The Cutler Hammer A2K80R is a Class RK1 low-voltage current-limiting fuse designed to provide reliable overcurrent and short-circuit protection in industrial electrical systems. It features a 250V AC voltage rating and a 80A current rating, with a high 200kA interrupting capacity at 250V for superior fault protection. The fuse construction includes a single-barrel design measuring 1.06 inches in diameter and 5.88 inches in length, weighing 0.38 pounds for compact installation. This RK1 class fuse meets industry standards for current-limiting performance, effectively reducing let-through current during fault conditions. Typical applications include motor branch circuits, feeder circuits, and industrial control panels where high-interrupting capacity protection is required.
