5HFP 800 Fuses

5HFP 800 is a kind of fuse product developed and produced by a well-known Chinese manufacturer, which is widely used in various applications, with simple use and reliable performance. It is a fuses with strong protection, being able to bear larger current and being low cost and easy to install.

1.Applications of 5HFP 800

5HFP 800 are mainly used in the electrical equipment such as circuit breakers, AC motors, AC power supplies, and UPS systems. Because of its high safety level, it can be applied to the prevention of overcurrent in many areas, such as industrial equipment, automotive equipment, communication and medical equipment.

2.Working Principle of 5HFP 800

The working principle of 5HFP 800 is based on the melting of fuse element. When the current passes through the fuse element, resistive heat is produced due to the resistance. The heat will continue to accumulate until a certain temperature, and the fuse element will melt, so that the current can\'t be transmitted, and the power of the circuit is cut off, and the over-current is effectively prevented.

3.Advantages of 5HFP 800

The biggest advantage of 5HFP 800 is its high breaking capacity. Compared with ordinary fuses, its breaking capacity is much larger, which is an important factor that can guarantee its safe performance in the application. Moreover, its cost is relatively low, and its installation and maintenance are very simple.

4.Disadvantages of 5HFP 800

The main disadvantage of 5HFP 800 is its low repeatability. Once the fuse element is blown off, it can not restore its original working state, and it needs to be replaced with a new one. Besides, the working time of this fuse is quite long, which is not very useful for fast protection.

5.Conclusion

Although 5HFP 800 has some disadvantages, its advantages outweigh its disadvantages. Its large breaking capacity, low cost, simple installation and use, make it very suitable for extensive applications in different industries. Therefore, it has been widely used and is an ideal choice for protecting the circuit from overcurrent.
