FRN-R-25 - 25 Amp Fuse

FRN-R-25 - 25 Amp Fuse

The FRN-R-25 fuse is one where every detail counts. While it’s rated for 25 amps, there’s much more to it than just that. This Class RK5 dual-element fuse operates at 250V AC and 125V DC, featuring ferrule connections on both ends, all packed into a compact 2-inch body.

What might really catch your eye are its impressive interrupting ratings: it can handle up to 200 kAIC at 250V AC and 20 kAIC at 125V DC. Plus, it has an 8-second response time at 500% of its rated current. For electricians and maintenance teams, these specifications are essential to ensure safety and performance before the fuse is activated. When you're dealing with equipment that relies on this fuse, having these concrete numbers at your fingertips makes all the difference.

Key Features and Benefits

• 25A Class RK5 fuse – The FRN-R-25 combines a 25-amp rating with Class RK5 construction.
• Dual-element construction – Matches equipment specifications calling for this element configuration.
• 250V AC / 125V DC rated – Can be used in compatible AC or DC circuits within its published ratings.
• 8-second response at 500% – Gives you a specific response characteristic to compare with the requirements of the circuit.
• Ferrule connections – Ferrule ends on both sides provide a readily identifiable physical configuration.
• Non-indicating – This is the non-indicating version of the FRN-R-25.
