How to choose Fuses?

Before choosing a fuse, if you know about the fuse and the product, you can avoid a lot of trouble when choosing a fuse. Next, what are the principles of choosing a fuse?

  1. Whether the fuse quality is acceptable
    When selecting fuses, it is important to check whether the quality of fuses is qualified. There are too many uncertain factors in the use of unqualified fuses, which can not work under normal current and voltage or fuse in time when the circuit is overloaded, which will have adverse effects on the product circuit and electrical appliances, and personal safety can not be guaranteed. Therefore, it is necessary to check whether the product is qualified when purchasing fuses.
  2. Whether the fuse model meets the circuit operation
    There are many types of fuses. When choosing a fuse, you should first understand the normal circuit working current and voltage of the product, and then select the appropriate fuse parameters. In this way, when the circuit is overloaded, the fuse can protect the circuit from being damaged by the overload current.
  3. Breaking capacity of fuse
    Attention must be paid to the breaking capacity of a fuse. Whether the fuse is slow breaking or fast breaking, whether it can be blown in time when the circuit is overloaded, if not, it indicates that the fuse has problems. Therefore, when choosing a fuse, we should understand the specific action standard of the breaking capacity of the fuse and measure whether it is applicable to the product circuit.
  4. Whether other factors affect the fuse
    When choosing a fuse, consider whether other factors will affect the operation of the fuse according to the unacceptable products. For example, the working environment temperature of the product, the size of the circuit space of the product, the current and voltage that the circuit of the product can withstand, the service life of the fuse, and the storage time of the fuse after production.
