FRN-R-80 - 80Amp Fuse

FRN-R-80 - 80Amp Fuse

When you're tracking down an FRN-R-80, getting the details right matters. This 80A Class RK5 fuse uses dual-element construction, blade terminals at both ends, and a non-indicating design. Physically, the fuse measures 5.88 inches long, 1 inch high, and 1 inch wide. That gives you a solid set of electrical and dimensional details to compare with the fuse holder and circuit requirements before installation.

Key Features and Benefits

• 80A Class RK5 rating with dual-element construction.
• Handles applications within its published 250V AC and 125V DC ratings.
• Eaton specifies a 10-second response at 500% of rated current.
• Blade end × blade end construction and a non-indicating design.
• Measures 5.88 × 1 × 1 in., an important check when confirming the intended fuse position.

Where a project calls for a particular certification or compliance document, verify that requirement separately before installation.

Where It Works Best

• Existing electrical equipment calling for an FRN-R-80 80A Class RK5 fuse.
• Class RK5 fuse positions requiring blade-to-blade connections and the stated dimensions of 5.88 × 1 × 1 in.
• 250V AC circuits where a 200 kAIC at 250V AC interrupting rating satisfies the circuit requirements.
• 125V DC circuits where the 20 kAIC at 125V DC rating and remaining FRN-R-80 specifications are appropriate.
• Maintenance work where the fuse class, amperage, voltage, connection style, dimensions, and interrupting rating have all been confirmed.
