FLSR006 - 6 Amp Fuse

FLSR006 - 6 Amp Fuse

When your circuit sees a brief startup surge, you don’t necessarily want the fuse to open immediately. That’s where the FLSR006 6A Class RK5 time-delay fuse comes in. This industrial cartridge fuse uses a dual-element, time-delay design that allows it to tolerate normal short-duration inrush current while still providing overcurrent protection when it’s needed. Rated at 6 amps and with a maximum voltage of 600VAC or 300VDC, the FLSR006 is designed for demanding electrical applications where the correct fuse characteristics matter. It can be installed in a compatible fuse block, clip, or holder, including the specified LFR60030 Series holder family.

Key Features and Benefits

• 6 amp continuous rating for circuits requiring 6A overcurrent protection.
• Class RK5 configuration for equipment designed around this specific fuse class.
• Handles applications rated up to 600 VAC and 300 VDC.
• Dual-element, time-delay operation accommodates brief, normal current surges without opening prematurely.
• Slo-Blo/time-lag characteristics can help reduce nuisance fuse operation in appropriate applications.
• Industrial cartridge construction fits compatible fuse blocks, clips, and holders.
• The manufacturer's specifications list compatibility with the LFR60030 Series holder.
• Non-indicating design for applications that do not require a visual blown-fuse indicator.

Material Compliance and Certifications

The FLSR006 is identified as a Class RK5 fuse in the supplied manufacturer specifications. Specific UL, CSA, RoHS, REACH, or other material compliance and certification details were not included in the provided product information. When a particular certification or material declaration is required for a project, confirm it against the current documentation for the exact FLSR006 catalog number.

Where It Works Best

The FLSR006 makes sense in industrial circuits where temporary inrush current is expected, but dependable overcurrent protection remains essential. Its time-delay characteristics can be useful with compatible motors, transformers, machinery, control equipment, and other industrial electrical loads that may briefly pull additional current during startup.

It’s also a natural fit for maintenance and replacement work when the equipment specifically calls for a 6A, 600V Class RK5 time-delay cartridge fuse. Before replacing an existing fuse, match the amp rating, voltage, fuse class, time-delay characteristics, interrupting capacity, physical configuration, and holder requirements to the equipment specifications.
