Fuses are widely used in the field of electrical safety protection because of their characteristics such as high current carrying capacity, fast response time and easy operation. MDA-8-R is a kind of specially used fuse. It is used in the field of electrical safety equipment, and it has the advantages of wide range of voltage and current, fast response time, high reliability and long life time.

The application field of MDA-8-R mainly includes electric motors, electric loconotives, electric ships, alternating current Control Cabinet, stabilizer, transformer, chemical production, power grid and other fields. In addition, it is also applied for overload and short circuit protection in the field of instrumentation and automation.

The working principle of MDA-8-R is to cut off the circuit when the current exceeds the specified limit, thus protecting electronic Technology Appliances, electrical circuits, etc. from fire or other dangers. When a current passes through the MDA-8-R, a small portion of the current is used to heat up the wire, and when the current exceeds a certain value, the wire will be heated to a high temperature to form a melting point. At this time, the whole circuit is disconnected, and the current is stopped.

The working principle of MDA-8-R is based on the electro-thermal effect. The working judgement relies on the thermal effect of the wire heating caused by the current, and the breaking of the circuit is caused by the melting of the wire. This method is suitable for short-term current overload or short-circuit protection.

The excellent performance of MDA-8-R is mainly reflected in the following aspects. First of all, its voltage range is wide, which is suitable for different rated voltage circuits. Secondly, its response time is very fast, which can protect electronic equipment and circuits from serious damage in time. Thirdly, its anti-vibration capability is strong, which can ensures that the product can work normally in harsh environments. Finally, its extreme temperature resistance and high corrosion resistance make it very robust and long lifetime.

In conclusion, MDA-8-R has wide applications field and the working principle is based on the electro-thermal effect. It has excellent performance, such as fast response time, wide voltage range, strong anti-vibration capability, high corrosion resistance and strong extreme temperature resistance, making it suitable for overload and short circuit protection in the fields of instrumentation and automation.
