What are the different types of cylindrical fuses?

In modern electrical systems, fuses play an indispensable role as an important component to protect circuit safety. In particular, cylindrical fuses are widely used in various industrial, household and automotive fields due to their compact structure and convenient installation. So, what are the different types of cylindrical fuses? How to choose the right product according to your needs? Below, we will answer them one by one for you.

1. Classification by fusing speed

1. Fast-Acting Fuse

Fast-acting fuses can quickly cut off the circuit when the current exceeds the rated value, effectively preventing the components from overheating and damage. They are particularly suitable for protecting sensitive electronic components, such as semiconductors, capacitors, etc., which are very sensitive to instantaneous current changes.

2. Time-Delay Fuse

Unlike fast-acting fuses, slow-acting fuses allow the circuit to withstand higher surge currents for a short time, such as the instantaneous high current generated when the motor starts and the power supply equipment starts. They can resume normal operation after a short impact to avoid downtime due to false operation.

2. Classification by voltage

1. Low-voltage cylindrical fuse

Usually used in household appliances, electronic products and low-voltage industrial equipment. The design voltage of this type of fuse is generally within a few hundred volts, with a small size and sensitive response.

2. High-voltage cylindrical fuse

Used in high-voltage switchgear, transformers and large industrial equipment. High-voltage fuses not only require strong current-breaking capacity, but also excellent insulation performance to cope with the harsh environment brought by high voltage.

3. Classification by material structure

1. Ceramic shell cylindrical fuse

Using ceramic as the shell material, it has excellent high temperature resistance, impact resistance and combustion resistance, and is suitable for occasions requiring high current-breaking capacity, such as industrial control systems, power equipment, etc.

2. Glass shell cylindrical fuse

The glass shell is transparent, and the fuse status can be observed intuitively, which is convenient for troubleshooting and maintenance. It is suitable for household appliances and small electrical equipment that need to monitor the fuse status.

4. Classification by size standard

1. American standard (UL standard) fuse

The size and performance meet the UL certification standards, mainly sold to the North American market, and commonly used in electronic equipment, industrial control equipment, etc.

2. European standard (IEC standard) fuse

It meets the International Electrotechnical Commission (IEC) standards and is widely used in Europe and other international markets. It has a wide variety and covers all kinds of electrical application needs.

Choosing a suitable cylindrical fuse is not only related to the safety of the electrical system, but also directly affects the operating efficiency and life of the equipment. When selecting, it is necessary to comprehensively consider factors such as voltage level, fusing speed, use environment and certification standards.
