Mersen TR80R - TR Class RK5 Fuse 80A 250V (200kA AIC Rating)

Mersen TR80R is a low voltage current-limiting fuse designed for industrial circuit protection applications. This RK5 class fuse features a 250V AC voltage rating and 80A current rating with 200kA interrupting capacity at 250V AC for reliable short-circuit protection. The single-barrel construction measures 1.06 inches in diameter and weighs 5.19 lb, utilizing time-delay characteristics to prevent nuisance tripping from motor starting currents. Compliant with industry standards for current-limiting fuses, this Tri-Onic family device provides coordinated protection in industrial power distribution systems. Typical applications include motor branch circuits, transformer protection, and feeder circuits where high interrupting capacity and selective coordination are required.
