Electrical Specialty Fuses

Specialty fuses are an important part of electrical distribution systems and can be used to protect a variety of critical components, appliances, and machines. The FWS-8A20F is one such fuse. This article provides an overview of the FWS-8A20F\'s application field and working principle.

Application Field

The FWS-8A20F is an AC Class L Single Pole Multi-Lock Fuse. This type of fuse is primarily used in outdoor and industrial locations. It is designed to be used in loose-fit fuse holders, with a transparent cover for protection.

The FWS-8A20F is designed for both indoor and outdoor installation in systems with an operating voltage of up to 1000 volts and a rated current of up to 8 amps. This fuse is suitable for use in a wide range of environments including wet or damp locations, marine environments, and more.

Working Principle

The FWS-8A20F works by allowing current to pass through a narrow metal strand. When the current flow is too high, the metal strand heats up and eventually melts, thereby “tripping” the fuse and breaking the circuit. This prevents the circuit from becoming overloaded and potentially damaging electrical components.

The FWS-8A20F also features a unique multi-lock design. This design ensures that the fuse stays securely in place, and prevents it from being accidentally pulled out. The fuse has a special diverter icon that helps indicate when the fuse has tripped.

The FWS-8A20F comes with a range of safety features, such as built-in over-load protection and fast-acting protection against short-circuits. Additionally, the fuse itself is rated to UL 248-14 standard, which ensures the highest level of safety and quality.

Conclusion

The FWS-8A20F is a specialty fuse designed for outdoor and industrial electrical systems. It features a multi-lock design and is rated for use in a wide range of environments. The fuse is designed to trip when the current flow is too high, thus preventing the circuit from becoming overloaded and potentially damaging electrical components. Additionally, the FWS-8A20F comes with a range of safety features and is rated to UL 248-14 standard, ensuring the highest level of safety and quality.
