047601.6MR Circuit Protection

Fuses play an important role in the production and operation of industrial equipment. The 047601.6MR is a type of fuse specially developed for the locomotive auxiliary fan of diesel locomotives. Its application fields and working principles will be further elaborated in this article.

Application Field

047601.6MR is used for the overcurrent protection of the DC auxiliary fan of diesel locomotives. Auxiliary fan is an indispensable part in locomotives, in order to ensure the normal working of the locomotive, the auxiliary fan must run continuously during the running of the locomotive. Otherwise, the temperature of the locomotive will gradually become higher, and the safety of the locomotive will be jeopardized. Therefore, it is necessary to install the 047601.6MR fuse.

Working Principle

When the overcurrent flows through the 047601.6MR fuse, its fuse element is heated due to Joule effect and its temperature rises gradually. When the temperature reaches its melting point, the melted alloy melts quickly and interrupts the current. This closes the circuit and isolates the current, thus prohibiting the further flowing of overcurrent. The 047601.6MR fuse is composed of two kinds of alloy materials, namely copper and tin, which have low melting points and can be easily melted at a temperature below 400 ℃. This can prevent the circuit from being damaged due to excessive current, thus ensuring the running safety of the locomotives.

Advantages

The 047601.6MR fuse has several advantages over other fuses. Firstly, it has a small size and is light in weight, which is convenient for installation and transportation. Secondly, it has a fast response speed and can quickly / accurately interrupt the current in case of overcurrent, thus eliminating the potential safety hazard. Thirdly, it is not easy to be damaged due to overcurrent. Even if the current exceeds its rated current, the fuse element will quickly heat up and isolate it without causing other damaging to the circuit. In summary, the 047601.6MR is an ideal type of fuse for locomotive auxiliary fan overcurrent protection.

Conclusion

In conclusion, 047601.6MR is an ideal type of fuse for the overcurrent protection of the DC auxiliary fan of diesel locomotives. It has a small size, light weight, fast response speed and is not easy to be damaged. It is an effective way to protect the locomotives and ensure their normal operation.
