DEHN Ventil N-PE 50 Spark-Gap Based Protection Module – 951050

The Dehn DEHNventil is a combined surge arrester designed for power technology featuring a network form of TN-S and TT, with 4 poles. It provides lightning impulse current protection (10/350) up to 50kA with a maximum continuous AC voltage of 264V and a nominal AC voltage of 230V. The safety levels are rated at 1.5kV for general safety, L-N, and L-PE scenarios. The follow current extinguishing capacity is 100kA. It is based on a spark-gap protection module for the DEHNventil modular (type 1 according to EN 61643-11).
