Cooper Bussmann FRS-R-2 RK5 Class Fuse 600V AC 2A

FRS-R-2 is a Bussmann series Class RK5 fuse (Fusetron) with time-delay, dual-element construction rated at 2 A and 600 V AC, engineered to protect 600 V circuits while tolerating brief inrush currents and allowing selective coordination in electrical panels and distribution gear. It is a non-indicating device with an interrupting rating of 200 kA at 600 VAC and 20 kA at 300 V DC, aligning with UL Class RK5 safety standards and delivering reliable fault interruption for high-energy circuits. As part of the FRS-R family in the Bussmann/Eaton catalog, this fuse provides current-limiting protection and a dual-element design that helps limit arc energy and improve safety during fault events. The 2 A, 600 V RK5 FRS-R-2 is suited for protection in 600 V distribution schemes and appliance and equipment enclosures, where fast clearance of faults must be balanced with tolerance for startup surges and inrush currents.
