Fuses are electrical components used to protect circuits from excess current. They often have an internal element that will be damaged by a voltage spike or current overload, protecting the rest of the circuit from potential damage. One type of fuse, the 5ET 80-R, is often used in domestic and commercial applications. In this article, we will explore the application field and working principle of the 5ET 80-R fuse.

The 5ET 80-R fuse is designed to provide overload protection in AC or DC circuits, depending on its type. Generally, they can be categorized as a dual-element time-delay type. The fuse has an ability to withstand high current up to 200,000 amperes, and it provides extremely fast short-circuit fault response with a 100A rating of 60 cycles. The epoxy-filled tube material makes them highly resistant to shocks and vibrations. The 5ET 80-R can be used in situations where a higher level of current protection is necessary, such as in electronic circuits. The fuse also provides superior flexibility in terms of its mounting options, allowing for a wide variety of housing options.

The 5ET 80-R fuse is designed to protect the wiring of an electrical circuit from excess current. When the current flowing through a circuit exceeds the initial setting, the fuse melts. This causes a break in the circuit, preventing further damage or dangerous current fluctuations. The 5ET 80-R comes with a number of ratings, allowing for a range of protection levels. The rated current rating is the amount of current that the fuse will safely pass through the circuit before it melts. The higher the rating, the more current it can handle, and the lower the rating, the less current it can handle.

The working principle of the 5ET 80-R is based on a temperature-sensing principle. The device is designed with a bimetallic strip, which is made from two layers of metal material. When current passes through the fuse, the strip bends due to the resulting heat buildup, which in turn causes an internal contact to break the circuit. The fuse also has a “time-lag” feature, which allows the circuit to function for a short period even if the current exceeds its rated value. This is done so that the power can be cut off before any damage is done to the circuit.

The 5ET 80-R is used in a wide variety of applications, ranging from consumer electronics to professional industrial equipment. In addition to its use for overload protection, it can also be used as a component in protective circuit breakers, which are devices that work similarly to fuses but offer more control and protection. They are often used in places where excess current can become a problem, such as in power distribution systems or large machinery.

The 5ET 80-R is an extremely versatile and useful fuse for a wide range of applications and is one of the most popular types of fuse in the market. Its high current capacity, relative low cost, and superior reliability have made it the go-to choice for many different situations. Those who need an effective overload protection and a high level of control should look no further than the 5ET 80-R.
