We know that most fuse clips are made of metal, and the general domestic market requires them to be made of brass material. Because brass has the advantages of good stability and conductivity, choosing brass as a fuse clip is a good choice. After understanding the material of the fuse clip, we came up with the question: "So, are there any drawbacks to this material?" This answer is answered in the article "Analysis of Common Problem Cases of Fuse Clips", and today we are going to discuss related issues related to fuse clips within 20A. Firstly, when installing fuse clips, there may be situations where the elasticity of the fuse clips is poor. After installing and replacing the fuse several times, the elasticity of the fuse clip gradually deteriorates, and even ends up completely without elasticity. For such problems, it is generally recommended to use clamps made of phosphorous copper material, but they still have defects. Phosphorous copper has good toughness, but poor conductiv
Fuses can be divided into recoverable and disposable fuses. Recoverable fuses are commonly referred to as self restoring fuses. The biggest functional feature of these fuses is that after the circuit fault is eliminated, the fuse can be restored for recycling; The disposable fuse is what we refer to as a disposable fuse. It is disposable and cannot be reused and must be replaced. Its biggest functional feature is its high segmented ability, which can be divided into fast break and slow break fuses; Fast or slow break refers to the reaction speed of the fuse to the fault current. Today we will learn about the relevant parameters of a 0.3A self recovery fuse. There are two types of 0.3A self recovery fuses, domestic and imported. Currently, there are several models of domestic 0.3A self recovery fuses available in stock in Shenzhen, including A6-030, A16-030, A30-030, A60-300, A72-300, ASMD1812-030, ASMD1206-030, ASMD2016-030, and more. Among them, A6-030, A16-030, A30-030, A60-300,
1、 What is fuse resistance? Resistors and fuses are similar in material and construction, while fuse type resistors serve both functions and can be used as resistors to protect machine equipment in case of abnormal current. Due to its dual function, the cost is reduced accordingly. 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. 1.25A fuse resistance 2、 The function of fuse resistance Resistors and fuses are similar in material and construction, while fuse type resistors serve both functions and can be used as resistors to protect machine equipment in case of abnormal current. Usually, the resistance of a fuse is significantly higher than that of an equally long wire, so that it can protect the circuit. If the current or voltage exceeds the rated value, the fuse w
The voltage of a household circuit is usually 220V, and the current flowing through it is also very large. If a household circuit malfunctions or leaks, it will threaten human life safety. Therefore, in order to prevent this harm, we usually install an overload protection device in the main circuit of the household or install a fuse in the circuit. Some people want to know which one of these two has the greater effect? Next, the editor will answer for everyone. 1、 The function of leakage protector: Leakage protector, also known as leakage switch or leakage protector, is mainly used to protect equipment from leakage faults and potentially fatal personal electric shock. It has overload and short circuit protection functions and can be used to protect circuits or motors from overload and short circuits. It can also be used for infrequent switching and starting of circuits under normal circumstances. Leakage protectors can be classified according to their protection function, struct
Micro fuse is a type of fuse with relatively small volume. With the continuous development of domestic technology, many high-end and small products also need it. Currently, there are two common types of fuses in the market: micro circular fuse and micro square fuse. So what are its characteristics? The editor will now answer for everyone. 1. Characteristics of miniature fuses: Micro fuse is an electronic component suitable for insertion or welding into corresponding electrical appliances. It has small size, high sensitivity, and fast response, which can better reflect its advantages in circuits where the product space is not very large. 2. Application scope: Micro square fuses can be applied in set-top boxes, switching power supplies, power adapters, LCD TVs, computers, communication products, telephones, household appliances, various instruments, and various electronic components. 392 series miniature square fuse The series of plastic encapsulated fuse circular slow break ex
The low voltage current of the transformer is 453.6A (315KVA * 1.44=453.7A), and a fuse should be selected that is about twice as large. The high-voltage current of the transformer is 12.6A (315 * 0.04=12.6A), and a fuse of 2-2.5 times should be selected. The content in parentheses is a simple calculation of the high and low voltage currents of transformers. Due to the fact that the primary fuse of the transformer is used for short circuit protection (it cannot protect against overload on the low-voltage side), it is usually selected at a ratio of 1.5-2 times. As the load is only 270A, it is evident that there is no problem with heavy load startup. The load current is only 270A, so choosing 300A or 400A is sufficient. If the capacity of a single motor carrying a load on a transformer is close to the capacity of the transformer, when selecting a secondary side fuse, a fuse specifically designed to protect the motor should be selected, and the size should also be selected accordin
