3402.0018.11 application field and working principle

3402.0018.11 fuses are mostly used in metallic vacuum interrupter systems for high voltage electrical apparatus. This type of fuse is designed with a high breaking capacity, meaning they are suitable for systems with high levels of energy dissipation. In addition, these fuses are non-ageing, so they are well-suited to applications where the power system needs continuous electrical protection.

The 3402.0018.11 fuse has an arc-extinguishing chamber, in which the arc is broken when the fuse fuse melts. The operating principle of this fuse is based on the Ohm’s law– as current through the fuse increases, the fuse wire heats up and eventually reaches the melting point. Once the fuse wire melts, an arc is created between the fuse ends, which is then extinguished by the arc-extinguishing chamber.

When in operation, the fuse continually monitors the current, ensuring that it is within safe operational limits. Should the current exceed the specified limit or trip level, the fuse will rapidly open, eliminating high currents from the system. This is known as a tripping action, which helps protect the electrical system from over-current and resulting damage.

The 3402.0018.11 fuse is designed to be extremely reliable. This is because the fuse wire used is made of ultra-high purity material, which is both conductive and robust. Additionally, the fuse is contained within a special housing, which provides a barrier to UV light and moisture, both of which can damage the fuse wire.

These fuses come in several designs, with the most popular being the surface mount design and the flush mount design. The surface mount design is suitable for applications where the fuse must be readily accessible, while the flush mount design is best for spaces with limited space. Additionally, these fuses are available in various current ratings, making them suitable for different applications.

In summary, the 3402.0018.11 is a robust, reliable and high breaking capacity fuse. Its design offers superior protection for metallic vacuum interrupter systems, allowing for continuous operation. In addition, it is available in various designs and current ratings, making it a great choice for many applications.
