BK/PCF-2-1/2 Fuses - Application Field and Working Principle

Fuses are electrical safety components used to protect electrical networks and other components from damage due to overload or short circuit. Fuses are used in domestic, industrial and vehicle installations, electronic circuits, and wherever electrical protection is required. BK/PCF-2-1/2 fuses are specifically designed to provide reliable and effective protection in industrial installations.

Application Field

BK/PCF-2-1/2 fuses have a wide range of applications. They are primarily used in low-voltage industrial applications, such as power supplies, cable distribution networks, and motor protection. They are also suitable for overcurrent protection in residential and commercial buildings. Additionally, these fuses can be used in emergency, signaling, and other applications requiring reliable current limitation.

Working Principle

The BK/PCF-2-1/2 fuses work on the principle of a melting element. They consist of a conductor, an insulation tube, and a wire fuse element. Under normal functioning conditions, current is allowed to flow through the conductor. When an overload or short circuit occurs, the current flowing through the fuse will exceed its rated amperage. This causes the fuse’s element to heat up, eventually melting. This interrupts the flow of current and reliably prevents damage to the installation.

Special Features

BK/PCF-2-1/2 fuses have several advantages that make them suitable for a wide range of applications. They are relatively compact in size, making them suitable for many installation requirements. The fuse element also has a corrosion-resistant design that ensures reliable performance under varying conditions. Additionally, the fuse comes with a transparent cover that allows easy visual inspection of the fuse state.

Specifications

The BK/PCF-2-1/2 fuses have an operating voltage of up to 500 VAC. The rated current is 1 A, 2 A, and 4 A. The fuse elements have a rated breaking capacity of 50 kA. The operating temperature range of the fuse is between -40°C and +60°C. The fuse is also equipped with a special earthing terminal for protecting against overvoltage and transient overvoltages.

Conclusion

BK/PCF-2-1/2 fuses are reliable and effective solutions for overcurrent protection of electrical and electronic installations. Their advantages, such as compact size and reliable performance, ensure their suitability for a wide range of applications. Additionally, the special features of the fuse, such as transparent cover and earthing terminal, make them ideal for important safety requirements.
