Today, fuses provide a critical connection in the electrical systems of many types of vehicles, machines, and industrial and commercial equipment. As electrical systems become more complex, the need for fuses increases. But what exactly are fuses and how do they work?

In its simplest form, a fuse is an electrical device that contains an element designed to heat up when electricity flows through it. When the fuse element reaches a certain temperature due to current overload, it melts, thus breaking the circuit. This interrupts the flow of electricity, and prevents any further damage to the circuit or connected devices.

The WRS (Wire Resistive Screening) application field and work principle rely on the construction of the fuse element and the fuse body. It is designed to take the main current from a circuit to create a measurable voltage drop across the fuse\'s body. This is done by a tiny wire made up of two concentric, conductive strands that is embedded in the fuse body. The strands are made up of different metals such as copper, aluminum, or silver that have different resistive characteristics. The combination of these two strands creates a very small resistance within the fuse body, which produces a measurable voltage drop which is proportional to the amount of current flowing through the fuse.

The advantages of WRS technology lies within its ability to be tailored for small current applications. The fact that the resistance is measured in millivolt drops allows for much more precision than other methods that rely on more traditional resistive measurements. This also allows for the fuse to be used in high temperature applications up to 1000°C without failure. WRS is used in a variety of applications such as, protecting circuits in the automotive industry or high-temperature testing equipment.

In conclusion, WRS application field and work principle are an essential component of electrical systems. They offer protection from current overloads and act as safety devices to prevent electrical systems from shorting out or frying circuits. For all the advantages and protection they provide, it’s no wonder that WRS technology is becoming more and more common in industrial and commercial applications.
