The specification of automobile fuse holder is generally2A span>to40A, its amperage value will be marked on the top of the fuse. If the fuse is burned out and the amperage value cannot be recognized, we can also judge by its color, standard: 2A< span style="font-family:宋體;font-size:12pt;">grey,3APurple,4Apink,5AOrange,7.5ABrown, etc.

Under normal circumstances, a car will have two fuse boxes, one is located in the engine compartment, in the process of using the main It is the fuse responsible for the external electrical appliances of the car, compared to the car's horn, glass washer, control unit, ABS, headlights, etc.

In the process of using the car fuse holder, it is generally not necessary to carry out special maintenance, but it should be noted that the insurance to protect the fuse If the cover is lost, be sure not to expose the fuse to avoid short circuiting of the fuse.

We know that a good fuse must have three functions at the same time: fuse protection function, surge resistance function and safety breaking function, and the fuse resistance is in the None of these three aspects can fully play a good function. Although the fuse resistor has the action of overcurrent fuse, it cannot really achieve the same function as the fuse. In most applications, it is incorrect to replace the fuse with a fuse resistor in order to reduce costs.
