Introduction to KTK-20 Application Field and Working Principle

The KTK-20 is a specialized type of fuse developed for applications in the electrical fields. This fuse has been designed for use in equipment with medium to high voltage ratings, and it is an essential component for protecting electrical systems from damage caused by overcurrents and short circuits. In addition, the KTK-20 can provide additional protection against voltage surges and overvoltages. As such, it is an important component in any electrical installation, as it helps to reduce the potential for costly damage or even loss of life due to hazardous conditions.

Overview of the KTK-20

The KTK-20 is an international standard fuse designed and developed to meet the needs of medium and high voltage rated electrical equipment. It is a single-element fuse that can be set to a wide range of current ratings. These fuses are available in two frame sizes, the smaller KTK-20A, and the larger KTK-20B. Both of these are rated for use up to 20kA, with the large frame being capable of higher current ratings. The KTK-20 is available with either a standard ferrule or an integrated terminal block.

Operation of the KTK-20

The primary purpose of the KTK-20 is to provide overcurrent protection. When an overcurrent is detected, the fuse will blow, thus isolating the electrical equipment from the source of the overload. This process is known as "fusion," and it involves the fuse wire melting, effectively opening the circuit and preventing any further current flow. The fuse is designed to quickly react to overloads, meaning that the likelihood of any damage to the equipment is greatly reduced.

Other Characteristics of the KTK-20

In addition to its primary role as an overcurrent protection device, the KTK-20 also offers additional characteristics that make it a great choice for use in electrical systems. It is designed to be able to operate in high ambient temperatures and in high vibration environments. This makes it suitable for use in a range of different scenarios, from industrial and commercial installations to hazardous areas such as oil and gas rigs. In addition, it is also designed to be able to withstand the effects of voltage surge and overvoltage, further protecting the system from any electrical damage.

Conclusion

The KTK-20 is a powerful and reliable single-element fuse designed for use in medium and high voltage rated electrical systems. Its primary purpose is to provide protection from overcurrents and short circuits, but it also offers additional protection from voltage surge and overvoltage. It is designed to be able to operate in high ambient temperatures and in high vibration environments, making it suitable for use in a wide variety of different applications. As such, the KTK-20 is an essential component in any electrical installation, providing peace of mind that the system is adequately protected against damage from possible overcurrents.
