The full name of 3C certification is "Compulsory Product Certification System", which is a product qualification evaluation system implemented by the Chinese government in accordance with laws and regulations to protect consumer personal and national safety, strengthen product quality management, and implement it. The so-called 3C certification is the China Compulsory Certificate system. It should be noted that the 3C mark is not a quality mark, but rather a fundamental safety certification. The "CCC" certification mark is divided into four categories The current "CCC" certification mark is divided into four categories, namely: 1. CCC+S safety certification mark; 2. CCC+EMC electromagnetic compatibility certification mark; 3. CCC+S&E safety and electromagnetic compatibility certification mark; 4. CCC+F fire certification mark; China has implemented the National Compulsory Certification System (CCC) since May 1, 2002. Compulsory certification is implemented for produc
Temperature controlled fuses are mainly used for circuit maintenance. When the temperature of household appliances exceeds the rated temperature of the fuse, they will automatically open the circuit breaker to avoid damage caused by excessive temperature. According to different composition methods, which types can temperature controlled fuses be classified? How to apply it correctly? Let's take a look! 1. Organic type temperature control fuse. It consists of moving contact points, melt, and torsion springs. The principle is to improve the fluidity of the surrounding environment during operation, melt, weaken the ductility of the torsion spring, cause the left line to separate from the moving contact point, disconnect the current, and disconnect the circuit. 2. Ceramic tube type temperature control fuse. This type of fuse is famous for its insulated porcelain tube. During operation, the temperature increases, causing the mixture to evaporate. After the dissolution point, the int
Many electrical appliances in car circuits are connected with wires of different colors, and fuses cannot be ignored. Fuse is a commonly used name and is referred to as Fuse in national standards. The function of a fuse is to protect circuits (circuits) and electrical equipment. Next, I will provide a detailed introduction to the differences in the size of automotive fuses? Let's learn more together. A car fuse is a type of current fuse. When the circuit current exceeds twice the rated current of the fuse, it will fuse within a few seconds, providing circuit protection. Commonly used for overcurrent protection in automotive circuits and industrial equipment. Automotive fuses can be divided into large, small piece fuses, and medium piece fuses. The rated current range is 1-40 amperes (a) to 30-120 amperes (a), and the rated voltage is 32 volts (V). The fork bolt fuse can be divided into small fork bolt fuse and large fork bolt fuse. The rated current is 30-150 amperes (a) to 40
A car fuse holder is a type of current fuse. In the application process, when the current of the power circuit exceeds its additional current abnormally, its fusing has the practical effect of maintaining the power circuit. Automotive fuse holders are commonly used for overcurrent maintenance of automotive power circuits and can also be used for overcurrent maintenance of industrial equipment. In the car power circuit of the car fuse holder, many power facilities will be connected to each other through cables of different colors. Among them, the most important one cannot be ignored is the fuse. The fuse holders provided by the automotive fuse holder supplier include: new plug-in fuse holders, medium size plug-in fuse holders, and small plug-in fuse holders. The above are common. The use of fuse holders depends on their own suitability. The key depends on the size, appearance, and functionality of the device. If the electrical equipment does not work during use, it may be caused b
With the digitization and digitization of automotive electrical equipment. The improvement of mechanical equipment and the miniaturization of fuses have resulted in an improvement in the total number of fuses used in each vehicle. Let's take a look at the purpose and specifications of car fuses. The main uses of automotive fuses are: 1. At every critical link (or component) of the car route, it is usually equipped with a plug-in or cylindrical shape. Pin like porcelain. Unique commercial insurance, such as junction boxes. There are various varieties with different purposes. 2. The commercial insurance installation of general plugins is located in areas that are conducive to installation, disassembly, and replacement. In areas where the working voltage (current) of the line fluctuates less, except for special circumstances, it is generally not easily damaged and maintenance is more convenient. 3. Various commercial insurance car companies have different methods of formulating th
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
