KTN-R-175 - 175Amp Fuse

KTN-R-175 - 175Amp Fuse

When you’re replacing a high-amperage fuse, you want an exact match—not “close enough.” The Eaton Bussmann KTN-R-175 is a 175A Class RK1 fuse rated for 250 Vac and 250 Vdc, with a manufacturer-listed interrupt rating of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. Rather than stopping at the 175A rating, compare the KTN-R-175 catalog number, Class RK1 designation, AC/DC voltage ratings, interrupt ratings, element count, and dimensions against the equipment documentation before installation.

Key Features and Benefits

• 175A Class RK1 fuse for equipment requiring this specific amperage and fuse class.
• Rated for 250 Vac and 250 Vdc, giving you clear AC and DC voltage specifications to verify.
• Single-element construction provides another specific identifier for replacement matching.
• The non-indicating design means it has no built-in visual fuse-status indicator.

Material Compliance and Certifications

The manufacturer information supplied for the KTN-R-175 lists compliance as “Not Applicable.” The provided specifications include no additional certifications, approval marks, or material-compliance claims, so none are inferred here. For electrical components, that kind of accuracy matters—especially when similar products in the same series may carry different documentation.

Where It Works Best

The Eaton Bussmann KTN-R-175 is a practical fit for replacement situations where the equipment specification calls for a 175A Class RK1 fuse rated at 250 Vac or 250 Vdc and the required interrupt rating matches the application. Its single-element, non-indicating configuration gives maintenance personnel a couple of additional details to verify beyond amperage and voltage.
