A good fuse has these three functions.bussmann radial fuse
The first function of a good fuse is maintenance. In general, the additional current of a fuse must be greater than the normal operating current of the circuit and have a certain overload capacity, but the margin cannot be too large. The second function of a good fuse is its load-bearing function. This is commonly referred to as the ability to withstand pulses. During the use of fuses, there is a greater chance of normal current fluctuations or instantaneous pulses than fault overcurrent, which is particularly important for the use of fuses. The third function of a good fuse is its safety function. A high-quality and reliable fuse should ensure safety before, during, and after its operation, that is, safely conducting and safely fusing. In summary, appropriate fusing characteristics and additional current; Satisfactory and reasonable melting heat energy value; Proper breaking ability, additional voltage, and safety certification are necessary conditions to ensure the main functio
