Littelfuse FLSR-090 - RK5 Time-Delay Fuse 90A@600V (200kA AIC)

Littelfuse FLSR-090 is a low-voltage time-delay fuse from the Powr-Gard family, designed for circuit protection in industrial electrical systems. This RK5-class fuse features a 600V AC/DC voltage rating and 90A current capacity with a 200kA interrupting rating at 600V for reliable overcurrent protection. The compact 1.31-inch diameter plug-in design measures 15/6" in diameter x 7-7/8" in length and weighs 0.6 lb, constructed with durable materials for industrial environments. Compliant with UL/CSA standards, it provides selective coordination in panelboards and switchgear applications where time-delay characteristics are required to withstand temporary inrush currents.
