　　(1) Precautions for using fuses: ① The protective characteristics of the fuse should be compatible with the overload characteristics of the protected object. Considering the possible short-circuit current, a fuse with corresponding breaking capacity should be selected.

　　② The rated voltage of the fuse should adapt to the line voltage level, and the rated current of the fuse should be greater than or equal to the rated current of the melt.

　　③ The rated current of each level of fuse melt in the circuit should be matched accordingly, and the rated current of the previous level of melt must be greater than the rated current of the next level of melt.home energy storage system battery

　　④ The melt of the fuse should be matched according to the requirements, and it is not allowed to arbitrarily increase the melt or use other conductors to replace the melt.

　　⑵ Fuse inspection:

　　① Check whether the rated values of the fuse and melt match the protected equipment.

　　② Check the appearance of the fuse for damage or deformation, and check the porcelain insulation for flashing discharge marks.

　　③ Check if each contact point of the fuse is intact, tightly connected, and there is no overheating phenomenon.

　　④ Whether the fuse signal indicator is normal.

What are the principles for selecting fuses.resettable 15 amp fuse

　　　　1. Is the quality of the fuse qualified　　When choosing a fuse, it is important to determine whether the quality of the fuse is qualified. Unqualified fuses may have too many uncertain factors during use, such as not being able to operate under normal current and voltage or not being able to fuse in a timely manner when the circuit is overloaded. This can have adverse effects on the product's circuit and electrical appliances, and personal safety cannot be guaranteed. Therefore, when purchasing a fuse, it is necessary to check whether the product is qualified.　　2. Is the fuse model suitable for circuit operation　　There are many types of fuses. When choosing a fuse, it is necessary to first understand the normal circuit working current and voltage of the product, and then select appropriate fuse parameters. This way, the fuse can protect the circuit from being damaged by overload current when the circuit is overloaded.　　3. Breaking capacity of fuses　　A fuse must pay attention to its

The Matching Function of Self Recovery Fuse in Anti Reverse Connection Protection

　　　　Generally speaking, DC power circuits have protection requirements for anti reverse connection, and in many cases, protection is achieved by connecting anti reverse diodes in series. However, in some cases, anti reflection diodes are not suitable due to the series voltage drop. At this point, the self recovery fuse based on surge protection can be combined with one-way TVS to achieve anti reverse protection. As shown in Figure 6, when the DC power supply is reversed, the unidirectional TVS is directly connected, generating overcurrent, causing the to act quickly and limit the current. When applying this scheme, it is also necessary to consider the withstand voltage of and the power of TVS.　　self recovery fuses are widely used for overcurrent protection in power lines, communication lines, and various I/O input and output ports of electronic products in communication, security, industrial, automotive, consumer and other fields. It can effectively prevent product damage due to short

Reasons for the increasing importance of circuit protection components.china hs code for fuse

　　　　In daily life, electronic products are everywhere, and circuit protection has become increasingly important. In order to make circuits safer, engineers are constantly studying the safety and reliability of products. The main reasons for this are as follows:　　(1) With the demand for the development of electronic products, the functionality (integration) of ICs is also becoming stronger, and their "value" is naturally becoming more noble, so it is necessary to strengthen protection.　　(2) In order to reduce power consumption, reduce heat generation, and extend service life, the working voltage of semiconductor components and ICs is getting lower and lower. According to statistics from the American Semiconductor Industry Association, the current working voltage is around 1.5V, which will decrease to a lower level in the following years. Therefore, its ability to withstand overcurrent/overvoltage needs to adapt to new protection requirements.　　(3) There are more and more mobile electron
