KTN-R-7 - 7 Amp Fuse

KTN-R-7 - 7 Amp Fuse

When you’re replacing a fuse, getting the details right matters more than getting close. The KTN-R-7 is a 7-amp, 250V AC Class R fuse with a fast-acting, current-limiting design and a 200 kA interrupting rating at 250V AC. The KTN-R-7 also uses a non-indicating configuration, so buyers can quickly compare key electrical and physical specifications without sorting through unnecessary claims. Before installation, confirm the fuse class, amperage, voltage, interrupting rating, operating characteristic, and dimensions against the requirements of the equipment being serviced.

Where It Works Best

The KTN-R-7 is intended for equipment and circuits requiring a 7A, 250V AC, fast-acting, current-limiting Class R fuse with a 200 kA interrupting rating. Confirm the cartridge configuration and 2.0 x 0.56 x 0.56-inch measurements when matching it to an existing installation. A part number is a useful starting point, but the complete specification tells the real story. Before installation, check amperage, voltage, Class R designation, interrupting rating, fast-acting characteristic, physical size, and fuse-holder compatibility.
