GFA-15/100

GFA-15/100 Application Field and Working Principle

GFA-15/100 fuses are used primarily in industrial applications. These heavy duty fuses consist of a glass body containing a high-temperature fuse link. This fuse link is designed to melt and open the circuit if the current exceeds the ratings of the fuse. This action limits the current in the protected circuits, thus preventing damage or injuries caused by over current.

GFA-15/100 fuses are commonly used for industrial circuit protection, particularly in circuits carrying higher loads. These fuses are designed for high inrush current and are designed to handle higher load currents than standard devices. The maximum current that can be tolerated by a GFA-15/100 fuse is 15 amperes (A), while the maximum voltage rating is 100 volts (V).

The working principle of the GFA-15/100 fuse is based on the Joule effect, which states that an element, such as a wire, produces heat when an electrical current is passed through it. When the current in the protected circuit exceeds the rating of a GFA-15/100 fuse, the heat generated in the fuse element increases. This increase in heat melts the fuse link inside the fuse body, thus interrupting the current and opening the circuit.

Apart from protecting against over current, GFA-15/100 fuses can also protect against short circuit, power overloads, and other faults. When these faults are present, the current in the protected circuit rises sharply. This leads to an increase in the heat in the fuse element, which causes the fuse element to melt and open the circuit.

GFA-15/100 fuses are widely used in numerous industrial applications such as motor control circuits, lighting circuits, heating circuits, power supply circuits, and many others. These fuses provide reliable protection against over-current conditions, while at the same time ensuring safe operation of the protected circuits.

In summary, GFA-15/100 fuses are heavy-duty devices that are designed for industrial applications. They are based on the Joule effect and provide protection against over current, short circuit, and power overloads. They are essential components in industrial circuit protection and should be used whenever possible in order to provide reliable protection against these issues.
