2JS 6-R

In recent years, the development of industrial automation has made it necessary to use more advanced fuses. 2JS 6-R is a new type of three-phase fuse, which has many advantages compared with other types. The main feature of 2JS 6-R is its high current interruption capability and greater overload capacity. It can provide better overload and short-circuit protection to electrical equipment and extend its service life. In addition, it has excellent thermal stability and very low terminal resistance.

2JS 6-R is used mainly in electrical distribution systems, especially where high currents are present. It is commonly used in transformer and high voltage circuit breakers, and can be effectively used to protect cables from high short-circuit currents. In industrial lighting circuits, it can provide overload protection for transformers and other electrical equipment. It is also used widely in commercial and residential power distribution networks and is widely adopted in electric power, telecommunications, aerospace and other industries.

The working principle of 2JS 6-R fuse is determined by the constructional design of the fuse body and current-limiting principle. The fuselage is composed of three different materials: A bimetallic core, an insulated tube and an outer tube. The bimetallic core consists of two metals with different thermal expansion coefficients. When the fuse is excessive current, the inner core will move inward and break the contact between them and disconnect the circuit. The insulated tube is used to insulate the inner core from the external environment and improves the mechanical properties of the inner core. Finally, the outer tube is used to protect the bimetallic core and insulated tube from damage.

The working principle of 2JS 6-R also relies on its resistance to current. In the fuse, the contact area and current path length are smaller than other types of fuses, creating a larger resistance. When excessive current flows through the fuse, the heat generated by the resistance melts the fusible element, making the contact of the fuse open and cutting off the current. 2JS 6-R has a low thermal capacity, so it can react quickly and protect the equipment quickly.

Apart from being used in electrical and industrial applications, 2JS 6-R fuses also have other applications. It can be used in motors, home appliances and automotive circuits, and can also be used in the production of fireproof and waterproof enclosures. It is capable of providing reliable protection against short-circuit currents of up to 6,000 A. In summary, it is a reliable, durable and cost-effective solution to a wide range of circuit protection needs.
