KLDR1.12T

KLDR 1.12T is a specialty fuse designed for small and medium-sized power systems that require large fault protection. The fuse comes in a range of sizes from 1/2 to 4 amp and has a 125% rating for short-circuit protection. In addition, the fuse has a 10kA rating which makes it suitable for protection of AC motors, transformers, and other high-current devices.

The KLDR 1.12T is a time-delay fuse, meaning that it will allow for a limited amount of current to flow for a short period of time before tripping. This is useful for protection of power systems since it will allow for some protection from lightning strikes and other momentary events.

When it comes to application fields, the KLDR 1.12T is most often used in medium- to high-voltage applications that require protection from overcurrents and short circuits. This includes AC motors, transformers, generators, and other power-related components. It can also be used in applications where there are large fault currents, such as electric arc furnaces and electric motors.

The working principle of the KLDR 1.12T is based on the eddy-current principle. This means that when an alternating-current flows through a wire, it induces eddy currents in any nearby conductive material. These eddy currents create their own magnetic field which interacts with the original alternating current. This interaction creates a resistance to the flow of current, causing the current to decrease.

When an overcurrent is detected, the KLDR 1.12T’s magnetic core draws more eddy currents. This creates a larger resistance force which causes the current to decrease even more. If the current exceeds the fuse’s rating, the fuse trips and interrupts the flow.

The KLDR 1.12T is a reliable and effective way to protect power systems from large fault currents. It is designed to detect and interrupt current flow within a short amount of time, allowing for maximum protection. The fuse is also easy to install and replace, making it a reliable option for both industrial and commercial power systems.
