FRS-R-20 is a special type of electrical fuse that has the function of protection and interruption of fault current circuits. It is designed to protect against short circuits in circuits carrying currents up to 20A. It is used in applications such as power distribution, industrial switchgear, power transmission, and other various control equipment. FRS-R-20 also has a low interruption capacity, making it suitable for applications in the control of voltage sensitive components.

FRS-R-20 provides voltage and current protection for circuits by interrupting the current when the current carrying component meets predetermined values. This type of fuse has a high interrupting capacity and can withstand over-current of up to 20A. It is also designed with the capability to withstand short-duration surge currents of up to 40A.

The operation of this type of fuse is very simple; when the current rises to a predetermined level, an internal coil heats up. This creates an electromagnetic field which, in turn, generates a force which opens the contact of the fuse. This interrupts the electrical circuit and protects the component from potential damage. The current is interrupted in this manner since the contact of the fuse is automatically opened.

The FRS-R-20 fuse is also designed with a high temperature tolerant material. It is capable of operating in extreme temperatures, up to 200°C (392°F). This makes it suitable for use in applications involving high temperatures. The high temperature tolerant material also allows for improved safety in certain applications.

The FRS-R-20 fuse has a number of advantages over other electrical fuses; it is fast-acting, fails safely and prevents short circuits. This reduces downtime for equipment and provides maximum protection to the electrical system. It is also very easy to install and replace, making it a popular choice for electrical equipment.

The FRS-R-20 fuse is a widely used electrical component that has a range of applications. It is used in a variety of switchgear and control equipment, power transmission, distribution systems, and other industrial applications. It is well-suited for applications in which short-term current interruption is required, and it provides a reliable and cost-effective solution for protecting electrical circuits.
