The company's history of success started on January 21, 1910, when the master electrician Hans Dehn registered his electrical installation business in Nuremberg. Now, more than 110 years later, the family-owned company, which is managed by the fourth generation, has about 2,000 employees worldwide.

The industrial sector of the DEHNgroup, the parent company DEHN SE + Co KG and its international subsidiaries, are globally active in the fields of surge protection, lightning protection, earthing and safety equipment.

The electrical installation business, DEHN INSTATEC, with branches in Nuremberg, Neumarkt, Hermsdorf and Hamburg, continues the legacy of the founder Hans Dehn.
