KTN-R-300 - 300Amp Fuse

KTN-R-300 - 300Amp Fuse

Electrical replacement work leaves little room for assumptions. The Eaton Bussmann KTN-R-300 provides a clear specification set to check against your equipment requirements: 300 amps, Class RK1, and 250V AC/DC. Just as important, its interrupt ratings are 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc, details that deserve attention when confirming a replacement fuse.

Key Features and Benefits

• 300A amperage rating — clearly defined for equipment requiring a 300-amp fuse.
• 250 Vac / 250 Vdc rating allows you to check the electrical specification for either listed voltage type.
• Class RK1 designation makes fuse-class verification straightforward.
• Single-element construction — the manufacturer specifies one fuse element.
• Non-indicating design with no visual fuse-status indicator listed.

Where It Works Best

The Eaton Bussmann KTN-R-300 fuse is best evaluated for equipment whose documentation specifically calls for a 300A Class RK1 fuse rated at 250 Vac or 250 Vdc, along with the applicable interrupt rating. Physical dimensions matter too, especially when you're replacing an existing fuse and need to confirm more than the amperage printed on its label.
