FWA-800A

The FWA-800A is a versatile specialty fuse that is specially designed for the safety of electronic circuits and components. This fuse is designed to protect electronic circuits against short circuits, overvoltage, and over-temperature conditions. It is commonly used in applications such as electric motors, transformers, lighting systems, and power supplies. This article will discuss the application fields and working principles of the FWA-800A.

Applications

The FWA-800A is a suitable solution for electrical system applications in areas such as commercial, industrial, and residential settings. It is used to safeguard sensitive electronic components and circuits from common electrical faults such as short circuits, overvoltage, and over-temperature conditions. This fuse is also often used as an additional safety measure to protect against current surges. It is used to protect equipment such as motors, transformers, and power supplies from high-level current faults and damage. The FWA-800A is UL and CSA certified, which provides further assurance of its safety and reliability. This fuse is designated to UL 248-14, CSA C22.2 No. 248.14, and meets UL 1950 and CSA C22.2 No. 950 requirements. The FWA-800A is designed to trip within 5 minutes at 500VAC when exposed to a sustained overload or 500Vac short circuit.

Working Principle

The FWA-800A is a type-1 power distribution fuse. It operates according to the melting action principle, where the electrical current passing through the fuse causes an element inside of the fuse to heat up and melt, interrupting the flow of the current. This melts the fuse element, which then opens up to disconnect the circuit. By going through this process, the fuse is able to trip within 5 minutes at 500VAC when exposed to a sustained overload or 500Vac short circuit. The FWA-800A is a versatile fuse that offers a wide range of operating currents and interrupting ratings. Its interrupting rating is 5kA at 500VAC, and it is designed to accept operating currents ranging from 0.1A to 80A. It has a voltage rating of 500VAC, and is designed for both AC and DC applications. The FWA-800A also has high shock and vibration resistance.

Conclusion

The FWA-800A is a specialty fuse that is designed to protect electronic circuits and components from short circuits, overvoltage, and over-temperature conditions. It is UL and CSA certified and operates on the melting action principle. This fuse is versatile, offering a wide range of operating currents and interrupting ratings, and has high shock and vibration resistance. This fuse is ideal for applications such as electric motors, transformers, lighting systems, and power supplies.
