FRN-R-70 - 70Amp Fuse

FRN-R-70 - 70Amp Fuse

When you're replacing a fuse, a few small details can make the difference between a match and a part that doesn't belong in the fuse holder. Physical fit is easy to check using the published measurements: 2 inches long, 0.56 inches high, and 0.56 inches wide. In other words, there's no need to work from appearance or amperage alone—the FRN-R-70 gives you specific electrical, connection, and dimensional details to compare with the equipment requirements before installation.

Key Features and Benefits

• 70A Class RK5 with dual-element construction and a non-indicating design.
• Works within its published 250V AC and 125V DC voltage ratings.
• Eaton specifies a 10-second response at 500% of rated current.
• Blade terminals on both ends, with a 2 × 0.56 × 0.56-inch body for checking physical fit.

Material Compliance and Certifications

The manufacturer lists the FRN-R-70 as CE-marked. No other catalog-specific certifications or material-compliance declarations were included in the supplied information. If a job requires a particular approval, confirm that requirement separately before installation.

Where It Works Best

• Equipment calling for a 70A Class RK5 fuse with blade terminals.
• Fuse holders that match the FRN-R-70's dimensions: 2 × 0.56 × 0.56 inches.
• 250V AC circuits where the published 200 kAIC interrupting rating meets circuit requirements.
• 125V DC circuits where the published 20 kAIC interrupting rating is appropriate.
• Maintenance or replacement work where the specified fuse is dual element and non-indicating.
