Littelfuse FLNR006 6A 250VAC/125VDC Class RK5 Time Delay Fuse

SKU CH-GXQ4-80N83

A 6 A cartridge fuse rated 250 VAC/125 VDC with Class RK5 time-delay protection and a 200,000 A interrupting rating

  • 6 A time-delay protection for motor-start surges
  • 250 VAC / 125 VDC rating suits industrial control circuits
  • 200 kA AC interrupting capacity clears severe faults safely
  • Class RK5 rejection design prevents wrong-fuse installation
  • Cartridge terminal enables quick, tool-free replacement

Littelfuse 6A Class RK5 Fuse

The Littelfuse FLNR006 is a 6 amp time-delay fuse rated for 250 VAC and 125 VDC. It uses a cartridge-style rejection terminal and carries a Class RK5 rating for industrial circuit protection. The dual-element design handles temporary overloads without nuisance opening. Interrupting capacity reaches 200000 amps VAC RMS symmetrical and 20000 amps VDC.

Suits panels needing Class RK5 rejection fit

This fuse fits panels and disconnects that require a Class RK5 rejection-type cartridge. It is not for holders that accept only non-rejection ferrule fuses. Buyers who need a faster-acting or non-time-delay characteristic should look elsewhere. The 6 amp rating also excludes circuits requiring higher or lower current values.

250 VAC / 125 VDC dual voltage rating

The single specification that decides fit is the dual voltage rating of 250 volts AC and 125 volts DC. A circuit exceeding either value cannot use this fuse safely. Verify the system voltage against both figures before installation. The 200000 amp VAC interrupting rating then ensures adequate short-circuit protection.

Questions about this item

How much heat does a 6 A Class RK5 time-delay fuse generate when it runs continuously at full load?

The fuse is rated for 250 VAC and 125 VDC at 6 amps with a 200 000 A VAC interrupting rating; heat rise depends on the surrounding enclosure and ambient temperature, which are not defined by the fuse itself.

What fuse holder or disconnect is required to accept this cartridge-style rejection fuse?

A holder or disconnect rated for Class RK5 rejection-type cartridges with a 9/16-inch diameter and 2-inch length is needed to match the physical dimensions and rejection feature of this fuse.

Will the 200 000 A VAC interrupting rating coordinate with existing panels rated at lower interrupting levels?

The fuse provides a 200 000 A VAC RMS symmetrical interrupting rating; coordination with any specific panel depends on that panel's own interrupting rating and the overall system study.
