KTN-R-450 - 450Amp Fuse

KTN-R-450 - 450Amp Fuse

At 450 amps, there's little value in guessing whether a replacement fuse is the right match. The Eaton Bussmann KTN-R-450 gives maintenance teams and electrical professionals a clearly defined set of specifications to check before installation: 450A, Class RK1, and a 250 Vac/250 Vdc voltage rating. If you're replacing an existing KTN-R-450 or checking a fuse against your equipment documentation, these electrical and dimensional details make side-by-side verification much easier.

Key Features and Benefits

• 450A rating — clearly identifies the amperage for specification matching.
• 250 Vac and 250 Vdc ratings let you evaluate the model against equipment requiring the corresponding AC or DC voltage rating.
• Class RK1 classification makes it easier to compare the fuse with equipment documentation and an existing component.
• Single-element construction matches the manufacturer's listed physical configuration.
• The KTN-R-450 is listed as non-indicating.

Material Compliance and Certifications

The supplied manufacturer data for the KTN-R-450 lists compliance as: Not Applicable. The supplied product data specifies no material composition or additional certification information, so no additional compliance or certification claims are assumed.

Where It Works Best

The Eaton Bussmann KTN-R-450 fuse is best evaluated for equipment whose documentation calls for a 450A Class RK1 fuse rated at 250 Vac or 250 Vdc, along with the applicable interrupt rating. For AC requirements, the manufacturer lists 200 kAIC at 250 Vac; for DC requirements, the listed value is 100 kAIC at 250 Vdc.
