KTN-R-3 - 3Amp Fuse

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.

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.
