Fuses

Fuses are electrical components used in electrical circuits, which allow them to connect and disconnect current. The primary purpose of a fuse is to protect the circuit from overloads or short-circuits. Fuses are also used to protect people from electrical shock. Fuses come in a variety of sizes and styles, ranging from the common cartridge fuse to the more complex circuit breakers.

The specific fuse being discussed in this article is model #7043.8220. This fuse is a cartridge type fuse, which means that it has two metal terminals located at each axial end, usually made from aluminum or copper. The bearings of the fuse are usually insulated and include a ferrule at each terminal. The ferrule holds the fuse link in place, which is a metal strip or wire that is connected between the two terminals. The fuse link is made from silver, silver and copper, or some other material.

When a direct current of too much power passes through the fuse link, it heats up until it reaches a point known as the melting point. At this point, the metal melts and the circuit breaks protecting the circuit from further damage.

The 7043.8220 fuse is primarily used for the following applications: window and domestic air conditioning; air motors, circuit breakers, and other electric circuit accessories, including wires and cables; DC power systems for automobiles and aircraft; and lighting control systems used in many industries.

This fuse model is also suitable for low voltage applications in 24V and 36V automotive systems. The 7043.8220 is ideal for both the on/off state or the overload current protection applications.

In terms of working principle, the fuse should be connected in series with the conductor terminals, as close as possible to the power source, in order to detect any overloads in the system. When an overload, or a short circuit, occurs, the fuse link will heat and melt, opening the circuit and protecting the device.

The 7043.8220 fuse is designed to be compatible with many types of circuits, including AC and DC circuits. The device is also easy to install and replace, as its construction consists of a simple two-wire terminal system. The fuse links can also be easily changed when the fuse link has reached its maximum current capacity.

In conclusion, the 7043.8220 fuse is a reliable and safe device for protecting circuits against overloads and short circuits. It is widely used in a variety of industries and applications, and features an easy-to-use installation system. Furthermore, it is designed to be compatible with both AC and DC circuits, allowing it to be used in a wide variety of applications.
