KTS-R-125 - 125Amp Fuse

KTS-R-125 - 125Amp Fuse

For maintenance teams working from an equipment list or existing part number, the Eaton Bussmann KTS-R-125 is easy to identify by its 125A, 600V, and Class RK1 ratings. Just as important, the manufacturer lists an interrupt rating of 200 kAIC at 600 Vac, giving buyers another critical specification to verify before installation. This single-element fuse uses a melamine glass tube, a blade-end-to-blade-end connection, and a 70/30 brass end cap listed as a special feature. For replacement work, start with catalog number KTS-R-125, then compare the amperage, voltage, fuse class, interrupt rating, connection, and dimensions with your equipment requirements. That full-specification approach is far more useful than choosing a fuse based on amperage alone.

Key Features and Benefits

• 125A amperage rating: Clearly identifies the current rating for comparison with the equipment specification.
• 600V rating: Supplies an essential voltage specification to verify before installation.
• Class RK1: Identifies the fuse class for accurate comparison with the required equipment specifications.
• Blade end x blade end: The connection configuration is explicitly listed, helping technicians verify the physical setup rather than relying on appearance alone.
• Melamine glass tube: Manufacturer-specified construction material provides another useful product-identification detail.
• Single-element configuration: The KTS-R-125 is specified with one element.
• 70/30 brass end cap: The manufacturer lists this as a special feature.
• Non-indicating: The fuse is listed as non-indicating.

Material Compliance and Certifications

The KTS-R-125 is CE marked according to the supplied manufacturer specifications. Its construction material is listed as a melamine glass tube, while a 70/30 brass end cap appears under special features. The supplied data provided no additional material-compliance standards or certifications, so none are assumed here.

Where It Works Best

Compare the KTS-R-125 125A Class RK1 fuse with equipment documentation specifying a 125A, 600V Class RK1 fuse and a 200 kAIC interrupt rating at 600 Vac. The listed blade-end-to-blade-end connection and 9.63 x 1.5 x 1.5-inch dimensions also give technicians concrete physical specifications to check when replacing an existing fuse.
