Introduction

FNM-12 is a type of speciality fuse specifically used in high voltage applications, including direct current (DC) and alternating current (AC). It is designed with a number of desirable features, including enhanced protection against electrical shock and sparks, alongside the ability to withstand higher temperatures. This type of fuse is usually installed on electrical systems or components to provide protection in the event of power overload or short circuit.

Application Field

FNM-12 fuses have a wide range of application in the electrical industry, with their main application being to provide overcurrent and short-circuit protection. These fuses can be used in different types of equipment, such as circuit breakers, transformers, motors, generators, etc. As they are able to withstand higher temperatures, and because of their small size, FNM-12 fuses are often used in small-scale, delicate electronic equipment. Moreover, the FNM-12 can also be utilised in industrial applications where there is a risk of short-circuit or overload, such as in industrial power systems, motor control centres, UPS systems, power distribution panels, and other related equipment. These fuses are also suitable for use in telecommunications equipment, instrumentation systems, or other systems with high levels of current or voltage.

Working Principle

FNM-12 fuses operate on the principle of melting a metal disc at a specific temperature that is set by the rating of the fuse. This is known as the “fusing temperature”. When the current flowing through the fuse exceeds its rated value, the fuse will heat up and eventually melt the disc. This interrupts the flow of current through the circuit, thus providing protection against overload and short circuit. The FNM-12 fuse is a type of thermal-magnetic fuse, which means that it is both temperature sensitive and current sensitive. This means that when the current in the system exceeds a certain pre-set limit, the fuse will heat up and melt the metal disc, and when the temperature of the circuit becomes too high, the metal disc will melt and interrupt the flow of current regardless of the current.

Conclusion

FNM-12 fuses are a reliable and secure way of providing protection to a variety of electrical systems and components against overload and short-circuit. They are commonly used in a variety of industries due to their ability to withstand high temperatures and their small size, which makes them suitable for use in small-scale electronic equipment. Finally, they operate on the principle of melting a metal disc at a specific temperature that is set by the rating of the fuse.
