FRN-R-3 - 3 Amp Fuse

FRN-R-3 - 3 Amp Fuse

For a 3A Class RK5 fuse, the FRN-R-3 provides several details to check before it goes into the fuse holder. It also has an 8-second response time at 500% of rated current, allowing technicians to compare this response characteristic with the equipment's protection requirements. The FRN-R-3 uses ferrule connections at both ends, is non-indicating, and measures 2 inches long by 0.56 inches high by 0.56 inches wide. Add in its 3.48-watt power-loss specification, and you have a fuse with detailed manufacturer data that helps take some of the guesswork out of maintenance and replacement decisions.

Key Features and Benefits

• 3A Class RK5 fuse – The exact amperage and fuse-class combination needed when FRN-R-3 is specified.
• Dual-element construction – provides technicians with another important design characteristic to verify against the existing fuse or equipment documentation.
• Rated 250V AC and 125V DC – Suitable for compatible circuits operating within these published voltage limits.
• 8 seconds at 500% response time – Provides specific manufacturer response data rather than leaving technicians to make assumptions about fuse behavior.
• Ferrule ends – Uses ferrule end × ferrule end connections for installations that require this physical configuration.
• Non-indicating design – Matches equipment specifications calling for the non-indicating FRN-R-3.

Where It Works Best

• FRN-R-3 maintenance and replacement work where the equipment documentation specifies this exact catalog number
• 3A Class RK5 fuse requirements in compatible electrical equipment
• 250V AC circuits operating within the fuse's published voltage and interrupting ratings
• 125V DC circuits within its 20 kAIC DC interrupting rating
• Ferrule-style fuse holders that match the FRN-R-3 connection type and dimensions
• Dual-element fuse specifications where the stated 8-second response at 500% is appropriate for the equipment's protection requirements
