What are the Types of Glass Tube Fuses
What are the types of glass tube fuses?
1. According to the protection form: overcurrent protection and overheating protection. The fuse used for overcurrent protection is commonly referred to as a fuse (also known as a current-limiting fuse). Fuses used for overheating protection are generally referred to as "temperature fuses". Temperature fuses are also divided into low melting point alloy type, temperature sensing contact type, and memory alloy type, etc. Temperature fuses are used to protect against excessive temperature changes in heating appliances or Yi Ge heating appliances, and their working principle is different from "current limiting fuses" The melting of temperature fuse is independent of the operating current of the circuit.
2. According to the scope of use: power fuse, machine tool fuse, electrical instrument fuse (electronic fuse), automotive fuse.
3. According to the rated voltage level: high-voltage fuse, low-positive fuse, and safety voltage fuse.
4. According to breaking capacity: high breaking capacity fuse, low breaking capacity fuse.
5. According to shape: flat head tubular fuse (also divided into internal and external welding fuses), pointed head tubular fuse, blade fuse, spiral fuse, plug-in fuse, flat fuse, tamper fuse, and patch fuse.
6. By material: glass fuse, ceramic fuse.
7. According to the melting speed: ultra slow fuse (-: usually represented by TT), slow fuse (- usually represented by T), medium fuse (usually represented by M), fast fuse (usually represented by F), and ultra fast fuse (-~usually represented by FF).

Precautions for Using Fuses
The fuse is connected in series with the circuit, installed vertically, and installed on each phase line； Fuses are not allowed to be installed on the neutral line of a two phase three wire or three-phase four wire circuit.The power input terminal of the spiral fuse should be connected to the center point of the base, and the output wire should be connected to the threaded shell； This insurance is used in places with vibrations.
Encapsulation Forms of Current Fuses
The encapsulation of current fuses is an important aspect that affects their performance, durability, and safety.
The Role of Current Fuses in Smart Meters
Current fuses play a vital role in smart meters. Firstly, they provide protection against overcurrent events. Smart meters are used to measure and manage electricity consumption accurately. However, electrical circuits can sometimes experience sudden surges in current due to various reasons such as power outages and subsequent restoration, short circuits in the electrical grid, or the malfunction of connected electrical appliances.

How to Choose a Patch Fuse?
Chip fuses are mainly used in electronic products such as digital cameras, laptops, and mobile phones. From traditional glass tube fuses to micro fuses and chip fuses, the focus of their selection is slightly different due to differences in product technology.
The Selection of Miniature Fuses
Miniature fuses are primarily used in digital cameras, laptops, mobile phones, and other electronic products. From traditional glass tube fuses to miniature fuses, the selection focus varies slightly due to differences in product technology. The selection of miniature fuses involves the following elements.
What is the Reason Why the Fuse Keeps Burning Out?
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.
Power System Fuses Play A Fundamental Role in Maintaining the Integrity and Safety of These Systems
Power systems are the backbone of modern society, supplying electricity to homes, businesses, and industries. Power system fuses play a fundamental role in maintaining the integrity and safety of these systems.
The Types of Fuses
According to different usage scenarios and characteristics, fuses can be divided into the following types:Glass tube fuse is the most common type of fuse, usually composed of a glass tube and two end joints, with a metal wire inside. When the current exceeds the rated value, the metal wire will melt and cut off the circuit. This type of fuse is usually suitable for low voltage, low current circuits.

Self Recovery Fuse on Mobile Power PCB Board
The mobile power supply consists of overcurrent protection devices, batteries, and control charging and discharging circuits. The previous charging and discharging circuits used ICs for overcurrent protection, which were complex, had high failure rates, and high costs. Some users returned or repaired the circuit, and the manufacturer was fined and claimed compensation, which caused great trouble for manufacturers and designers. The above problems must be solved in order to promote their application.
The Development History of Micro Fuses
From a long-term perspective, the development process of micro fuses is mainly a new variety derived to meet market demand. Fuses protect the circuit by fusing themselves with the Joule heat of the current flowing through the body of a fusible metal, thereby cutting off the circuit.
Determine if the Fuse is Burning (Fuse)？
If the fuse can be removed from the circuit, it can be a visual fuse to determine whether it has burned out； The simplest method to determine whether a fuse is a continuity test is to blow other materials. Quickly test with a multimeter to determine if it is working properly, by hearing a beep and touching the wires together, or seeing a 0 ohm reading. After confirming that the circuit power is turned off, place the leads at both ends of the fuse.
How to Choose a Fuse
Firstly, what is a fuse? Fuses are made of low melting point alloys, commonly used as alloys of lead and tin (75% lead and 25% tin), as well as alloys of lead, tin, and lead-antimony. Generally, fuses are installed in fuse boxes (fuses) or knife switches and connected in series in the circuit. When the current in the circuit is too high, due to the thermal effect of the current, the fuse first melts and is burned out, causing the circuit to automatically cut off, thereby protecting the safety of the power supply and electrical equipment.
