KTK-R-10BC

Introduction

The KTK-R-10BC is an electrical specialty fuse designed to protect low voltage DC and AC circuits. It is a fast acting, current limiting, dual blade fuse intended to protect against short circuits and overloads. The fuse can also be used to protect devices in the circuit from other abnormal electrical conditions. The KTK-R-10BC is current-limiting and can help protect sensitive electrical equipment from damage due to different types of electrical overloads.

Application Fields

The KTK-R-10BC is an ideal choice for a variety of electrical applications including automotive, power control boards, machine controls, circuit breaker panels, motor control panels, lighting systems, and industrial control circuits. It can also be used in uninterruptible power supplies, renewable energy equipment, and any other applications that require a reliable over-current protection.

Due to its small size and reliable current-limiting capability, the KTK-R-10BC is an ideal choice for low-voltage AC or DC circuits in tight spaces. It is UL E76960-listed and can help to reduce the risk of downtime due to power overloads. Additionally, the KTK-R-10BC features an anti-resonance construction which helps to protect against surges.

Working Principle

The KTK-R-10BC is a specially designed, current-limiting fuse. Its working principle is based on a two-stage current limitation process. In the first stage, the fuse edges start to melt when the current level exceeds the fuse rating. As the current level increases, the melting of the edges increases. This limits the current reaching the rest of the fuse.

In the second stage, the melting edges act as a resistive element, further limiting the current and protecting the load. Depending on the current levels, it takes around 0.5 seconds to reach the melting edges, and 2.5 seconds to reach the second stage of current limitation and protect the load. The fuse is quickly able to interrupt current levels up to 600A and can operate up to 75V in DC applications.

Conclusion

The KTK-R-10BC is a fast-acting, current-limiting, dual blade fuse designed to protect AC or DC circuits from different overload events. Its small size and reliable current-limiting capability make it an ideal choice for a variety of electrical applications such as automotive, power control boards, machine controls, circuit breaker panels, motor control panels, lighting systems, and industrial control circuits. It is UL E76960-listed and can help to reduce the risk of downtime due to power overloads.
