2JS 5 application field and working principle

2JS 5 is a kind of fuse with special characteristics. Its application field and working principle are summarized as follows:

1.Application Field of 2JS 5 Fuse

2JS 5 is a kind of surge current-resistant, over-current-proof, and short-circuit-proof fuse. It is widely used in mechanical and electrical equipment, industrial automation, communication power supply, low voltage and high frequency electrical system, etc.

2.Working Principle of 2JS 5 Fuse

The fuse element is the main part of the fuse, and its function is to reduce the current when the current exceeds the rated current. The fuse contains two metal wires that are tightly connected. When the current is greater than the rated current, the heat generated in the two metal wires by the current causes them to melt, lose their conductivity, and stop the current.

3.Advantages and Disadvantages of 2JS 5 Fuse

The Advantages: 2JS 5 is relatively cheap and widely used, and is very convenient to replace, not only can avoid the damage caused by short circuit over current, but also can detect some problems of the electrical circuit.

The Disadvantages: It does not have an adjustable function and it can\'t accurately detect some small fault currents. Therefore, it can not effectively protect the circuit from damage.

4.Usage of 2JS 5 Fuse

2JS 5 fuses need to be replaced in time when it is necessary to replace them. The required order of use is to connect the ground line first, and then the power line, so as to ensure the safety of personnel and equipment.

5. Conclusion

In conclusion, 2JS 5 is a kind of surge current-resistant, over-current-proof, and short-circuit-proof fuse with great application value. Its working principle is convenient and simple, and it has strong anti-interference ability. However, it is still necessary to replace it in time, and its use process should pay attention to the order.
