Bussmann FRS-R-175 600v 175amp Dual-Element, Time-Delay Class-RK5 Fuse

The Bussmann FRS-R-175 Fusetron Low Voltage Fuse is a 600V 175A Fuse. The FRS-R-175 is a 1 Barrel fuse. It features a diameter of 1.61. It has a AIC rating of 200kA@600V. They are able to tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. Also called slow-blow Class RK5 fuses, these 200kA IR fuses open to disconnect an electrical circuit when exposed to sustained loads and short circuits. They have no indicator for identifying a blown fuse, so they're sometimes used with an indicating fuse block or cover.
