The DEHNvenCI is a single-pole combined lightning current and surge arrester of types 1 and 2, in accordance with EN 61643-11. It is fitted with an integrated back-up fuse and features RADAX FLOW follow current limitation for maximum availability. This device is capable of protecting terminal equipment and safeguards low-voltage consumer installations against surges and direct lightning strikes. It is designed to be installed in compliance with the lightning protection zone concept at the boundaries from 0A – 2. The arrester has a nominal voltage of 230V and a maximum continuous AC voltage of 255V. Its design is such that it fits on a DIN rail and is 4 TE in size.
