Usage
Usage as 3rd level ( T3 , fine protection) in 3-level overvoltage protection concept
It decreases overvoltage and reduces overvoltage wave energy caused by induction and switching processes in the connected low voltage network
Installation
Installation into the cable channel and installation boxes or to terminalss of the protected appliance
Protection against the transverse and longitudinal overvoltage (L/N, L/PE, N/PE)
Protective effect provided by a varistor combined with spark gap
Optical and/or acoustical signalisation of operational state
