KTN-R-200 - 200Amp Fuse

KTN-R-200 - 200Amp Fuse

When equipment specifications call for a 200A Class RK1 fuse, the full set of ratings matters—not just the amp number. The Eaton Bussmann KTN-R-200 is rated at 200A and 250 Vac/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 fuse element, blade-end connections, and 70/30 brass end caps. For replacement work, checking the catalog number, fuse class, amperage, AC or DC voltage, interrupt rating, connection style, and dimensions together is a straightforward way to confirm you have the correct specification.

Where It Works Best

The Eaton Bussmann KTN-R-200 is a replacement option to evaluate when the equipment documentation specifies a 200A Class RK1 fuse rated for 250 Vac or 250 Vdc and the applicable interrupt rating matches the system requirements. For AC specifications, the listed interrupt rating is 200 kAIC at 250 Vac; for DC specifications, it is 100 kAIC at 250 Vdc.
