Short Description

JLS series fuses provide space-saving, Fast-Acting overload and short circuit protection for non-inductive loads. When used for motors or other inductive loads, the ampere rating of JLS series fuses must be increased to prevent nuisance opening on inrush currents. In such applications, JLS fuses may provide only short circuit protection.

Features

  • Space saving - JLS fuse characteristics are similar to KLNR/KLSR Fast-Acting Class RK1, but they are much smaller
  • Extremely current limiting - stops damaging short circuit current faster than any mechanical protective device
  • Fast-Acting - provides Fast-Acting protection to equipment such as variable speed drives, rectifiers and other equipment containing surge-sensitive components
  • Longer equipment life - current-limiting design reduces damage to equipment caused by heating and magnetic effects of short circuit currents
  • Economical - extremely current-limiting design often permits use of readily available, less costly equipment
  • Easy to use
  • North American style
  • 200 kA at 600 VAC RMS symmetrical
