When designing commercial and industrial equipment, the safety of the equipment is extremely important. One of the most effective ways to ensure the safety of equipment is by using a fuse. While a variety of different types of fuses exist, the JJS-20 fuse stands out for its combination of small size and superior performance. Below we will discuss the application field and working principle of a JJS-20 fuse.

The JJS-20 fuse is primarily used in low-voltage control systems. It is designed for use with inductive loads, and is particularly suitable for use in short circuit protection and in motor start-up operations. It is also suitable for controlling the main AC power supply for electronic circuits and other equipment.

The JJS-20 fuse is a small and lightweight design, making it ideal for applications where space is at a premium. The fuse casing is made of a high-grade flame retardant plastic material, and the internal contacts are made of a special heat-resistant alloy. As a result, the JJS-20 fuse is able to withstand high temperatures and power surges without damage.

The JJS-20 fuse is a two-pole fuse, meaning that it has two connection points. The fuse is connected to the electrical circuit on one side and to the terminal on the other side. When the current exceeds the rated value, the fuse reacts by melting, thus disconnecting the circuit. The JJS-20 fuse also features an internal bimetal strip, which helps to reset the fuse after it has melted.

The JJS-20 fuse is manufactured in a wide range of ratings. The ratings range from 0.25A to 125A and are available in various voltage classes. As a result, it is suitable for both DC and AC applications. The fuses come in a variety of different shapes and sizes, so they can be easily mounted in most types of equipment.

The working principle of the JJS-20 fuse is the same as any other fuse. When the amperage exceeds the rated value of the fuse, the bimetallic strip inside the fuse will heat up due to the current. The heat generated will cause the bimetallic strip to bend, which will cause the fuse to melt. The melting of the fuse will then cause a break in the circuit, thus preventing the flow of current.

In summary, the JJS-20 fuse is a small and lightweight fuse that is ideal for use in low-voltage control systems. It is made of high-grade materials and is capable of withstanding high temperatures and power surges. The fuse is designed with two connection points and is available in a variety of ratings and voltage classes. It is easy to mount in most types of equipment. The fuse operates by melting when the amperage exceeds the rated value of the fuse, thus interrupting the flow of current.
