FRN-R-8 - 8 Amp Fuse

FRN-R-8 - 8 Amp Fuse

The FRN-R-8 keeps the identification fairly simple: it's an 8A Class RK5 dual-element fuse with ferrule terminals at both ends and a non-indicating design. Physically, the fuse measures 2 × 0.81 × 0.81 inches, so there are clear dimensions to check against your existing fuse holder. When FRN-R-8 is the catalog number called for, confirming the fuse class, voltage, connection style, dimensions, and interrupting rating helps make sure the replacement matches the equipment requirements.

Key Features and Benefits

• 8A Class RK5 rating with dual-element construction and a non-indicating design.
• Handles applications rated up to 250V AC or 125V DC, within the manufacturer's published specifications.
• Eaton specifies an 8-second response at 500% of rated current.
• Ferrule ends on both sides, and a 2 × 0.81 × 0.81 in body gives you the connection and dimensional details needed for fit verification.

Material Compliance and Certifications

The manufacturer lists the FRN-R-8 as CE-marked. No other catalog-specific certifications or material-compliance declarations were included in the supplied product data. If a job requires an additional approval or material declaration, verify that requirement separately before installation.

Where It Works Best

• Equipment calling for an 8A Class RK5 fuse with dual-element construction.
• Fuse holders that accept a ferrule end × ferrule end connection and the FRN-R-8's published dimensions.
• 250V AC circuits where a 200 kAIC interrupting rating satisfies the circuit requirements.
• 125V DC circuits where the specified 20 kAIC interrupting rating is appropriate.
• Maintenance work where the specified replacement is FRN-R-8 and the equipment requirements match its published ratings.
