KTN-R-350 - 350Amp Fuse

KTN-R-350 - 350Amp Fuse

Electrical replacement work leaves little room for assumptions, especially when amperage, voltage, fuse class, and interrupt ratings all matter. The Eaton Bussmann KTN-R-350 is a 350A Class RK1 fuse rated for 250 Vac and 250 Vdc. Whether you're identifying a replacement during maintenance or checking a fuse against equipment documentation, the KTN-R-350 catalog number, 350A rating, AC/DC voltage ratings, Class RK1 designation, interrupt ratings, and dimensions give you clear specifications to compare before installation.

Key Features and Benefits

• 350A amperage rating — a key specification for confirming the required fuse.
• 250 Vac and 250 Vdc ratings let you check voltage requirements for either listed AC or DC use.
• Class RK1 designation makes fuse-class verification straightforward.
• Single-element configuration is clearly identified in the manufacturer specifications.
• Non-indicating fuse configuration.

Material Compliance and Certifications

The supplied manufacturer specifications for the KTN-R-350 list compliance as: Not Applicable. The supplied product data includes no material specifications or additional certification information, so none is assumed here. This keeps the product description tied to the documented specifications rather than applying characteristics from other KTN-R fuse models to this catalog number.

Where It Works Best

The Eaton Bussmann KTN-R-350 fuse is best evaluated for electrical equipment whose documented requirements call for a 350A, Class RK1 fuse rated at 250 Vac or 250 Vdc, while also meeting the applicable interrupt-rating requirements. For AC specifications, the manufacturer lists 200 kAIC at 250 Vac; for DC specifications, the listed value is 100 kAIC at 250 Vdc.
