Fuses play an important role in the electrical system, protecting the system from over-voltage, over-load and short circuit conditions. 0677.800MXE is one of the leading products of fuse industry, and it has become increasingly popular. This article will provide an overview of 0677.800MXE\'s application fields and working principle.

Being used in high-voltage circuit, the 0677.800MXE is mainly responsible for protecting the entire system from damages caused by over-voltage, over-load and short circuit conditions. It uses metal strip as its conducting component, and works as a protective device to cut off the electric current when the applied power increases above its rated value. It also has the feature of low contact resistance, which can support long-term stable operation.

In addition, the 0677.800MXE can also be used for circuit control purposes, particularly in those circuits that require low to moderate current. However, it has to be noted that the 0677.800MXE is not suitable for circuits that are expected to carry heavy current, such as household appliances and motor circuits. For those circulation, larger capacitive type fuses, such as 0685.50KXO should be chosen instead.

The 0677.800MXE has a thermal-overheat sensing mechanism, which can trip the control device once the temperature rises above a certain temperature. It works by means of a bimetallic strip, which can be expanded or contracted based on the temperature. This bimetallic strip is attached to the circuit breaker, which put the whole system into an open loop when the temperature exceeds the prescribed limit. At the same time, the fuse will also melt down and interrupt the current flow, making sure that the system is protected from overload.

In conclusion, the 0677.800MXE is a kind of fuse suited for medium voltage applications. It has the advantages of low contact resistance and thermal-overheat sensing mechanism, ensuring that the electrical system is well-protected from over-voltage, over-load and short circuit conditions. It is important to note that the 0677.800MXE is not suitable forcircuits that carry heavy current and capacitive type fuses should be used instead.
