The fuse holder refers to the holder used to install the fuse. The fuse holder can be divided into: panel mount fuse holder, PCB mount fuse holder, lead type fuse holder, rail type fuse holder, and automobile fuse holder. When the circuit breaker of the fuse holder is connected to the power supply, the temperature of the melt will increase due to the heat generated by the conversion of the current. In the process of loading all the normal working current or the agreed load current, its current The calorific value of the disease and the calorific value transmitted through the melt, the radiation source of the enclosure and the surrounding environment can slowly reach equilibrium. This article mainly talks about the type, size and function of the fuse holder.

Common Types of 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 when installed. 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.

Fuse holder size

This fuse holder is divided into large fuse holder, medium fuse holder and small fuse holder. That is to say, these three are different in model. Naturally, the function is not the same. For example, a large fuse holder can play a larger role. In use, it is necessary to judge according to the specific situation in order to reasonably choose the correct fuse holder.

Function of the fuse holder

1. With protection function

The primary function of the fuse holder is the protection function, that is, it plays a certain role when it is necessary 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

At the beginning of the article, we have already mentioned that 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.
