KTN-R-40 - 40Amp Fuse

KTN-R-40 - 40Amp Fuse

When equipment specifications call for a 40A Class RK1 fuse, the details beyond amperage deserve just as much attention. The Eaton Bussmann KTN-R-40 is rated at 40 amps and 250 volts, with a single-element configuration, melamine glass tube, and ferrule-to-ferrule connection. Whether you're checking a replacement during scheduled maintenance or identifying a fuse from an equipment list, matching the catalog number, electrical ratings, fuse class, connection, and dimensions helps remove uncertainty.

Key Features and Benefits

• 40A amperage rating — an essential specification when matching the fuse to equipment requirements.
• 250V voltage rating gives technicians another critical value to verify before replacement.
• Class RK1 classification clearly identifies the manufacturer's stated fuse class.
• Single-element configuration provides another useful specification for side-by-side product verification.
• The ferrule-to-ferrule connection makes the connection style easy to confirm against the existing installation.
• Melamine glass tube construction is the manufacturer-specified material for this model.
• 70/30 brass end cap is listed as a special feature.
• Check the non-indicating configuration when matching the characteristics of the fuse being replaced.

Where It Works Best

Consider the KTN-R-40 fuse when equipment documentation specifies a 40A, 250V Class RK1 fuse and the remaining physical characteristics match the installation. In particular, confirm the 3-inch length, 0.81-inch height and width, ferrule-to-ferrule connection, single-element configuration, and non-indicating format against the equipment requirements.
