Bussmann FRS-R Series Dual-Element Class RK5 Fuse, Ferrule End x Ferrule End
The Bussmann FRS-R series is an Eaton Bussmann dual-element, Class RK5 fuse with indicator, built for ferrule end x ferrule end fuse holders in commercial and industrial electrical systems. This time-delay fuse carries a 10 second at 500% response characteristic along with high interrupting ratings of 20 kAIC at 300 Vdc and 200 kAIC at 600 V, and is rated Standard 600 V / 300 Vdc. The FRS-R series is available in 11 amp ratings from 6A to 50A (6A, 8A, 9A, 10A, 15A, 20A, 25A, 35A, 40A, 45A, 50A), letting electricians, panel builders, and OEMs match the correct amperage to the specific circuit being protected while standardizing on a single dual-element fuse family.
Key Features
- Amp Rating Range: Available in 11 selectable amp ratings – 6A, 8A, 9A, 10A, 15A, 20A, 25A, 35A, 40A, 45A, and 50A – to match a wide range of circuit protection requirements.
