KTN-R-3 - 3Amp Fuse Description
KTN-R-3 - 3Amp Fuse
Fuse replacement gets easier when you have the exact specifications in front of you. The Eaton Bussmann KTN-R-3 is a 3A, 250V Class RK1 fuse measuring 2 inches long, with a 0.56-inch height and width. If you're matching an existing KTN-R-3, don't stop after finding "3A" on the specification sheet. Also check the 250V rating, RK1 class, ferrule connection, dimensions, and construction. Those details give you a much clearer way to confirm you're looking at the right fuse for the equipment.
Key Features and Benefits
- 3A rating: Matches equipment specifications calling for a 3-amp fuse.
- 250V rating: An important value to confirm against the equipment requirements before installation.
- Class RK1: Clearly identifies the fuse class for specification and replacement checks.
- Ferrule ends: Uses a ferrule-end-to-ferrule-end connection.
- Single element: The KTN-R-3 lists one fuse element.
- Melamine glass tube: Identifies the specified body material.
- 70/30 brass end cap: The manufacturer lists this as a special feature.
- Non-indicating: This model has no integral fuse-status indicator.

Where It Works Best
Consider the Eaton Bussmann KTN-R-3 when the equipment documentation specifically calls for a 3A, 250V Class RK1 fuse and the remaining specifications match. Its ferrule-to-ferrule connection, single-element construction, non-indicating configuration, and physical dimensions give you several points to check against the fuse being replaced.
