KTN-R-250 - 250Amp Fuse

KTN-R-250 - 250Amp Fuse

Fuse replacement starts with the equipment specification, and the Eaton Bussmann KTN-R-250 gives maintenance teams clear ratings to check. This 250A Class RK1 fuse is rated for both 250 Vac and 250 Vdc, with an interrupt rating of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. Whether you're checking a scheduled maintenance replacement or matching an existing fuse, comparing the catalog number, amperage, voltage, interrupt rating, fuse class, connection style, and dimensions gives you a much clearer picture than amperage alone.

Key Features and Benefits

• 250A Class RK1 rating: Clearly identifies the amperage and fuse class for straightforward specification matching.
• AC and DC rated: Listed for 250 Vac and 250 Vdc, giving technicians both voltage ratings in one model.

Where It Works Best

The Eaton Bussmann KTN-R-250 fuse is best suited for equipment specifications calling for a 250A Class RK1 fuse rated at 250 Vac or 250 Vdc, with the appropriate interrupt rating and blade-to-blade connection. Its specified 8.5 x 2.06 x 2.06-inch dimensions provide another useful checkpoint when confirming a replacement.
