FLNR025 - 25 Amp Fuse

FLNR025 - 25 Amp Fuse

When your circuit has to handle normal startup current without sacrificing dependable overcurrent protection, the FLNR025 25 Amp Class RK5 fuse is built for the job. This dual-element industrial cartridge fuse has a 25A continuous current rating and is rated for applications up to 250 VAC or 125 VDC. Its Slo-Blo/time-delay opening characteristic allows it to ride through brief current surges that can occur during equipment startup, while still protecting in the event of an overload or short circuit. The FLNR025 also offers substantial fault-interruption capability, with a manufacturer-specified interrupting rating of up to 300 kA AC and 20 kA DC.

Key Features and Benefits

• 25A current rating: Designed for circuits requiring a 25-amp Class RK5 fuse.
• Time-delay performance: Helps prevent unnecessary fuse operation during brief, normal inrush-current conditions.
• Dual-element design: Combines time-delay characteristics with overcurrent protection.
• 250 VAC / 125 VDC ratings: Suitable for properly rated AC and DC electrical systems.
• Industrial cartridge format: Fits compatible fuse blocks, clips, and holders.
• Class RK5 construction: A practical replacement choice when equipment specifications call for this particular fuse class.
• Non-indicating design: Intended for applications where a built-in visual blown-fuse indicator isn't required.

Material Compliance and Certifications

The manufacturer identifies the FLNR025 as a Class RK5 dual-element fuse and specifies its electrical ratings, time-delay operation, and interrupting capabilities.

Where It Works Best

The FLNR025 makes sense in industrial and commercial electrical systems where brief current spikes are part of normal operation. Equipment startup is a good example: rather than reacting to every short-lived surge, its time-delay characteristic is designed to accommodate temporary inrush current while maintaining overcurrent protection for the circuit.

That makes this 25-amp Class RK5 fuse a good fit for properly specified applications involving motors, transformers, industrial machinery, control equipment, and similar electrical loads that require time-delay protection.
