Fuses are devices that are used to protect circuits by interrupting the flow of current when the current reaches a predetermined value. The BK/PCC-3/4 fuse is a popular type of fuse that is used in many applications. This article will discuss the application field and working principle of the BK/PCC-3/4 fuse.

Application Field

The BK/PCC-3/4 fuse is commonly used in the automotive industry. It is used as a safety circuit breaker for automotive electrical systems. Additionally, it is used in other industries such as manufacturing and medical technology. In the medical field, it is used to protect sensitive electronic equipment from damage due to voltage or current fluctuations.

Working Principle

The BK/PCC-3/4 fuse is a time-delay fuse. It works by detecting a sudden increase in current, and then delaying the opening of the fuse until a predetermined level is reached. The predetermined level is usually specified in the device’s technical specifications. This delay allows the fuse to absorb a large amount of energy without tripping. When the current reaches the specified level, the fuse will open and interrupt the current flow, thus protecting the circuit.

The BK/PCC-3/4 fuse also has a small, cylindrical thermistor embedded in the fuse element. This thermistor is designed to detect a rise in temperature due to excessive current. When the temperature rises above a certain point, it will cause the fuse to open, thus protecting the circuit from reaching dangerous levels of current.

The BK/PCC-3/4 fuse is designed to offer reliable and efficient protection. It is constructed from a combination of metal and plastic, making it highly durable and reliable. This makes it ideal for use in harsh environments. Moreover, it is easy to install and has a long service life.

Conclusion

In conclusion, the BK/PCC-3/4 fuse is a popular type of fuse that is used in many applications. It is designed to offer reliable and efficient protection by detecting sudden increases in current. Additionally, it has a small thermistor that is designed to detect a rise in temperature. This makes the fuse ideal for use in harsh environments. This article has discussed the application field and working principle of the BK/PCC-3/4 fuse.
