FLSR009 - 9 Amp Fuse Description
FLSR009 - 9 Amp Fuse
When an application calls for a 9-amp Class RK5 time-delay fuse, the FLSR009 provides the electrical characteristics needed for demanding industrial and commercial circuits. This dual-element cartridge fuse is rated for 600VAC and 300VDC and uses a Slo-Blo/time-delay opening characteristic. If you're replacing an existing fuse, don't rely on the 9A rating alone—check the fuse class, voltage, time-delay requirement, interrupting rating, and physical fit against the equipment specifications.
Key Features and Benefits
- 9-amp rating for circuits specifically designed around a 9A protective device.
- Class RK5 construction makes it easier to match the correct fuse class during maintenance or replacement.
- Handles applications up to 600 VAC or 300 VDC.
- Time-delay operation allows the fuse to ride through brief, normal current surges rather than opening unnecessarily.
- Dual-element design delivers the operating characteristics expected from a time-delay fuse.
- High interrupting capability provides added protection in properly rated electrical systems with significant available fault current.
- Industrial cartridge format works with compatible fuse blocks, clips, and holders.

Material Compliance and Certifications
Material-compliance and certification information was not included in the supplied FLSR009 specifications. For applications where a particular certification, regulatory standard, or material-compliance requirement is mandatory, verify the documentation for the exact FLSR009 catalog number before installation.
Where It Works Best
The FLSR009 9A fuse makes the most sense in industrial and commercial electrical equipment that specifically requires a Class RK5, 600V time-delay fuse. It's especially useful in circuits where short-lived startup or inrush currents are normal, and an instantaneous response could lead to unwanted fuse operation.
