1. Maintenance Function
The primary function of a fuse holder is maintenance, serving as a safeguard when electrical appliances or fuses require maintenance. Generally speaking, fuses are rated for currents higher than the normal operating current of the appliance and also have a certain overload capacity. However, if the current margin is too high, the fuse's maintenance function will be compromised. In this case, the fuse holder fulfills its protective function, taking on the role of the fuse itself.
2. Carrying Function
As mentioned at the beginning, a fuse holder is an accessory used to hold fuses. Placing various fuses in the correct order prevents them from being disturbed. Furthermore, as a dedicated place for fuses, it greatly facilitates subsequent locating and repair of any issues. Therefore, it can be said that a fuse holder serves as a carrier, facilitating subsequent use and maintenance.
