KTK-7

1 Introduction

KTK-7 is an innovative and reliable low-voltage power fusing and protection product launched by the Fuse design team of the TKA Group. It provides comprehensive properties, efficient operation, and high-powered protection in various electrical applications such as distribution, over-current, surge, arc and fault protection.

2 Application Field of KTK-7

The KTK-7 is an electrical fuse used for protection from over-current, surge, arc and fault in distribution system, it is ideal for range of applications, such as industrial and commercial buildings, schools and universities, homes and offices, medical facilities, transportation systems, and remote locations. This device can also be used for lighting circuits, 115/230V control circuits, single and three phase systems, and communications systems.

The KTK-7 can be used for both distribution and protection. The maximum voltage rating is 600Vac and the maximum current rating is 600A. It can be used in either AC or DC circuits, and has been designed to prevent the wires from being overloaded. It also has both over-current and surge protection capabilities, and can be used in conjunction with other over-current protections, such as circuit breakers.

3 Working Principle of KTK-7

The KTK-7 is designed to protect circuits from over-current by using a special fuse element. It works by breaking the circuit when the current exceeds a certain amount. The fuse element is made of two parts, a high-temperature self-resetting element and a low-temperature blow element. When the current through the fuse exceeds the fuse rating, the blow element will heat up and expand, creating an opening in the fuse. This will allow the current to pass through the fuse, resetting the fuse and restoring power to the circuit. The self-resetting element will then slow down the current and reduce the temperature, preventing further damage.

The KTK-7 also protects against surges by employing a combination of surge protectors and an internal resistor. This combination works to absorb the excess energy from the surge, preventing it from reaching the rest of the circuit and causing damage. The KTK-7 also offers arc and fault protection, which protect the circuit from dangerous arcs or faults that occur as a result of loose connections, over-currents, or other problems.

4 Conclusion

In conclusion, the KTK-7 is an advanced and reliable low-voltage power fusing and protection product. It provides comprehensive properties, efficient operation, and high-powered protection in various electrical applications such as distribution, over-current, surge, arc and fault protection. The KTK-7 can be used in a variety of applications from motor control to communications systems, and offers both over-current and surge protection. Additionally, it also offers arc and fault protection, making it an ideal choice for a variety of applications.
