| Item Description | Overvoltage protection / overvoltage protection for public lighting type 1+2 (b+c) according to EN 61643-11:2012 / po ii LED 230V/30KA - overvoltage protection for public lighting type 1+2 (b+c) according to EN 61643-11:2012. Usage for LED lights as 1ND and 2RD level ( T1 coarse and T2 medium 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 into the LED lamps. Protection against the transverse and longitudinal overvoltage (L/N, L/PE, N/PE). Protective effect provided by a VARISTOR combined with spark gap. Optical signalization of operational state.po ii LED 230V/30KA - overvoltage protection for public lighting type 1+2 (b+c). Installation into the LED lamps.
