BUSSMANN FRS-R-125 Dual Element Time Delay Fuse

FRS-R-125 is a 125 A, 600 V AC / 300 V DC dual-element time-delay fuse from Eaton's Bussmann Fusetron family (Class RK5), a UL-listed current-limiting device designed to protect power distribution and control circuits while tolerating brief inrush. As a current-limiting, non-indicating device, it carries an interrupting rating of up to 200 kA at 600 VAC and 20 kA at 300 VDC. Suitable for electrical and industrial circuits requiring robust short-time protection, the FRS-R-125 is commonly used in branch circuits and equipment where bursts of high current can occur. Available from Eaton Bussmann and major distributors (including DigiKey, Grainger, and Platt Electric Supply), the FRS-R-125 is documented as a 125 A, 600 V class RK5 dual-element time-delay fuse.
