Selection Techniques and Installation Process of Chip Fuses
The fusing current of patch fuses is 1.5 to 2.0 times the rated current. When electrical equipment is in normal use, its fuse will not blow. When the current in the circuit exceeds 5 times its rated current, it will automatically fuse to provide protection. If the fuse of the electrical equipment blows during normal use, it indicates that the current in the circuit exceeds the rated value. Therefore, the cause should be promptly investigated.
During the installation process of patch fuses, it is necessary to first pull off the switch on the distribution board, cut off the power supply, and preferably use an electric pen to test whether there is power before operating. For fixing screws and washers, copper should be used instead of temporary iron, as iron can easily rust over time and lead to poor contact. When tightening the fuse, do not use too much force to prevent the fuse from being flattened and causing a decrease in cross-sectional area, rated current, and fusing current, which may not provide the necessary "safety" effect.
The patch fuse should not be too loose to a certain extent, mainly because excessive looseness can cause excessive contact resistance at the joint and cause accidental disconnection. After a fuse blows, it is best to ask a certified electrician to first investigate the cause. Users should not install it without authorization, and copper or iron wires should not be used to replace the fuse. This is very dangerous because copper or iron wires cannot cut off the current, and on the contrary, it can cause excessive heating and burning of wires and equipment, and even cause a fire.
Selection Techniques for Chip Fuses
1. Normal current: Firstly, we must know the fuse that flows through the circuit chip used in normal current. Usually, we need to reduce the difference between the predetermined amount and then follow the selection principle: the normal current must be less than the rated current and the product's derating factor.
2. Fusing current: According to UL standard requirements, patch fuses (fuses) should be able to quickly operate at twice the rated current. But in most cases, to ensure reliable fuses, we recommend that the fusing current be greater than 2.5 times the rated current. In addition, the fusing time is very important, and a judgment must also be made based on the manufacturer's fusing characteristics.

Calculation Method for Melt Current of Fuse Fuses
The current of a fuse includes two aspects, one is the rated current of the fuse tube, and the other is the rated current of the melt, which cannot be confused.
The Installation Precautions for Current Fuses
The installation of current fuses is crucial for ensuring the safety and proper functioning of electrical circuits. Here are some important installation precautions to keep in mind.
Precautions for Selecting Chip Fuses
With the development of highly integrated electronic products such as digital cameras, laptops, and smartphones, and urgent need for factories to adopt full automation to reduce high labor costs in the market environment. Chip fuses are widely used in overcurrent protection applications, but due to differences in technology, they have different advantages compared to plug-in self-recovery fuses. At the same time, chip fuses also have some of their own weaknesses.

What is the importance of fuses in charging pile safety and reliability?
As a safety mechanism, fuses in charging pile help prevent potential damage to the internal components of the charging station, ensuring safe and reliable charging operations. It is very important to choose an appropriate fuse for a charging pile. Factors such as rated voltage, rated current, breaking capacity and compliance with relevant safety standards should be considered.

Temperature Characteristics of Current Fuses
Current fuses exhibit specific temperature characteristics that play a crucial role in their performance and reliability. The behavior of a current fuse in response to temperature changes is determined by several factors.
Explanation of Parameters in the PPTC Specification for Self Healing Fuses
This is very simple. As long as you know the meaning represented by the parameters in the specification book, you can clearly and quickly view the PTC specification book for self recovery fuses.
Professional Knowledge of Self-healing Fuses
The operating principle of a self-healing fuse is a dynamic balance of energy. The current flowing through the self-healing fuse generates a certain amount of heat due to the thermal effect of the current (self-healing fuses all have resistance values), and the generated heat is completely or partially dissipated into the environment. The heat that is not dissipated will increase the temperature of the self-healing fuse components. The temperature during normal operation is relatively low, and the heat generated and dissipated reaches a balance.
Selection of Current Fuses in Automotive Circuits
In automotive circuits, the selection of current fuses is of great significance for ensuring the safe operation of the vehicle. There are several key factors to consider when choosing a current fuse for an automotive circuit.

Encapsulation Forms of Current Fuses
The encapsulation of current fuses is an important aspect that affects their performance, durability, and safety.
Essential Knowledge for Selecting Automotive Fuses
When a certain overload current passes through, the heat generated is radiated to the surrounding environment through the melt and shell, and the heat dissipated through convection, conduction, and other means gradually reaches a balance with the heat generated. If the generated heat is greater than the dissipated heat, the melt temperature can increase； When the temperature reaches or exceeds the melting point of the melt, the melt melts, fuses, and cuts off the current, playing a role in safety protection of the circuit.
Self Recovery Performance and Working Process of Self Recovery Fuses
Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self-recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications.
