FRS-R-176 is a Bussmann FRS-R dual-element, time-delay fuse (Fusetron) in the 600 V class RK5 family, rated at 175 A for 600 VAC operation (300 V DC). It is designed for slow-blow protection and pairs with RK5 fuse holders, providing protection against short-circuit and inrush in industrial power circuits. The FRS-R family covers ratings from 1 A up to the 600 A range, making the 175 A variant suitable for branch circuits in motor drives, power distribution panels, and industrial control gear that require reliable slow-blow protection at high voltage.
