KTN-R-12 - 12Amp Fuse Description
KTN-R-12 - 12Amp Fuse
Finding the right replacement fuse means checking more than the amp number on the label. The Eaton Bussmann KTN-R-12 is a 12A, 250V Class RK1 fuse with a single-element construction and non-indicating design. Because several electrical specifications can determine whether your fuse is the right match, check the KTN-R-12 catalog number, 12A rating, 250V rating, Class RK1 designation, dimensions, and element configuration before installation. For maintenance crews and electrical buyers, having those details together makes identifying the required replacement a lot more straightforward.

Material Compliance and Certifications
The manufacturer information supplied for the KTN-R-12 lists its compliance status as Not Applicable. The supplied specifications include no additional material-compliance certifications or approval marks, so I would not add or imply any that aren't documented.
Where It Works Best
The KTN-R-12 makes sense to consider when you're replacing a fuse, and the equipment documentation specifically calls for a 12A, 250V Class RK1 fuse with matching physical characteristics. Don't stop after matching the amperage. Check the class and voltage, then compare the 2 x 0.56 x 0.56-inch dimensions and single-element configuration.
That kind of side-by-side check is especially useful during maintenance, when an old fuse may have limited markings or when several similar-looking fuse ratings are on hand. Matching the full specification helps remove the guesswork in identifying the correct replacement.
