.

        The second function of the fuse is the load-carrying function, which is commonly referred to as the pulse resistance capability, which is an important parameter that must be considered at the same time when we choose the fuse.
        The third function of the fuse is the safety function. A high-quality and reliable fuse should ensure safety before, during and after its action, that is, it can be turned on and fused safely. The main technical indicator that can guarantee this requirement of the fuse is the breaking capacity.

        In summary, proper fusing characteristics and rated current; sufficient and reasonable melting heat value; and suitable breaking capacity, rated voltage and safety certification are necessary conditions to ensure the main function of the fuse, only when these three conditions are met On the basis of the protection performance and the pulse resistance, we can coordinate the constraints between the protection performance and the pulse resistance, and seek the most reasonable balance, so that we can make a judgment: such a fuse is a high-quality and reliable fuse.
