Common types fuse holders
1. According to the type of installation
It can be mainly divided into two types: fuse holder and fuse holder. From the name of the fuse holder, we can know that it presents a tubular fuse holder, which is mainly erected during installation. The safety plate holder is installed in the way of patch installation.
2. According to the size of the fuse
It can be divided into three types: large fuse holder, medium fuse holder and small fuse holder. The current size used by different electrical appliances is different, and the use of fuses of different sizes can play a different degree of current blocking effect. With different specifications, the size of natural fuses will also be differentiated. For this reason, we have the three types of fuse holders mentioned above.
3. According to the material
There are two types of plastic fuse holders and bakelite fuse holders, which are the two most widely used in our daily life. As the name suggests, the fuse holder is made of different materials and used in different scenarios.
The function of the fuse holder
1. With protective function
The primary function of the fuse holder is the protection function, which is to play a certain role in the need to protect electrical appliances and fuses. Generally speaking, the rated current of the fuse is higher than the current used by our electrical appliances, and it also has a certain overload capacity. However, if our current margin is too large, it will cause the protection of the fuse. At this time, the fuse holder plays its protective role and acts as a fuse.
2. It has a bearing function
As we mentioned at the beginning, the fuse holder is an accessory used to place the fuse. Put all kinds of fuses on the fuse holder in a certain order, so as not to disturb the function of each fuse. At the same time, because it is a special place for placing fuses, it provides considerable convenience for finding and repairing subsequent problems. For this reason, we can say that the fuse holder has the function of bearing and is convenient for subsequent use and maintenance.
