KLDR6.25T Application Field and Working Principle

KLDR6.25T is a special type of electrical fuse designed for applications requiring high breaking capacity and arc-quenching performance. Its major application fields are in domestic and foreign power grids, power supply systems, communication systems, distribution systems, and control systems.

KLDR6.25T fuses are mainly composed of fuse body, fuse insert, fuse contact pieces and insulating parts. The main working principle is that when the current through the fuse reach the specified value, the fuse filament will heat and melt due to Joule Effect. The molten metal vapor would expand and increase the pressure to expel the electric energy outside of the fuse, thus the electric arc extinguished and the over-currents flow interrupted, then the fuse is disconnected and protect devices from any electric damages.

The KLDR6.25T fuses utilize an advanced non-linear form of current-limiting characteristics to safely protect electrical equipment from any damages from under-current and over-currents. This advanced feature, together with a UL approved design, makes the KLDR6.25T fuses an ideal choice for over-heating and over-current protection.

In terms of performance and stability, KLDR6.25T fuses can maintain their excellent performance levels over a full temperature range of 0-50℃. And the aging will not influence the performance of the fuse. The current limiting ratio of KLDR6.25T fuse is less than 6.3, which is satisfactory enough in any applications.

When installing the KLDR6.25T fuses, special attention should be paid to select the fuse with proper current rating, circuit design and materials to ensure the safe and reliable performance. The use of shunt-type connections, such as increasing the lead-length of the connection, can provide effective protection from process related transients. This will help the KLDR6.25T fuse protect the circuits more effectively.

In conclusion, the KLDR6.25T fuse is an innovative design that offers great material compatibility, easy installation, and superior performance compared to standard, conventional fuses. Its application fields are mainly in power grids, power supply systems, communication systems, distribution systems, and control systems, providing effective protection against over-heating and over-currents. For the safety concern, the proper selection, installation and maintenance of the fuse should be ensured.
