　　The rated current of the melt is not equal to the rated current of the fuse. The rated current of the melt is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the melt and determined in conjunction with the main electrical appliance.

　　The fuse is mainly composed of three parts: the melt, the shell, and the support, among which the melt is a key component that controls the fusing characteristics. The material, size, and shape of the melt determine the fusing characteristics. Melt materials are divided into two categories: low melting point and high melting point. Low melting point materials such as lead and lead alloys have a low melting point and are prone to melting. Due to their high electrical resistivity, the cross-sectional size of the melt produced is larger, and the metal vapor generated during melting is more. They are only suitable for fuses with low breaking capacity. High melting point materials such as copper and silver have a high melting point and are not easy to fuse. However, due to their low electrical resistivity, they can be made into smaller cross-sectional sizes than low melting point melts. They produce less metal vapor during melting and are suitable for fuses with high breaking capacity. The shape of the melt can be divided into two types: filamentous and banded. Changing the shape of the variable cross-section can significantly change the fusing characteristics of the fuse. Fuses have various different fusing characteristic curves, which can be suitable for the needs of different types of protection objects.

The Protection Application of Self Recovery Fuses in Electric Toys.fast acting fuse bussmann

　　　　With the development of technology and social progress, people are paying more and more attention to the intellectual development of infants and young children. Various educational toys are springing up one after another, including electric and non electric ones, with thousands of types and varying quality requirements.　　When people purchase toys, they often pay more attention to their playable functions and neglect their safety. Many toy quality issues are only taken seriously when accidents occur, but it is too late and have already caused harm to people, some of which may last for a lifetime.　　In foreign countries and particularly developed countries, the safety of electronic toys is the most important. Regardless of certification, testing, research and development design, customer requirements, etc., the first consideration is safety, followed by the functions of toys, especially electric toys. Therefore, the safety protection of toys is the primary issue. In clause 3.6.2 of th

youtube fuseschool.Does the fuse have a resistance value?

　　　　Fuses have resistance values, but in fact, even wires have resistance. However, the resistance of the wires is very small (the nature of the conductor), which is usually ignored in general circuit calculations. However, the resistance of a fuse is significantly higher than that of an equally long wire, so that it can protect the circuit.　　The fuse is marked with "5A 250V", indicating that the maximum current allowed for Shenzhen fuses is 5A, which is called the rated current; The maximum voltage allowed to pass through is 250V, which is called the rated voltage. If the current or voltage exceeds the rated value, the fuse will blow, causing the circuit to open, thus protecting the consumer (without a fuse, the consumer may be burned out).　　The principle of fuse blowing is Joule's law. Joule's law: The heat generated by an electric current passing through a conductor is proportional to the square of the current, to the resistance of the conductor, and to the time it is energized.

Experience in selecting self recovering fuses

　　　　Do you have any good experience to share in selecting self recovering fuses? Self recovery fuse is an overcurrent electronic protection component, which is made of high molecular weight organic polymers under high voltage, high temperature, and sulfurization reaction conditions, mixed with conductive particle materials, and processed through special processes.　　The main function of a self-healing fuse is to provide overcurrent protection in electrical appliances. Therefore, self recovering fuses have parameters such as withstand voltage, withstand current, maintain current, and action time. Therefore, it is necessary to choose a suitable self recovery fuse based on the voltage, current, and protection current of the product used.　　The selection method for self recovery fuses is as follows:　　Firstly, determine the maximum ambient temperature, operating current, maximum operating voltage, required protection current, and action time parameters for the protected circuit to operate nor

What is the method for replacing car fuses?resettable 30 amp fuse

　　　　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
