KTS-R-300 - 300 Amp Fuse

KTS-R-300 - 300 Amp Fuse

The Eaton Bussmann KTS-R-300 is a 300A Class RK1 fuse rated at 600V, giving maintenance teams and electrical buyers clear specifications to check when replacing an existing fuse. Its 200 kAIC interrupt rating at 600 VAC is an important part of that comparison, along with the blade-end-to-blade-end connection and physical dimensions. Rather than choosing a replacement from amperage alone, compare the catalog number, voltage, class, interrupt rating, connection style, and dimensions with your equipment documentation. That gives you a much clearer picture of whether the KTS-R-300 matches the application.

Key Features and Benefits

Material Compliance and Certifications

The KTS-R-300 is CE Marked, according to the supplied manufacturer specifications. Its listed material is melamine glass tube. The source data provided no additional material-compliance certifications, so assume none and do not add any to the product listing.

Where It Works Best

The Eaton Bussmann KTS-R-300 is for equipment documentation specifying a 300A, 600V Class RK1 fuse with a 200 kAIC interrupt rating at 600 Vac. It is especially straightforward to evaluate for replacement work because the manufacturer supplies both the electrical ratings and the physical measurements needed for a side-by-side comparison.

Before installation, confirm the KTS-R-300 catalog number, 300A rating, 600V rating, Class RK1 classification, interrupt rating, blade-end-to-blade-end connection, and 11.63 x 2 x 2-inch dimensions against the existing fuse and equipment requirements. Those details matter more than simply finding another fuse labeled “300A.”
