KTN-R-4 - 4Amp Fuse Description
KTN-R-4 - 4Amp Fuse
The useful question isn’t simply, “Is it a 4-amp fuse?” A proper replacement check involves the complete specification. The Eaton Bussmann KTN-R-4 is a 4A, 250V Class RK1 fuse with a single-element configuration and a non-indicating design. If your required catalog number is KTN-R-4, checking the 4A rating, 250V rating, RK1 class, dimensions, and other listed characteristics together is a much better approach than choosing a replacement based on amperage alone.
Key Features and Benefits
- 4A amperage rating — clearly identifies the electrical rating for specification matching.
- 250V rating gives buyers another essential value to verify against equipment requirements.
- Class RK1 fuse — the manufacturer identifies the KTN-R-4 specifically within this fuse class.
- Single-element construction provides a clear physical specification for replacement verification.
- Non-indicating configuration matches applications where this fuse type is specified.
- Catalog number KTN-R-4 helps distinguish this 4A model from other amperage ratings within the KTN-R series.

Where It Works Best
The Eaton Bussmann KTN-R-4 is appropriate to evaluate when equipment documentation specifically calls for a 4A, 250V Class RK1 fuse and the remaining published specifications also match. Its 2-inch length, 0.56-inch height and width, single-element configuration, and non-indicating format provide additional checkpoints when comparing it with an existing fuse or maintenance documentation.
