RUEF800K-2

PTC resettable fuses are an important type of fuses used in applications across many industries. They are widely used to protect circuits against short circuits, over-currents, and over-heating. The RUEF800K-2 is a particular type of PTC resettable fuse that is designed to match specific requirements, applications, and working principles.

In terms of its application field, the RUEF800K-2 is primarily designed for automotive systems, as it can offer thermal protection in situations where high-current protection is needed. It can also be used in applications where manually reset fuse protection is required.

The working principle of the RUEF800K-2 is based on the effect of self-resistance heating. When current flows through the fuse, the internal resistance increases, which in turn creates a temperature rise. The temperature rise increases the resistance further, which eventually causes the fuse to trip.

The RUEF800K-2 can handle currents up to 800A, and the temperature of the fuse can reach up to 300°C. This allows the fuse to offer effective thermal protection in high-current applications. The fuse is also equipped with a so-called PTCI timer, which allows the user to set the time it takes for the fuse to trip. This time can be set between 0.5ms and 1.5ms.

Apart from offering effective thermal protection, the RUEF800K-2 also comes with a number of other features. It comes with a clear, easy-to-read indication of the operating status, and it has a low resistance design, which ensures that the voltage drop is kept to a minimum. The fuse is also designed to be vibration-resistant, and it can be mounted horizontally or vertically to meet different installation requirements.

In conclusion, the RUEF800K-2 is a highly effective PTC resettable fuse designed for use in automotive systems and other applications where manually reset fuse protection is required. It offers thermal protection in high-current applications, and its clear indication of the operating state, low resistance design, and vibration-resistant design make it a reliable and user-friendly choice for many applications.
