The FWS-2A20FI is an electrical specialty fuse manufactured by the Cooper Bussmann electrical product company. This fuse is designed primarily for use in distribution boxes, switchboards, and other electrical installation applications for both residential and commercial properties. It is also used in some industrial applications which require protection from overload and short circuits.

The FWS-2A20FI is a type of Class RK5 dual element fuse which offer both short circuit and overload protection. It can be used on both AC and DC power systems from 50 to 600 VAC and up to 300 VDC. The fuse is rated for 35 kiloamps at 250 volts AC or 160 volts DC interrupting current, with a maximum voltage drop of 1000 volts. This fuse can be used with both fast-acting and low-breaking types up to 35 amperes on a single fuse, or up to a maximum of 80 amperes when two fuses are used in a double fuseholder.

The FWS-2A20FI has a unique design which inhibits the buildup of arcing energy which can cause damage to the fuse or other components in the system. It uses class J fuses which are self-righteous and designed to burn out quickly in overload or short circuit conditions, allowing the system to quickly shut down without causing damage. The design also includes current limiting elements which limit the amount of current the fuse can carry, reducing the amount of damage it can cause.

The FWS-2A20FI provides a reliable and efficient way to protect electrical installations from overloads and short circuits. It offers fast and reliable protection for most applications while also providing a cost-effective solution.
