Bussmann FRN-R-15 Cylindrical 15A safety fuse

250V, 15A Fusetron fuses are on average 23% more energy efficient than the next leading brand.

- Separate overload and short-circuit elements provide time delay for sizing as close as 125% of motor FLA.
- 2:1 selective coordination amp ratio (within the Cooper Bussmann RK5 fuse family) prevents overcurrent events from opening upstream Fusetron fuses.
- Insulated end caps for 225A-600A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing.
- Easy upgrade for one-time and renewable fuses installations. Because the Fusetron Class RK5 fuses fit any Class K5 or H fuse blocks and holders, you now have the opportunity to upgrade your circuit protection and save even more.
- Open fuse indication available on 8-60 amp ratings. See Data Sheet # 1169 below for details.
