Fuses are one of the most common safety devices used to protect electrical circuits from damage due to excessive current. BK/C515-3-R is a type of fuse that is used to protect circuits from short-circuiting and is used in a number of electronic and electrical applications. In this article, we will discuss the application field and working principle of BK/C515-3-R.

BK/C515-3-R Application Field

The BK/C515-3-R is a very common medium-current fuse used in many applications, but the most popular application of this fuse is as a motor-starting fuse. It is commonly used in small appliances, such as refrigerators, washing machines, microwaves, and electrical heaters. It can also be used to protect circuits from short-circuiting, or to protect motors from damage due to overloads.

BK/C515-3-R Working Principle

The BK/C515-3-R fuse is composed of a heat-resistant material with a low melting point. This material is wrapped in a wire which acts as a conductor. When the current flowing through the fuse exceeds the rated value, the temperature of the fuse increases and the fuse material melts, which interrupts the circuit and cuts the power.

This type of fuse also contains a current-limiting resistor, which limits the current and prevents overcurrent damage. When the resistance of the resistor is exceeded, the material begins to melt and interrupts the circuit. The melting point is adjustable, which allows the fuse to be set to the desired level of protection.

The BK/C515-3-R fuse is not designed to protect against short circuits. It can provide protection against overloads, but does not protect against short circuits. For this type of protection, another type of fuse with a higher current rating is recommended.

Conclusion

The BK/C515-3-R is a type of fuse used to protect circuits from overloads and is commonly used in small appliances. It is composed of a heat-resistant material with a low melting point -wrapped in a conductor which melts when overcurrent flows through the wire. It also contains a current-limiting resistor which limits the current and prevents overcurrent damage. However, it is not designed to protect against short circuits and should not be used for this purpose.
