Littelfuse FLSR004ID - RK5 Time-Delay Fuse 4A 600V (200kA AIC)

Littelfuse FLSR004ID is a UL Class RK5 dual-element time-delay fuse with visual indication, designed for overcurrent protection in low-voltage circuits. It features a 600V AC/DC voltage rating and 4A current rating with a 200kA interrupting capacity at 600V for robust short-circuit protection. The fuse has a compact ferrule connection design with a 0.81-inch diameter barrel and weighs 0.18 lb, constructed for durable performance in industrial environments. Compliant with UL Standard 248-12 and CSA certifications, it meets stringent safety requirements for electrical protection. Typical applications include motor control centers, transformers, and power distribution equipment where time-delay characteristics prevent nuisance tripping during temporary inrush currents.
