Do you know the difference between fuses of different prices?


The price of fuses comes from different materials, different processes and different brand pricing.

The different qualities of high-voltage fuses are mainly reflected in the following aspects:

● Material quality: The quality of the shell and internal contact materials of the high-voltage fuse directly affects its performance and reliability. High-quality fuses are often made of high-strength insulating materials to ensure that they can withstand high-voltage current and the influence of the external environment. The contact material is usually made of metal with good electrical conductivity and high temperature resistance and corrosion resistance to ensure the stability and durability of current conduction.


● Breaking ability: High voltage fuses of different qualities have different cutting abilities. Cutting capacity refers to the maximum current value that the fuse can withstand and cut off. High-quality fuses generally have higher interrupting capabilities and can withstand higher current loads, thus better protecting electrical equipment and power systems.

● Fusing speed: Fusing speed is also an important indicator of the quality of high-voltage fuses. High-quality fuses have faster melting speeds and can quickly cut off the circuit when an overcurrent event occurs, effectively protecting electrical equipment. A fuse of poor quality may melt slowly, causing the electrical equipment to be overloaded for a long time, possibly causing damage.


● Effect stability: The quality of high-voltage fuses is also reflected in the stability of its effect. High-quality fuses are precisely manufactured and rigorously tested to work stably for a long time and have a low failure rate. Fuses with poor quality may suffer from performance degradation, fire hazard, poor conductivity and other problems after long-term use, and may even cause accidents.

To sum up, the quality differences of high-voltage fuses are mainly reflected in material quality, cutting ability, fusing speed and effect stability. Choosing high-quality high-voltage fuses can better protect electrical equipment and power systems and improve system reliability and safety.
