KLKR.750TS application field and working principle

KLKR.750TS is a high-performance fuse produced by the Shanghai Kexun Wind Research and Development Co., Ltd. It belongs to electrical specialty fuses. This product has a variety of application fields and its working principle is mainly based on thermal overload protection.

Application field

KLKR.750TS is widely used as an electrical overload protection device. It can be used in the power system of family, civilian buildings and public facilities, as well as the secondary loop of electrical equipment circuit. With a current rating of 750A, it is mainly used in devices like circuit breaker, air switch, circuit distribution fuse cutout, motor, generator, transformer and similar devices. Its breaking capacity can reach up 300kA.

Working principle

Modern fuses become smaller and lighter than in the past due to the use of composite materials and three-dimensional circuit printing. However, the working principle of its thermal overload protection remains unchanged. This product is composed of a conductor surrounded by protective insulation materials. When current flows through the conductor, it will generate heat through Joule effect. If the current is too big or continues too long, the temperature of the conductor will keep increasing until it reaches the melting point of the conductor and the conductor deforms and breaks. In this way, the circuit will no longer have any electricity, which will realize the purpose of overload protection.

Advantages

KLKR.750TS has a series of advantages. First, it is designed according to IEC standards, thus ensuring its reliability and stability. Second, it can work in a wide range of temperatures, from -25°C to 70°C, and can even resist the sudden rise of temperature up to 120°C. Third, the fuse has a wide range of application fields. Moreover, its melting ability is good and its breaking capacity can reach up to 300kA.

Conclusion

KLKR.750TS is a high-performance fuse developed by the Shanghai Kexun Wind Research and Development Co., Ltd. It belongs to electrical specialty fuses. With a current rating of 750A, it is mainly used in the power system of family, civilian buildings and public facilities. Its working principle is mainly based on thermal overload protection. Moreover, with a wide range of application fields and a series of advantages, it will be an ideal choice for power system overload protection.
