BK/GFA-1/200 application field and working principle

Fuses are no stranger to the public; they can be seen everywhere in our lives. As a product of ultra-fast, current limiting protection, fuses play an important role in our electrical system, and are widely used in workshop, light industry, technology industry, electronic industry and so on. Fuses are divided into mechanical type, thermal type, semiconductor type, and magnetic type. Among them, BK/GFA-1/200 belongs to thermal type.

What is BK/GFA-1/200?

BK/GFA-1/200 is a kind of special type of thermal fuses. It is mainly used as a thermal protector under the double insulation condition of electrical equipment. It has a high temperature response and low thermal stability coefficient, which means it triggers quickly when the temperature reach up to the pre-set level. BK/GFA-1/200 has been classified as Class A according to UL 248-14 standard, and its rated voltage is 125V. The maximum operating temperature of BK/GFA-1/200 is 200°C, and its maximum operating current is 16A. This kind of fuse has many advantages, such as small size, high overload capacity, no arc and low temperature coefficient.

Application Field

Thanks to its excellent performance and notable features, BK/GFA-1/200 is widely used in various kinds of electrical equipment, such as copiers, laser printers, electric stoves, hair dryers, electronic coffee makers, water heaters, refrigerators, burgers shapers and so on. It is a unique tool which can respond to the temperature changes in the circuit quickly and effectively, and all the operations can be realized quickly and accurately.

Working Principle

BK/GFA-1/200 utilizes embedded thermal element to protect the circuit from damage due to over-current or over-temperature. When the current passes through the fuse, the temperature of the embedded thermal element increases gradually and it will open when the temperature of it reaches to the pre-set level. The current rating of BK/GFA-1/200 is adjustable by special process, and the reset temperature can also be adjusted according to the voltage of the electrical equipment.

Advantages

BK/GFA-1/200 fuse offers a lot of advantages over other types of fuses. First, it is of small size and lightweight, which makes it suitable for installation in small parts. Second, BK/GFA-1/200 has a high overload capacity, which can protect the circuit from over-current up to 16A. Third, BK/GFA-1/200 has no arc when it is working and it has a low temperature coefficient. Last but not least, the reset temperature of this kind of fuse can be adjusted according to the voltage of the electrical equipment.

Conclusion

To sum up, BK/GFA-1/200 is a kind of thermal protection fuse which can protect electrical equipment from over-current and over-temperature due to its excellent performance. It has a range of advantages, such as small size, high overload capacity, no arc and low temperature coefficient. Nowadays, BK/GFA-1/200 is widely used in various kinds of electrical equiopment, such as electric stoves, hair dryers, copiers and so on.
