KTN-R-70 - 70Amp Fuse Description
KTN-R-70 - 70Amp Fuse
Getting the amperage right is only one part of selecting a replacement fuse. The Eaton Bussmann KTN-R-70 is a 70A Class RK1 fuse rated at 250V, with manufacturer-listed interrupt ratings of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. Whether you're checking an existing KTN-R-70 or researching a replacement for equipment that specifies a 70A Class RK1 fuse, comparing the catalog number, voltage, interrupt ratings, class, and physical dimensions helps narrow the decision to the correct specification.
