Where It Works Best

The Eaton Bussmann KTN-R-80 80A fuse is appropriate to evaluate when equipment documentation calls for a Class RK1 fuse rated at 80A and 250 Vac or 250 Vdc. The application should also align with the specified 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc interrupt ratings, as applicable, along with the blade-end connection and physical dimensions.
