14 Different Types of Fuses and Their Uses

 Fuses protect electrical circuits from the consequences of short circuits and overloads. And any other kind of unusual operating conditions that can cause damage to the circuitry. There are many different fuses, but they all serve the same purpose. 

Meanwhile, This guide will go over all the different types of fuses, explain how it works, and provide some examples of their most common uses.

You'll learn the different types and why you might need them. And in the end, you can choose the best fuse for your needs! Let's get started!

1. DC Fuses 

DC fuses are designed to protect electronic components from overcurrent and short circuits. These different types of fuses are used in a variety of applications. Including automotive, marine, and audio/visual equipment. 

DC fuses come in various sizes and amperages, so choosing the correct fuse for your application is essential.

2. Semiconductor Fuses

A semiconductor fuse is an electrical fuse made using a semiconductor material. These different types of fuses are used in electronic circuits to protect against overcurrent and short circuit conditions. They are often used in applications where space is limited, such as automotive electronics.

3. Resettable Fuses 

Resettable fuses are a type of fuse that can be used in a variety of applications. They are designed to protect overcurrents and short circuits. Resettable fuses are available in various sizes and styles to meet the needs of different applications.

4. Thermal Fuses 

A thermal fuse is a device that interrupts the flow of electricity in a circuit when the temperature gets too high. This fuse is used in appliances like hair dryers and toasters to protect against fires. Thermal fuses can also be found in car engines, where they're used to prevent overheating.

5. Rewirable Fuses 

Rewirable fuses are also different fuses that can be used multiple times. They have a screw-in base that allows you to replace the fuse wire easily. These fuses are often used in homes and businesses. 

6. Time-Delay Fuses

Time-delay fuses allow a higher current flow for a short period without blowing. This is helpful when devices with high inrush currents are turned on, such as motors. These different types of fuses are often used in industrial settings. 

7. SMD Fuses (Surface Mount Fuse), Chip, Radial, and Lead Fuses

An SMD fuse is a type of surface-mount fuse used in electronic equipment. These fuses are often used in cell phones, computers, and other electronic devices. 

Chip fuses are another type of surface-mount fuse. These fuses are used to protect sensitive electronic components from damage. 

Radial fuses are a type of leaded fuse. These fuses are often used in electrical panels and other types of equipment.

8. Automotive, Blade Type & Bolted Type Fuses

An automotive fuse is a low-resistance resistor that acts as a safety device to protect the circuit from excessive current. 

A blade-type fuse is a glass tube with a metal strip inside that melts when too much current flows through it, breaking the circuit. A bolted fuse is similar to a blade type but has a screw-in base that makes it easier to replace. 

9. High Voltage Fuses

High voltage fuses protect equipment subject to high voltages, such as transformers, from damage. These different fuses work by interrupting the flow of electricity when there is an overload, which prevents the equipment from being damaged by the excessive heat that would otherwise be generated.

10. HRC (High Rupturing Capacity) Fuse or Link Type Cartridge Fuse

HRC fuse is used for circuit protection in high voltage applications. It is made of two pieces of metal linked together with a copper conductor. 

The link-type cartridge fuse is also used for high voltage applications, but it is made of a single piece of metal with a hole in the center. This fuse is designed to break the circuit if the current flowing through it exceeds the rated value.

11. D – Type Cartridge Fuse

A D-type cartridge fuse is a cylindrical-shaped device used to protect electrical circuits. The fuse element is made of a metal alloy with a low melting point. 

This is one of the different types of fuses that are used in electronic equipment. Such as computers and stereos, where space is limited.

D-Type cartridge fuses come in different sizes, the most common being the 5mm x 20mm size. These fuses are available in different amperage ratings, which are typically 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 9A , 10A , 15A , 20A , 25A , 30A , and 35A .

12. Cartridge Fuses 

Cartridge fuses are different types of fuses containing a ceramic or glass tube with a metal end cap. The wire inside is usually made of copper or aluminum. 

In addition, the tube is filled with a non-conductive material, such as sand. When the current flowing through the fuse exceeds the rating, the wire inside will heat up and melt the non-conductive material around it, breaking the circuit.

13. AC Fuses

An AC fuse is one of the different fuses used to protect against the excessive current in an AC circuit. In addition, AC fuses are designed to open (disconnect) the circuit when the current flowing through the fuse exceeds the rated value. This prevents damage to the wiring and other components in the circuit. 

AC fuses are available in a variety of sizes and ratings. Moreover, the most common size ratings for AC fuses are 1/4, 1/2, and 1. 

AC fuses are made of various materials, including glass, ceramic, and metal. The type of material used in an AC fuse depends on the application. 

14. Overvoltage Suppression fuse 

An overvoltage suppression fuse is used to protect against voltage spikes. Lightning strikes or other electrical surges can cause these. Overvoltage suppression fuses are available in various voltages, so you can choose the one that best suits your needs.

Conclusion

In conclusion, knowing the different types of fuses and their uses is essential. We hope this blog post has helped you! It's hard to keep up with all the wiring terminology. But now that you have a little more knowledge, you'll be better equipped to tackle any project.
