FMX-20 Application Field and Working Principle

Fuses are used for the purpose of interrupting a circuit to protect it, devices and people in numerous application fields. Among them, the FMX-20 is one of the most reliable and versatile high AC (alternating current) and DC (direct current) interruption sources available today. This article will focus on the application field and working principles of the FMX-20, discussing the basics of why it is used, how it works, and what makes it unique among the many fuses on the markets.

FMX-20 Application Field

The FMX-20 is mainly used in power distribution applications, especially in medium and high voltage applications. It enables safe current interruption on transformers, motors, control circuits, and other heavy-duty applications. It is also used in lighting, air conditioning, and refrigeration systems. Moreover, FMX-20 is suitable for use in airplanes because it meets the requirements for flame resistance, current interruption, and arc extinguishment.Apart from its power distribution applications, the FMX-20 can also be used in industrial and residential applications. It is suitable for spot welding and many low-voltage high-current applications. It can be used in pumping systems, valves, compressors, and other heavy-duty machinery. Additionally, it is suitable for automotive, military, and communication systems.

Working Principle of FMX-20

Fuses are passive electrical components, meaning they are wired in a circuit to create an intentional current interruption when tripped. The FMX-20 works similarly to other fuses, but it has a few unique features. The primary component of the FMX-20 is a two or three-part case that contains a metal wire coil.The FMX-20 has a unique semi-conductor containing material that transfers current during the fuse trip, allowing for an interruption or opening of a circuit. When the current exceeds the limit of the fuse, the metal wire coil inside the case generates heat, breaking the semiconductor material in the device and creating a current arc. This helps the fuse to quickly interrupt the current and open the circuit.FMX-20 also features a unique horned shape that eliminates the risk of damages caused by external forces. This is especially helpful in high voltage applications and industrial machines, where the risk of explosion is higher than usual.The FMX-20 also differs from most fuses when it comes to the process of resetting it after being tripped. When the current flows through the FMX-20 and the wire coil reaches its melting point, the device will automatically trip and open the circuit. However, unlike other fuses, the FMX-20 does not require an external resetting system like a switch or timer, making it very easy to reset and use again.

Conclusion

The FMX-20 is a reliable and versatile high AC and DC interruption source, designed for a variety of applications. It is mainly used in power distribution and industrial and residential applications. Its unique features such as semi-conductor containing material, horned shape, and automatic resetting make it one of the preferred fuses on the markets.
