Introduction to Fuses

Fuses are special electrical devices that are designed to protect electric circuits and components from overloads. They are safety devices that are used to prevent electrical circuits from current overloads and disconnect them from the power supply in case of a short circuit. The purpose of a fuse is to act as a “last resort” option to protect the circuit from extremely high currents that can damage the electrical components or cause a fire. It works by providing a safe outlet for excess current flow that is up to the maximum current limit or overload threshold, thus preventing further damage to the circuit.

BK/C515-2-R Fuse Application Field and Working Principle

The BK/C515-2-R fuse is a ceramic body, rewireable fuse. It is designed to protect circuits in electrical panels, motor control centers, distribution panels, and telecommunications equipment. It offers temperature-independent time-delay (TID) protection and is available in ratings ranging from 6.3 A to 30 A.The working principle of the BK/C515-2-R fuse is simple – it cuts off the supply of current in the circuit in case of a power overload. It consists of a strip of metal wire, known as a fuse element, which is connected to a piece of ceramic insulating material. When a short circuit or an overload situation occurs, the high current passing through the element causes it to blow and breaks the circuit, thus protecting the components in the circuit. Furthermore, the BK/C515-2-R fuse features a high interrupting capacity of 10 kA at 480 VAC, making it suitable for use in heavy-duty applications. It also has a high current-interrupting rating of 300A, making it ideal for protecting motor circuits. A unique feature of this fuse is that it also offers temperature-independent time-delay protection, ensuring that the circuit is not disconnected in the event of a sudden power surge.

Conclusion

The BK/C515-2-R fuse is a rewireable fuse that is designed to protect circuits in electrical panels, motor control centers, distribution panels, and telecommunications equipment. It features a high interrupting capacity and current-interrupting rating, as well as temperature-independent time-delay protection, making it a reliable safety device for heavy-duty applications. It works by providing an outlet for the excess current up to the overload threshold, thus preventing further damage to the circuit.
