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 on 35 mm DIN rail
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 remote signalling of operation state
