KTS-R-50 - 50Amp Fuse

KTS-R-50 - 50Amp Fuse

The fastest way to narrow down a replacement fuse is to compare the electrical ratings and physical details together. The Eaton Bussmann KTS-R-50 is a 50A Class RK1 fuse rated at 600V, with a manufacturer-listed interrupt rating of 200 kAIC at 600 Vac. It includes a melamine glass tube and a single element, and the connection is specified as ferrule end x ferrule end. If you're replacing an existing KTS-R-50 or working from equipment documentation that specifies these ratings, the complete specifications below make it easier to verify the match without relying on amperage alone.

Key Features and Benefits

• 50A rating — Gives you a clear starting point when checking the fuse against equipment requirements.
• 600V rating — Helps confirm the required voltage specification before installation.
• Class RK1 classification — Clearly identifies the fuse class for specification and replacement checks.
• Ferrule-to-ferrule connection — Provides an exact connection detail to verify against the existing fuse and equipment.
• Melamine glass tube material — Manufacturer-listed construction information that helps identify the exact KTS-R-50 configuration.
• Single element — The manufacturer specifies one element for this model.
• Non-indicating fuse — The KTS-R-50 is listed as non-indicating.
• CE Marked — Supplies documented compliance details for applications where certification information needs to be checked.

No additional material compliance certification was supplied for this catalog number, so do not assume additional certifications when reviewing the fuse for a particular installation.

Where It Works Best

The KTS-R-50 is a candidate to compare against equipment specifications calling for a 50A, 600V, Class RK1 fuse with a 200 kAIC at 600 Vac interrupt rating. Its ferrule-to-ferrule connection and 5.5 x 1.5 x 1.5-inch dimensions give you additional checkpoints when matching an existing fuse or reviewing maintenance documentation.
