Fuses are a type of electronic device that utilizes a conductive strip or wire to open or close the flow of an electric circuit. They are often used to protect electrical equipment and circuits from overcurrents or short circuits. The 3AB 20-R is a type of fuse that can be used in a variety of electrical applications. In this article we will discuss the application field and working principle of the 3AB 20-R fuse.

The 3AB 20-R is a single use ceramic fuse designed for high voltage protection applications. This fuse is available in a variety of voltages ranging from 600 to 1500 Volts AC. It can be used in a variety of areas, including the protection of electronic circuits of all types of household appliances, power tools, rectifiers, solar systems, electromechanical relays, avalanche diodes, and fuses. This wide range of applications makes the 3AB 20-R an ideal choice for a variety of different applications.

The 3AB 20-R fuse works by utilizing an internally mounted resistor that is adjustable. This is done by changing the amount of current the internal resistor is capable of carrying. The resistor is then connected to a bimetal strip which is used to open or close the circuit in order to protect it from over current or short circuits. When a greater current than the adjustable resistor can carry is present in the circuit, the bimetal strip expands which then causes the circuit to open, thereby preventing damage.

The 3AB 20-R is a durable and reliable fuse with a wide application field. It is suited for a variety of voltages ranging from 600 to 1500 Volts AC and can be used to protect electronic circuits of all types of appliances, rectifiers, power tools, and fuses. The reliable and adjustable resistor ensures that the circuit is opened when necessary in order to protect it from over current or short circuits.

In conclusion, the 3AB 20-R is an ideal choice for a variety of electrical applications. It is an adjustable and durable single-use ceramic fuse that is suited for a wide range of voltages. It is also reliable, making it a great option for protecting electronic circuits of all types of appliances, rectifiers, and power tools. The adjustable resistor ensures that the circuits are opened when necessary to prevent any overcurrents or short circuits.
