BK/KTK-R-5 Application Field and Working Principle

In this article, we will focus on the general application field and working principle of the BK/KTK-R-5 style of fuse. BK/KTK-R-5 electrical specialty fuses are a type of fuse used in multiplex control and protection circuits. These wide-ranging fuses are designed as an overcurrent protection device with a voltage rating of up to 600 volts, and its operation and performance are tailored to meet the power system needs of industrial units. Its products come in a wide range of sizes, from 0.1-13 amperes.

Application

The BK/KTK-R-5 fuse is widely used in a variety of applications, such as controlling and protecting high-current systems. This can be found in the fields of aerospace, education, instrumentation, power, railways, and more. It is especially used in series electronic circuits for protecting other electrical components, as well as in stationary or movable power supply and transmission devices.

Working Principle

BK/KTK-R-5 Fuses function by interrupting, or terminating the electrical current flow when the current reaches a certain level. This works by the fuse breaking a metal circuit in the presence of an over-current. The fuse is designed to melt due to the high temperature created by an especially large current, breaking the circuit and thus protecting the rest of the system. The metal circuit is composed of an electrothermal material that melts when the heat generated by the current exceeds the material’s maximum allowable temperature.

Furthermore, the heat generated by the current physically damages the contacts in the fuse, thereby interrupting the current and preventing the system from further damages. The fusing process time also is very fast, typically occurring within one second.

Conclusion

The BK/KTK-R-5 electrical specialty fuse is an extremely versatile and reliable over-current protection device. It is designed to interrupt the electrical circuit upon the occurrence of an over-current.

The BK/KTK-R-5 fuse is widely used in a variety of applications, ranging from aerospace to power.
