An electrical fuse is a device used to protect circuitry by providing an intentional break in the flow of electricity when an unsafe level of current is flowing. Specialty fuses provide safer, more reliable power system protection, less downtime in the event of a fault, and smaller, less expensive protection devices. FWS-2A20F is one of the most popular specialty fuses today. This article will discuss its application field and working principle.

Application Field of FWS-2A20F

FWS-2A20F is a medium voltage fuse with a rating of up to 15kV. It’s designed for use in protecting both low and medium voltage power systems. FWS-2A20F fuses are suitable for use in systems ranging from 1.5kV to 15kV. It is ideal for industrial and heavy commercial applications.

FWS-2A20F is suitable for use in a variety of industries, ranging from oil and gas to renewable energy and water treatment. It is also ideal for medium voltage systems that are subjected to voltage surges. FWS-2A20F is designed to provide reliable protection to power systems from overloads, short circuits and internal faults, like electric arc and ground faults.

Working Principle of FWS-2A20F

FWS-2A20F operates by sensing current flow in the circuit it is protecting. When the current level exceeds the pre-set limit, the fuse will open the circuit, cutting off the electrical power supply. The purpose of this is to protect the system from damage due to over-voltage or overload risks. The fuse is designed to act very quickly, so that it can break the circuit within tens of milliseconds.

FWS-2A20F also has a secondary protective element called a blowout coil. This element senses current flow and provides a greater level of current control than the fuse alone. When the current levels reach a preset point, the Blowout Coil will act to reduce the current flow and help protect the system.

FWS-2A20F also includes an indicator window. This window is used to indicate the operational status of the fuse. The indicator window is illuminated when the fuse is closed; if it is not illuminated, it means that the fuse has tripped. This helps to minimize downtime due to circuit faults, as it allows technicians to quickly identify the issue.

Conclusion

FWS-2A20F is a popular specialty fuse which can be used in a variety of applications. It is designed for medium voltage systems ranging from 1.5kV to 15kV, and can provide reliable protection against a variety of system risks. The fuse operates by sensing current flow, and when the current levels exceed the pre-set limit, it will open the circuit, cutting off the electrical power supply. Additionally, the indicator window will help technicians to quickly identify if and when the fuse has tripped.
