FRN-R-9 - 9 Amp Fuse

FRN-R-9 - 9 Amp Fuse

When the FRN-R-9 is the fuse you need to match, there are a few details you'll want to verify before it goes into the equipment. This 9A Class RK5 fuse uses dual-element construction, has ferrule terminals at both ends, and is non-indicating. Physically, the fuse measures 2 × 0.56 × 0.56 inches. That combination of electrical ratings, fuse class, connection style, and dimensions gives you the information needed to confirm compatibility with the intended fuse position rather than relying on appearance alone.

Key Features and Benefits

• 9A Class RK5 fuse with dual-element construction.
• Handles applications rated up to 250V AC or 125V DC, within its published specifications.
• Response is specified at 8 seconds at 500% of rated current.
• Ferrule end × ferrule end construction, with a non-indicating body measuring 2 × 0.56 × 0.56 in.

Material Compliance and Certifications

The FRN-R-9 is CE-marked, according to the supplied manufacturer data. No additional catalog-level certifications or material-compliance declarations were provided. For installations that require a particular approval or compliance document, confirm that requirement separately.

Where It Works Best

• Equipment that specifically calls for the FRN-R-9 9A fuse.
• Class RK5 fuse positions requiring ferrule-end connections and the stated dimensions.
• 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 published specifications are appropriate.
• Replacement and maintenance work where the original fuse's class, amperage, voltage, connection, and physical dimensions have been confirmed.
