KTN-R-100 - 100Amp Fuse

KTN-R-100 - 100Amp Fuse

When you're replacing a fuse, matching the amperage is only the beginning. The Eaton Bussmann KTN-R-100 is a 100A Class RK1 fuse rated at 250 Vac and 250 Vdc, with manufacturer-listed interrupt ratings of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. Its construction includes a melamine glass tube, one element, blade-end x blade-end connections, and 70/30 brass end caps. For replacement work, compare the full specification—KTN-R-100 catalog number, 100A rating, 250V AC/DC ratings, Class RK1 designation, interrupt ratings, connection style, and dimensions—with the equipment documentation before installation.

Key Features and Benefits

• 100A rating gives electricians and maintenance personnel a clear amperage specification for equipment matching.
• Rated for 250 Vac and 250 Vdc, allowing you to check the voltage specification for either listed AC or DC requirements.
• Class RK1 classification makes fuse-class identification straightforward during replacement and maintenance work.
• The blade-end-to-blade-end connection gives technicians another physical characteristic to verify before installation.
• The manufacturer specifies a melamine glass tube for the fuse construction.
• Single-element configuration helps distinguish the KTN-R-100 when comparing detailed fuse specifications.
• 70/30 brass end cap construction is specifically listed as a product feature.
• Non-indicating configuration is clearly identified for buyers who need to match the existing fuse type.

Material Compliance and Certifications

The manufacturer information supplied for the KTN-R-100 lists compliance as "Not Applicable." No additional compliance marks or certifications are claimed here. For projects with specific material-compliance or certification requirements, check those requirements separately rather than assuming certifications from other products in the same fuse family also apply to this catalog number.

Where It Works Best

The Eaton Bussmann KTN-R-100 suits electrical equipment whose documented requirements call for a 100A Class RK1 fuse rated at 250 Vac or 250 Vdc, along with the applicable manufacturer-listed interrupt rating. Its blade-end x blade-end configuration, single-element construction, melamine glass tube, non-indicating design, and listed dimensions give technicians several additional points to check when matching an existing fuse.
