LLNRK300

FUS 250V T/D CLASS RK1 300A | Series: LLNRK
info
Littelfuse LLNRK and LLSRK series POWR-PRO™ fuses provide superior overload and short circuit protection for service entrance, main, feeder and general-purpose branch circuits up to 600 amperes.

LLNRK/LLSRK series fuses can be installed in existing Class H fuse blocks to upgrade systems containing lower interrupting rating Class H one-time or renewable fuses.

  • Extremely current limiting, which reduces damage to circuits and equipment
  • 300 kA interrupting rating
  • Current-limiting performance permits use of less-costly equipment and low resistance reduces power consumption
  • Two-elements, including a thermally reversible spring-loaded thermal overload element, ensures excellent time delay for minimal nuisance opening
