Link Box

Programmable Earth Fault or Overcurrent and Earth Fault Indication
with comms option

The Link Box Fault Passage Indicator (FPI) is deployed on the links of an LV Link box. Once deployed the Link Box FPIs provide fault location when a fault occurs, by indicating on which leg of the Link Box the fault has occurred. There is no need to remove links or fuses, simply drop the Link Box FPIs over the Links and they are ready to go.
