A base and a fuse carrier make up this sort of fuse. The fixed contacts, to which the incoming and outgoing phase wires are attached, are supported by the porcelain base. The fuse element is held between the terminals of the fuse carrier, which is likewise made of porcelain. According to need, the fuse carrier can be put into or taken out of the base.
Advantages of kit kat fuse.
1. This removable fuse carrier makes it possible to change the fuse element without taking the chance of touching a live component.
2. The expense of replacement is little.
Disadvantages of kit kat fuse.
1. By using the wrong size fuse wire or the inappropriate substance, there is a chance of mistake.
2. Because of its low breaking capability, this type of fuse cannot be employed in circuits with severe fault levels.
3. As a result of the element's constant heating, the fuse element is prone to damage from oxidation. As a result, over the time, the fuse's current rating decreases. Hence, the fuse can carry less current than it was designed to.
4. As the ambient conditions have an impact on the protective capacity of such a fuse, it is unknown.
5. The fusing current greatly depends on the fuse element's length, So accurate calibration of the fuse wire is not achievable.
Despite having a 500A maximum rated current, Kit-Kat fuses have a lower breaking capacity. Therefore, only household and lighting loads may be protected by this type of fuse.
