When it comes to fuses, we are all very common, so by definition, the fuse box is the box in which the fuse is installed, but this is wrong. There are certain misunderstandings in our general habitual understanding. The fuse box here refers to the box in which the fuse is installed (also It is called fuse holder) Generally, in order to facilitate the installation of fuses, we will make the fuse box have some characteristics, such as waterproof, fireproof and high temperature resistance, etc. They can be divided into lead-type fuse boxes and automobile fuse boxes according to their different shapes. . General injection molding materials for fuse boxes are: plastic, nylon, bakelite, PBT engineering plastics.

The material of each fuse box is different, which leads to different degrees of high temperature resistance. Therefore, in the process of choosing a fuse box, we should consider the current size of the fuse used, the size requirements of the fuse, and so on.

The larger the fuse current is, the larger the wire should be used in the matching wire with the fuse box, otherwise it will cause the fuse box and the wire to heat up and cause fire and other dangers.
