Introduction to Fuses

Fuses are devices that are designed to protect circuits and safely interrupt electrical circuits when required conditions are met. Fuses can be used in a variety of applications, ranging from residential to industrial settings, to protect electrical equipment from damage due to overloads and short circuits.Fuses are typically cylindrical in shape and have two wires at the end, which are connected to the electric circuit. The fuses can be made from different materials and in different shapes and sizes to suit the need of the application.

BK/C519-2.25-R Fuse

The BK/C519-2.25-R fuse is a cylindrical-shaped, auto-recloser type fuse. It has a fixed metal strip connecting two ends of two wire terminations and is designed to automatically reclose after interruption due to overload or short circuit. This particular fuse is designed for use with 2.25mm wires and has an rated voltage of AC 690V.

Application Field

The BK/C519-2.25-R fuse is suitable for a variety of applications, such as in residential and commercial buildings, and in industrial settings. It can be used to protect electrical equipment from overloads and short circuits. It is particularly useful in applications where a significant amount of current is required, such as in electrical motors, air conditioners, and other large electrical appliances.

Working Principle

The BK/C519-2.25-R fuse works by first sensing any over-current flowing through the circuit. When the current exceeds the fuse’s rating, the metal strip melts, breaking the connection between the two wires. This interrupts the flow of electrical current, protecting the circuit from any further damage.Once the current has dropped below the transformer’s rating, the fuse will reset itself, restoring the circuit connection. This ability to automatically restore the circuit connection after an over-current has been interrupted makes the BK/C519-2.25-R a very useful safety device.

Conclusion

The BK/C519-2.25-R is a cylindrical-shaped, auto-recloser type fuse designed for use with 2.25mm wires and rated up to 690V AC. It is suitable for a variety of applications, including residential, commercial, and industrial settings. The fuse works by sensing any over-current, then breaking the connection between two wire terminations and interrupting the circuit. Once the current has dropped below the transformer’s rating, the fuse will reset itself and restore the circuit connection.
