Usage
Usage as 3rd level ( T3 , fine protection) in 3-level protection concept against overvoltage
It decreases overvoltage and reduces overvoltage wave energy caused by induction and switching processes in the connected low voltage network
Installation
Installation into the installation boxes
Protection against the transverse and longitudinal overvoltage (L/N, L/PE, N/PE)
Protective effect provided by a varistor combined with spark gap
Optical signalisation state of overvoltage protection:
– basic version – a green indicator signals OK function
– inverse version (I) – a red indicator signals OUT / faulty
