KPV12E is a digitally controlled two-level trip relay monitoring the insulation status of a live AC system, by detecting the displacement of the voltage between the supply system neutral point and PE.
The level of neutral point voltage will depend on the level of earth fault between each line voltage and PE.
-Insulation monitoring and Earth Fault Protection of live non-grounded low or high tension AC supplies
-Direct connection to Neutral in up to 690VAC supply networks
-Triple relay operation gives more flexibility
-Analogue output signal proportional to meter reading (KPV12F)
