Littelfuse FLNR-070 - Class R Current-Limiting Fuse 700A 600V (200kA Interrupting Rating)

Littelfuse FLNR-070 is a low-voltage current-limiting fuse designed to provide reliable overcurrent protection in industrial electrical systems. It features a 700A current rating and 600V AC voltage rating, engineered to safely interrupt high fault currents. The fuse is constructed with a durable ceramic body and silver-plated copper end caps, ensuring stable performance and excellent arc-quenching capabilities. It complies with UL Class R rejection standards, preventing the installation of lower-capacity fuses in the same holder. Typical applications include protection of motor circuits, transformers, and feeder circuits in industrial control panels and power distribution equipment.
