Edison Fuses ECNR3 is a low-voltage current-limiting fuse designed for protecting electrical circuits and equipment from overcurrent and short-circuit faults. It features a 250V AC voltage rating and a 3A current rating, housed in a compact, single-barrel ferrule-style construction measuring 2 inches in length with a 0.56-inch diameter. This RK5 class fuse complies with industry standards for current-limiting performance, offering a high 200kA interrupting rating at 250V to safely clear major faults. It is typically applied in industrial control panels, motor branch circuits, and transformer protection where reliable, fast-acting protection is required.
