　　A fuse is an electrical component installed in a circuit to ensure safe operation of the circuit. When the circuit malfunctions or is abnormal, it may burn the circuit or even cause a fire. Some fuses have a blown indicator device, which is used to indicate that when the fuse is activated (blown), it undergoes a certain appearance change and is easily detected by maintenance personnel. So what are the components of a fuse?

　　1. Electrode

　　Usually, there are two important components that are connected between the melt and the circuit. They need to have good conductivity and should not generate significant installation contact resistance.

　　2. Melt

　　It is the core of a fuse and plays a role in cutting off the current when it is blown. Fuses of the same type and specification should have the same material, geometric dimensions, and resistance values as small and consistent as possible. It is important to have consistent fusing characteristics.

　　3. Bracket

　　The melt of a fuse is generally thin and soft, and the function of the bracket is to fix the melt and make the three parts a rigid whole for easy installation and use. It needs to have good mechanical strength, insulation, heat resistance, and flame retardancy, and should not produce phenomena such as breakage, deformation, combustion, and short circuit during use.

Selection steps for self-healing fuse PPTC.plug in mcb for old fuse box

　　　　The self-healing fuse PPTC is a type of overcurrent electronic protection component, which is made by adding conductive particle materials to a polymer organic polymer under high pressure, high temperature, and vulcanization reaction conditions, and processed through a special process. Self recovery fuse (PPTC: Polymer self recovery fuse) is a positive temperature coefficient polymer thermistor used for overcurrent protection and can replace current fuses. When the circuit is working normally, its resistance value is very small (voltage drop is very small). When the circuit experiences overcurrent and causes its temperature to rise, the resistance value sharply increases by several orders of magnitude, reducing the current in the circuit to below the safe value, thus protecting the subsequent circuit. After the overcurrent disappears, it automatically returns to a low resistance value. The above is the working principle of a self recovery fuse.　　Chip self recovery fuse　　Most people

Precautions for using fuses

　　　　Using a fuse that is too small can easily burn out and cause power outages, while using one that is too large may cause damage to electrical equipment. So for safety reasons, to ensure the "safety" of the fuse, the following points should be noted:　　(1) Do not use fuses that are too thin. Using thin fuses can easily cause the normal current passing through to burn out, resulting in unnecessary power outages;　　(2) Suitable fuses must be selected and used, and the melting current of fuses is usually 1.5 to 2.0 times the rated current. If the total power of all appliances in a household exceeds 1100 watts during normal electricity use, choose a 5 ampere fuse and use a 20 gauge fuse with a diameter of 0.98 millimeters. When the current exceeds 7.5 amperes to 10 amperes, the fuse will automatically melt to achieve protection;　　(3) When installing fuses on power switches, live operation is not allowed. The power switch should be pulled open to disconnect the power supply;　　(4) Wrap the f

Fuse resistance.demand lighting fuse

　　　　Resistors and fuses are similar in material and construction, but their cost is reduced due to their dual function. Fuse resistors can be divided into: metal film fuse resistors, fuse type wound resistors, and fuse type cement resistors. There are several types of power: 1/4W, 1/2W, 1W, and 2W. As the power increases, the appearance size of the product will continue to increase.　　The resistance value of fuse resistance is generally small, mostly less than 1 ohm, and often acts as a sampling resistor in the circuit. At the same time, it plays a role in the occurrence of surges or other situations where large currents are generated and the circuit needs to be protected. Fusing causes the circuit to break and has a protective effect.　　At the same time, most of the fuse resistors are chip type, with relatively stable performance. They are commonly referred to as Jiebixin fuse resistors, which are also known as Jiebixin chip fuse resistors. There are two types of products: fast fuse and

Will plug-in fuses be phased out?resettable ptc fuse

　　　　In fact, this is not the case. Although patch fuses have a wider range of applications than plug-in fuses, there is also a high demand for plug-in fuses in the market. Both types of fuses, patch and plug-in, have their own advantages. For different products, selecting the right one can maximize the effectiveness of the fuse. Currently, plug-in fuses will not be eliminated.　　Taking self recovery fuses as an example, the volume of patch based self recovery fuses is different from that of plug-in based self recovery fuses. Plug-in type fuses have a relatively larger volume and are generally used in circuits with low working voltage and high working current, such as power converters, motorcycles, automobiles, computer power supplies, micro motors, computer interfaces, CPUs, and other fields. And patch type fuses are mostly used in many electronic products and in many circuit boards such as mechanical equipment.　　With the development and progress of technology, fuses are not only limite
