Bussmann FRN-R-30 Fusetron Current-Limiting Fuse

Bussmann FRN-R-30 Fusetron Current-Limiting Fuse is a 30 A, 250 VAC time-delay, dual-element fuse in the RK5 family with ferrule-end terminations and non-indicating construction. It provides a 200 kA interrupt rating at 250 VAC and 20 kA at 125 VDC, ensuring reliable protection for circuits subject to brief surge currents while keeping fault-clearing fast. The cylindrical body measures 9/16 in diameter by 2 in length and is designed to fit standard RK5 fuse holders. As part of Eaton's Bussmann FRN-R line, this robust current-limiting fuse protects branch circuits and equipment in electrical panels and power-distribution setups where startup surges occur but quick interruption of a fault is essential.
