The performance of fuses is affected by temperature

　　We know that fuses often generate heat during continuous operation, leading to an increase in surrounding temperature and thus affecting the performance of the fuse. Therefore, when selecting fuse models, we should pay attention to the influence of temperature.

　　The action of a fuse is directly caused by heat, so the ambient temperature must have an impact on the performance of the fuse. The ambient temperature here not only refers to the indoor or outdoor temperature around the electronic and electrical equipment, but more importantly, it refers to the temperature around the small environment where the fuse is located inside the machine during equipment operation. This will directly affect the performance of the fuse. Generally, the maximum atmospheric temperature will not exceed 500 ℃, but the small environment temperature inside the machine may even exceed 1000 ℃, which will have a significant impact on the performance of the fuse.home energy storage system battery

　　From this, it can be seen that the higher the ambient temperature, the faster the fuse (fuse) blows, which means its specifications have actually decreased.

　　Due to the influence of working environment temperature on the performance of fuses, when selecting fuses, we must also consider their actual working temperature. The fuse manufacturer should provide a reduction curve of the product under high temperature conditions, which can tell customers at what temperature the rated current of the fuse will be reduced to what percentage. For the temperature reduction rate of self recovery fuses, please refer to "How to Select Self recovery Fuses".
