The coupling network type CDN 11 3 enables hybrid surge pulses to be coupled into 3- phase equipment, systems and installations. The coupler precisely matches the surge generators type NSG 650 and NSG 651 both electrically and mechanically. Permanently mounted high voltage cables with touch-proof connectors link the couplerwith either of the generators which also supply the power for the associated safety circuit.
