FRN-R-5 - 5 Amp Fuse

FRN-R-5 - 5 Amp Fuse

The FRN-R-5 is a 5-amp Class RK5 fuse with a longer, 3-inch ferrule-ended body, so physical size is an important detail when you’re checking it for an existing fuse position. It uses dual-element construction, is non-indicating, and has a manufacturer-specified response of 8 seconds at 500% of rated current. The body measures 3 × 0.81 × 0.81 inches and weighs 0.1 lb. Put those details together, and you have a very specific FRN-R configuration—useful when the job calls for the right amperage, fuse class, voltage rating, connection style, and physical fit rather than a close-looking substitute.

Key Features and Benefits

• 5A Class RK5 fuse with dual-element construction.
• Rated 250V AC and 125V DC, covering the voltage specifications published for this catalog number.
• 8-second response at 500% of rated current, giving you an exact manufacturer-published response specification to work from.
• Ferrule end × ferrule end connection with a 3-inch body.
• Non-indicating configuration—an important detail when replacing a fuse in equipment that specifies this version.

Material Compliance and Certifications

The manufacturer information supplied for the FRN-R-5 lists the fuse as CE Marked. No other catalog-specific certifications or material-compliance designations were included in the provided specifications.

Where It Works Best

• Fuse positions calling for an FRN-R-5 or the same complete set of electrical and physical specifications.
• 5A Class RK5 fuse holders that accept ferrule ends and the 3 × 0.81 × 0.81-inch body size.
• 250V AC circuits where a 200 kAIC at 250V AC interrupting rating meets the circuit requirements.
• Installations specifying dual-element, non-indicating construction and the stated 8-second-at-500% response characteristic.
