Bussmann FRN-R-30 is a low-voltage, time-delay fuse designed for branch circuit and feeder protection in industrial electrical systems. It features a 30A current rating and a 250V voltage rating, providing reliable overcurrent protection with a high 200kA interrupting capacity. The fuse is constructed as a single-barrel, RK5 class device with a compact form factor measuring 2" in length and 0.56" in diameter, weighing 0.05 lb. It complies with key industry standards including UL 248-12 and CSA Class 1422-01, and is typically applied in motor circuits, transformers, and other equipment where a time-delay characteristic is required to withstand harmless inrush currents.
