KTN-R-500 - 500Amp Fuse

KTN-R-500 - 500Amp Fuse

One part number can carry a lot of important information, and with the Eaton Bussmann KTN-R-500, those details are worth checking carefully. This 500A Class RK1 fuse is rated for 250 Vac and 250 Vdc, with an interrupt rating of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. The manufacturer lists a single-element configuration, blade-end-to-blade-end connection, and melamine glass tube construction. For maintenance teams, electricians, and electrical buyers comparing a replacement against your equipment specification, these clearly defined electrical and physical characteristics make it easier to check the entire fuse specification rather than relying on amperage alone.

Key Features and Benefits

• 500A amperage rating gives buyers a clear starting point when matching the fuse to equipment documentation.
• Rated for both 250 Vac and 250 Vdc.
• Class RK1 classification helps distinguish the KTN-R-500 when checking the required fuse class.
• The blade-end-to-blade-end connection provides an important physical detail to compare with the existing installation.
• Uses a single-element configuration.
• The manufacturer lists melamine glass tube as the material.
• A 70/30 brass end cap is listed as a special feature.

Where It Works Best

The Eaton Bussmann KTN-R-500 500A fuse is a model to evaluate when the equipment documentation specifies a 500A Class RK1 fuse rated for 250 Vac or 250 Vdc and the required interrupt rating matches 200 kAIC at 250 Vac or 100 kAIC at 250 Vdc, as applicable. The electrical ratings are only part of the check. Buyers should also compare the blade-end-to-blade-end connection, single-element configuration, and physical dimensions with the equipment requirements.
