What Are the Reasons for Frequent Blowing of Automotive Fuses?
1 Answers
Automotive fuses frequently blow mainly due to short circuits in the car or excessive current causing overheating of the wires. Here is a related introduction to automotive fuses: 1. Fuses can be divided into two types: Tube fuses and wire fuses, with wire fuses being more common. Charging fuses and ignition switch power fuses can handle large currents of 100–200A, so it is absolutely not allowed to replace them with fuses of a larger capacity than specified. When a fuse blows, the cause must be carefully investigated, and the fault must be completely eliminated. 2. The function of fuses: Fuses are used to protect local circuits. The commonly used fuses in automobiles can be divided into tubular and blade types based on their shape. Fuses can withstand a long-term rated current load. Under a 25% overload, they will blow in about 3 minutes; under a 100% overload, they will blow in less than 1 second.
