Dehn Bloc 3 255 H Lightning Current Arrester - 900120
Notice: This product will be discontinued in the future
The DEHNbloc H is a modular single-pole lightning current arrester based on spark-gap technology. It is a type 1 device as per EN 61643-11 with RADAX Flow spark gap technology and high follow current limitation. Designed for the protection of low-voltage consumer installations against surges and direct lightning strikes, it should be installed in accordance with the lightning protection zone concept at boundaries from 0A-1. The device features a maximum continuous voltage AC of 255V, a nominal discharge current of 100kA, and it can accommodate 3 wires excluding earth, with a maximum flexible conductor cross-section size of 35mm² and a maximum rigid conductor size of 50mm². The protection degree is IP20 and it is mountable on a 35mm DIN-rail within a network structure TN-C.
