KTN-R-90 - 90Amp Fuse

KTN-R-90 - 90Amp Fuse

The Eaton Bussmann KTN-R-90 gives electrical buyers and maintenance teams clear specifications to check when equipment calls for a 90A Class RK1 fuse. Rated for 250 Vac and 250 Vdc, this single-element fuse carries manufacturer-listed interrupt ratings of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. Rather than relying on amperage alone, buyers can compare the catalog number, voltage, Class RK1 designation, interrupt ratings, dimensions, and other supplied specifications against your equipment documentation—a much more useful approach when confirming the correct replacement fuse.

Key Features and Benefits

• 90A amperage rating gives you a clear starting point when matching an existing KTN-R fuse or equipment specification.
• Rated for 250 Vac and 250 Vdc, allowing you to check the specified AC and DC voltage values directly.
• Class RK1 classification is an important detail to verify alongside amperage and voltage.
• Single-element construction matches the manufacturer's listed configuration.
• Listed as a non-indicating fuse.

Material Compliance and Certifications

The manufacturer information supplied for the KTN-R-90 lists compliance as: Not Applicable. The provided product data includes no specific construction material or additional certifications, so none are assumed here. Keeping those distinctions clear is especially important with electrical products, where specifications should come from documented product information rather than characteristics of similar models.

Where It Works Best

The Eaton Bussmann KTN-R-90 90A fuse is a good option when equipment documentation specifies a 90A, Class RK1 fuse rated for 250 Vac or 250 Vdc. Also check the application against the manufacturer-listed interrupt ratings of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc, as applicable.
