Cooper Bussmann FRS-R-60 Fusetron Time Delay Fuse

Cooper Bussmann FRS-R-60 Fusetron Time Delay Fuse is a 60-amp, 600 VAC / 300 VDC rated UL Class RK5 dual-element time-delay fuse used to protect branch circuits in industrial and commercial equipment. As part of the Fusetron FRS-R family, it delivers current-limiting protection with a time-delay characteristic to accommodate brief inrush currents seen in motors and power supplies. The non-indicating device has an interrupting rating up to 200 kA at 600 VAC and 20 kA at 250 VDC, and is specified for use in standard RK5 fuse holders. The FRS-R series spans 1 A to 60 A, with the 60 A variant occupying the high end of the range; there is also an indicating variant, such as the FRS-R-60ID, which includes open-fuse indication.
