KTN-R-20 - 20Amp Fuse

KTN-R-20 - 20Amp Fuse

A replacement fuse may look simple, but getting the details right matters. The Eaton Bussmann KTN-R-20 is a 20A, 250V Class RK1 fuse built with a single element and a melamine glass tube. Its ferrule-to-ferrule connection and compact 2-inch length give maintenance teams clear physical characteristics to compare against your existing fuse and equipment requirements.

Key Features and Benefits

• 20A amperage rating gives you a precise electrical value to match against equipment requirements.
• Rated at 250V for applications specifying this voltage and fuse class.
• Class RK1 designation makes it easier to distinguish the KTN-R-20 from other fuse classes with similar amp ratings.
• The ferrule-to-ferrule end connection is an important physical detail when checking an existing fuse or fuse location.
• Melamine glass tube construction matches the manufacturer-listed material for this catalog number.
• The single-element design provides another specification to verify when selecting a replacement.
• 70/30 brass end caps are listed as a special feature of the KTN-R-20.
• Non-indicating configuration means the fuse does not use an integral fuse-status indicator.

Material Compliance and Certifications

The supplied manufacturer specifications list compliance as “Not Applicable” for the KTN-R-20. The provided product data includes no additional material-compliance certifications or approval marks, so we assume none. This matters when comparing similar fuse models because you should confirm certifications and compliance for the exact catalog number rather than carry them over from another product.

Where It Works Best

The Eaton Bussmann KTN-R-20 is a practical match to evaluate when equipment documentation calls for a 20A, 250V Class RK1 fuse with a single element and ferrule-end connections. Its physical specifications—2 inches long and 0.56 inches high by 0.56 inches wide—also give technicians concrete measurements to check when replacing an existing fuse.
