FRN-R-35 - 35 Amp Fuse

FRN-R-35 - 35 Amp Fuse

Working with an FRN-R-35 and want to make sure the replacement checks all the right boxes? Start with the details that matter. This 35-amp Class RK5 dual-element fuse is rated for 250V AC and 125V DC, with ferrule connections at both ends and a non-indicating configuration. Its published interrupting ratings are 200 kAIC at 250V AC and 20 kAIC at 125V DC, and the manufacturer specifies a 10-second response time at 500% of rated current. Put those specifications together, and you have a well-documented fuse that electricians and maintenance teams can confidently compare with the equipment and circuit requirements before installation.

Key Features and Benefits

• 35A, Class RK5 configuration – The FRN-R-35 combines a 35-amp rating with the specified Class RK5 fuse classification.
• Dual-element construction for equipment requiring this fuse design.
• AC and DC rated – 250V AC and 125V DC ratings give you published limits to check against the circuit.
• 10 seconds at 500% response time – A specific manufacturer-published response characteristic rather than a vague performance description.
• Ferrule ends on both sides make the connection style simple to identify during replacement.
• Non-indicating configuration – An important detail when the equipment or existing fuse calls for the non-indicating FRN-R-35.

Where It Works Best

• Replacing an existing FRN-R-35 fuse when the equipment specifications and circuit requirements agree with the ratings shown above.
• 35A Class RK5 fuse positions calling for dual-element construction.
• Ferrule-style fuse installations that accommodate a 3 × 0.81 × 0.81-inch fuse.
• Equipment calling for a non-indicating FRN-R fuse.
• Maintenance situations where technicians need to verify the fuse's 10-second response at 500% against the specified protection requirements.
