Fuses

3412.0117.22 Application Field and Working Principle

Fuses are widely used as control and protection devices in electrical circuits. They are an important part of our electric appliances, such as television, air conditioner, refrigerator, microwave oven, etc. They are responsible for preventing overloaded circuits before overcurrent occurs and melting the fuse element when the current is too large to protect the circuits and personnel.

Features of 3412.0117.22 Series Fuse

The 3412.0117.22 series protective fuse belongs to the American National Standard UL248 & UL498 seris, and its protective feature is Overload and Short Circuit. According to the American UL standard, 3412.0117.22 - 10A fuse is a commonly used fast-break glass tube fuse, with the characteristics of small size, light weight, good insulation and strong overload protection.

Applications of 3412.0117.22 Series Fuse

The 3412.0117.22 series fast-break glass tube fuses are mainly used in various household appliances, such as air conditioners, refrigerators, televisions, microwave ovens, washing machines, vcd players, stereo amplifiers, and a variety of office and industrial automation equipment that requires overload and short circuit protection.

Working Principle of 3412.0117.22 Series Fuse

The structure of 3412.0117.22 series fuses is simple. It is composed of a fuse plug and a fuse element. When the over-current flows through the fuse element, the element generates heat and is usually made of metal materials with low melting point. The increase of temperature accelerates the melting speed of the fuse element, and the over-current will be broken off immediately, so as to achieve the effect of over-current protection. In addition, its basic working principle is as follows: when the current passing through the fuse element is normal, the heat generated by the current is small, and then dissipates quickly, so the heat does not accumulate and has no effect on the normal working of the circuit.

Conclusion

In conclusion, the 3412.0117.22 series fuses are mainly used in various household appliances, such as air conditioners, refrigerators, televisions and microwave ovens, as a protection device to prevent over-current and short circuits. Its working principle is mainly based on melting the fuse element when the current exceeds the specified value, thus playing the role of protecting the circuit and personnel.
