0278002.V Fuses Application Field and Working Principle

Fuses are one of the most primary and important parts of all kinds of electrical devices. As the electrical industry is undergoing rapid development, the electrical fuses are also being improved constantly, and a variety of models of fuses have been produced. One of the frequently used models is 0278002.V, and this article will tell you more about its features, application field and working principle.

Features

0278002.V is a type of Universal Fuse. It has an excellent temperature-resistance, overload-resistance and internal circuit protection capability. It is mainly used for AC power circuits or DC power circuits, offering fast disconnection protection. The fuse has a small size and convenient installation, so it can save a lot of space and reduce the installation time. In addition, it has a long life of up to 5000 cycles, ensuring smooth and reliable operation of your electrical devices all the time.

Application Field

The 0278002.V fuses can be applied to a range of places. It is widely used in the circuits of office automation equipment, communication equipment, instrumentation, industrial electronics, navigation and aviation. In addition, it is often used as a transformer or motor protection device.

Working Principle

The working principle of the 0278002.V fuse is quite simple. Basically, it consists of two metal strips which are arranged in series. When the current flows through the fuse, a temperature rise occurs and the heat generated by the current will cause the fuse strip to expand, leading to an increase of the gap between two strips. When the current is too high, the fuse strip will be blown out, and the breaking of the electric circuits to ensure the circuit\'s safety.

Conclusion

To sum up, 0278002.V fuse is one of the most frequently used models in the electrical industry. It has many features such as temperature-resistance, overload-resistance, fast disconnection protection, small size and convenient installation. In addition, it can be widely applied to different places and its working principle is quite simple.
