Description
The FLNR-4 fuse is a Class RK5 time-delay fuse designed for general-purpose circuit protection. Manufactured by Littelfuse, it has a 4-amp rating and operates at 250V AC / 125V DC. This fuse features a dual-element design, providing advanced short-circuit and overload protection. The FLNR series is widely used in service entrance switches, transformers, switchboard mains, and motor control circuits. Its time-delay functionality allows it to tolerate temporary inrush currents without opening, preventing nuisance-blowing during motor and equipment startups.
