2JS 400-R Fuses - Application Field and Working Principle

2JS 400-R fuses are popular multi-standard fuses used for overload and short-circuit protection of electrical and electronic load systems. 2JS 400-R fuse links are widely used in industrial, commercial and residential applications, often in higher-rated assemblies, or as stand-alone, single-point protection devices. This article will discuss the application field and the working principle of 2JS 400-R fuses.

Application Field

2JS 400-R fuses are suitable for protecting circuit components such as motors, transformers, generators, motors, batteries, cords and switches. They can also be used in the protection of electronic circuits in distribution control and automation systems, communications systems and computer networks. Applications include industrial control switchgear, CTs and RTs, and even small-scale systems and appliances.

Working Principle

The working principle of 2JS 400-R fuses is that when an overload or short-circuit current flows through an appliance or device protected by the fuse, the electrical energy is converted to heat. This heat causes the fuse element to melt, thus cutting off the current flow and protecting the circuit from further damage. The fuse element of the 2JS 400-R fuse can be made of copper, brass, silver or other materials. The usual operating voltage for these multi-standard fuses is AC and DC 690V. It is important to note that fuse ratings and time-current characteristics should be chosen to match the expected loading of the device or circuit, so as to ensure that the fuse is able to operate effectively and safely.In addition to the fuse element, 2JS 400-R fuses also contain all the necessary components such as the fuse holder, mounting bracket, and end fittings. The fuse holders come in many shapes and sizes, designed to fit various electrical applications and enclosures. The fuse holders are often made of materials such as aluminum, stainless steel, thermosetting plastics, and brass. The mounting brackets for the 2JS 400-R fuses can be of a few different types, mountable on both flat and round surfaces, or they can have built-in clips for direct mounting on a flat surface. The end fittings are designed to store and seal the fuse elements in the event of a fuse failure or disconnection.

Conclusion

In summary, 2JS 400-R fuses are multi-standard fuses used for overload and short-circuit protection of electrical and electronic load systems. These fuses are suitable for a wide range of applications, from industrial to commercial and residential, and offer quick and reliable protection of various circuit components and systems. The component parts of the 2JS 400-R fuse, such as the fuse holders, brackets, and end fittings, are correctly matched to ensure reliable and safe operation.
