FLNR007 - 7 Amp Fuse

FLNR007 - 7 Amp Fuse

When your circuit requires a 7-amp Class RK5 fuse with time-delay performance, the FLNR007 is built for the job. This dual-element industrial cartridge fuse is rated for 250VAC and 125VDC and uses a Slo-Blo/time-delay opening characteristic. That delay matters in applications where equipment can draw a brief current surge during startup. Instead of reacting immediately to a normal, short-lived inrush, the FLNR007 is designed to tolerate temporary surges while still providing overcurrent protection during an actual overload or short circuit. It also offers substantial interrupting capability—up to 300 kA AC and 20 kA DC under the specified conditions.

Key Features and Benefits

• 7A current rating – Designed for applications requiring a 7-amp fuse.
• Time-delay performance – Helps accommodate brief startup and inrush currents that are normal for certain types of electrical equipment.
• Dual-element construction – Combines time-delay operation with overcurrent protection in a single cartridge fuse.
• 250VAC / 125VDC ratings – Suitable for compatible AC and DC circuits within the stated ratings.
• High interrupting capability – Rated up to 300 kA AC and 20 kA DC under specified conditions.
• Class RK5 design – Made for electrical systems requiring this specific fuse class.
• Industrial cartridge format – Fits compatible fuse blocks, clips, and holders.

Material Compliance and Certifications

Specific material-compliance declarations and individual certification details were not included in the supplied FLNR007 product information. If your installation requires a particular certification, environmental declaration, or regulatory compliance standard, confirm those requirements against the documentation for the exact FLNR007 catalog number before installation.

Where It Works Best

The FLNR007 Class RK5 fuse makes the most sense in compatible industrial and commercial circuits where temporary current surges are expected during normal operation. Its time-delay characteristic allows it to handle brief inrush conditions without opening unnecessarily, while the dual-element design continues to protect against sustained overloads and short circuits.

It’s also a practical replacement for existing electrical equipment that specifically requires a 7-amp, 250 VAC Class RK5 time-delay cartridge fuse. Before replacing any fuse, check more than the amperage printed on the label. The required fuse class, voltage rating, interrupting capacity, time-delay characteristics, and equipment specifications should all match the application.
