EEFI RR MKIII

HIGH IMMUNITY EARTH FAULT INDICATOR

The EEFI RR MKIII was developed to meet the  stringent needs of one of our UK clients who demanded a very high degree of immunity from electro-magnetic fields induced into the C/T surrounding the HV cable.  HV Cable Insulation test equipment was prone to trip standard EFIs, so a higher degree of protection was required.  A  replaceable battery makes for easy  change after a predicted 15 year life.
