Electrical Specialty Fuses have been around for more than one hundred years and are still widely used today. The 004225013 fuse is an example of a specialty fuse that forms an essential part of many electrical circuits and systems. Understanding the characteristics of this fuse, how it works, and its applications in various fields is important for anyone involved with electrical engineering.

Fuse Characteristics and Construction

This specialty fuse is made of two metals that yield under specific conditions, forming an electrical circuit. Under normal circumstances, current flows freely from one point to another through the fuse. When current overloads pass through the fuse, the two metals will melt together, forming an electrical resistance and limiting the flow of current until normal levels are restored. The length of this fuse is 25mm, the outer diameter is 4.2mm, and the inner diameter is 2.5mm. It can be used for currents of up to 3A.

The Fuse Working Principle

The 004225013 fuse has a built-in thermal-magnetic switch. This switch is designed to detect changes in both the temperature of the fuse and the intensity of the magnetic field that surrounds it. When the temperature and the magnetic field levels exceed pre-determined thresholds, the switch turns on, resulting in an electrical circuit that limits the flow of current. This in turn reduces the risk of an electrical device or appliance getting damaged due to excess current.

Application Fields

This fuse is primarily used in low-voltage applications, from 0.5V to 250V. It is used in electronics, appliances, and circuit boards. It is an essential part of the electrical safety systems in televisions, VCRs, laptops, and automobiles. In addition, it is commonly used in electronic control systems, instrument systems, and multi-level systems in production lines. Due to its reliable performance and high-quality materials, it is also popular in high-precision measurement and control systems.

Conclusion

The 004225013 fuse is a versatile yet reliable electrical component that is widely used in both low and high-voltage applications. Its robust construction makes it ideal for specialized electrical systems that require precision in current flow measurement. Whether used in small electronic devices or large production lines, this fuse is an essential part of any electrical system.
