The DEHNventil is a modular, multipole combined lightning current and surge arrester that conforms to EN 61643-11 standards. It comprises a base part and pluggable protection modules. The device features RADAX Flow follow current limitation for maximum availability and can protect terminal equipment. Ideal for protecting low-voltage consumer installations against surges and even direct lightning strikes, it can be installed in accordance with the lightning protection zone concept at the boundaries from 0A – 2. Designed for TN-S and TT networks, it has 4 poles and can withstand a lightning impulse of 100kA (10/350). The maximum continuous AC voltage is 264V with a nominal AC voltage of 230V and DC voltage of 255V. The safety voltage level is 1.5kV for L-N, N-PE.
