Electrical, Specialty Fuses: 7.2WKMHO2 2X355 Application Field and Working Principle

Introduction

Fuses are an important component in any electrical application – they are what help to protect the system from damage. The 7.2WKMHO2 2X355 is a specialty type of fuse that has a wide variety of applications. This article examines the application field and working principle of this particular specialty fuse.

Application Field

The 7.2WKMHO2 2X355 fuse is a specialty fuse that is mainly used for medium voltage applications. This type of fuse offers a high degree of protection and can be used for applications such as motor control, transformers, and pump motor protection. It is also commonly used in power distribution systems such as factories, warehouses, and commercial buildings.The 7.2WKMHO2 2X355 fuse is designed to protect a variety of circuit types, including high- and low-voltage circuits, AC or DC systems, single- and three-phase circuits, and more. It is also designed to be installed in environments that may be exposed to moisture, vibrations, and other potentially damaging conditions.

Working Principle

The 7.2WKMHO2 2X355 fuse has a simple working principle. When the current that is flowing through the fuse exceeds the maximum fuse rating, the fuse will “blow,” meaning that it will disconnect the circuit. This will protect the electrical components from damage due to overloading or short-circuiting.The 7.2WKMHO2 2X355 fuse is equipped with a current breaking capacity of 7.2 kA rms at a rated working voltage of 355 V AC. It also has a current limiting capacity of 4A, allowing it to react quickly when an overload or short-circuit occurs.The 7.2WKMHO2 2X355 fuse is also designed to withstand a variety of conditions, including strong mechanical vibration and extreme temperatures. This is due to the ultra-hard alumina ceramic body which is used as its primary material.

Conclusion

The 7.2WKMHO2 2X355 fuse is a versatile and reliable specialty fuse for protecting a variety of electrical circuits. It has an impressively high current breaking and limiting capacity, as well as a number of exceptional features which make it suitable for use in a wide range of applications. With its simple working principle, the 7.2WKMHO2 2X355 fuse is a great choice for medium voltage applications.
