Bussmann FRS-R-60ID Fuse RK5 Time Delay Indicator

The Bussmann FRS-R-60ID is a 60 A, dual-element, time-delay current-limiting fuse in Eaton's Bussmann Series Class RK5 family, designed for 600 VAC and 250 VDC systems and featuring an indicating design that provides a visible status window to show fuse condition. It uses ferrule-end terminations and measures about 5.5 inches long, 1.84 inches high, and 1.84 inches wide, with a weight of roughly 0.25 lb, and is CE marked. The fuse delivers an interrupt rating of 200 kAIC at 600 VAC and 20 kAIC at 250 VDC, and typically responds within about 10 seconds at 500% of rated current. Its 60 A rating, dual-element RK5 construction, and time-delay characteristic make it suitable for protectors in combination starters, motor control centers, machinery disconnects, and power panelboards in industrial electrical systems.
