Geopolitical tensions, growing demands for energy security, and the accelerated global expansion of renewable energy are reshaping the energy sector as never before. The transition to a resilient, decentralised and largely electrified power supply is inevitable. From June 23 to 25, at The smarter E Europe 2026 in Munich, DEHN will be demonstrating how to safely navigate this development with a 360° approach to comprehensive lightning and surge protection solutions for applications increasingly characterised by direct current.
The megatrends of our time act as a catalyst for advancing global electrification: from the expansion of renewable energies and the modernisation of buildings to a growing demand for data centres, which require increasingly powerful infrastructure. Protection concepts that consider lightning and surge protection alongside occupational safety are essential for seamless operation. At Light + Building 2026 in Frankfurt, DEHN will present a 360° approach that combines holistic solutions in the form of consulting, planning, engineering services and bespoke analogue and digital products. From 8 to 13 March 2026, visitors to the exhibition can discover their ideal protection solution at booth B90 in hall 12.0.

Digitalisation, networked systems and automation are rendering modern electrical installations increasingly complex. The rising proportion of renewable energy sources in the grid is changing its parameters in terms of short-circuit behaviour and protection technology, creating fresh challenges for planners and installers. With the new DEHNventil ACI M TNS 264 FM, DEHN is the first supplier to launch an arrester for Type 1 applications based on its ACI (Advanced Circuit Interruption) technology. The specialist for lightning and surge protection and safety equipment is thus expanding its established ACI portfolio for Type 2 arresters to create a comprehensive product family which fulfils the increasingly stringent requirements on surge protection in the field of electrical installation and planning.
Retrofitting earthing systems in existing buildings poses challenges for owners and specialised companies. A functioning earthing system is essential, especially when it comes to renovations, energy modernisations or the installation of photovoltaic systems, wall boxes and heat pumps. However, many existing buildings lack proof of standard-compliant earthing or use outdated systems such as water pipe net-works. In addition, limited space, sealed surfaces and difficulty accessing the soil often make conventional retrofitting a complex and costly undertaking. With the new D18014 earth rod set, DEHN provides a practical solution specially developed for the requirements of renovating existing buildings.
Long connection cables, which cause inductive voltage drops in switchgear cabinets, often pose a challenge for installers. DEHN solves this problem with an innovative advancement of its proven connection technologies. With the new double screw technology in the Type 2 + 3 surge protective device series DEHNguard MD, the company is once again confirming its pioneering role. This technology complements the existing screw and push-in connection terminal and enables the wiring of different types of conductors. The feed-through wiring option also offers even greater flexibility in terms of electromagnetic compatibility (EMC) for applications with a nominal current of up to 63 A.
Sustainability is one of the main pillars of DEHN's corporate strategy. In a brief update, the company highlights key figures, progress made, and strategic priorities; thus, providing transparent information on the status of its sustainable development.

Safety in the workplace is a key concern for energy suppliers just as it is in modern industry. Voltage alarms / electrical field detectors play an important role. The DEHNsense EFD electrical field detector warns of the dangers of electric current visually, acoustically and by vibration when it detects a critical AC voltage, thus alerting the user in good time before entering the danger zone. As an additional measure to the 5 safety rules, the detector significantly increases safety when working on electrical systems. Accidents caused by human error – such as when an electrically skilled person accidentally approaches the wrong energised switchgear installation – can be avoided. The DEHNsense EFD can be used in indoor installations and outdoors even in wet weather (IP degree of protection 65). The detector is easy to operate and can be worn variably on the wrist over the glove or on the helmet.

DEHN, a leading company in the field of lightning and surge protection, has further expanded its successful collaboration with the non-profit organisation AfB gGmbH, ‘Work for people with disabilities.’ This cooperation between DEHN and AfB to recycle and reuse decommissioned IT equipment was recently awarded a certificate for socio-ecological impact with IT hardware.
Over the last year, DEHN handed over 555 decommissioned IT devices such as PCs, notebooks, monitors, printers and tablets to the largest non-profit IT company in Europe, AfB. Around 48 per cent of the 660-strong workforce at AfB are disabled, some of them severely.
AfB takes care of the whole refurbishing process, from collecting the devices to classifying and remarketing them. Often the hardware is still good enough for private use, but no longer for business purposes. The high rate of reuse is impressive: more than 72 percent of the devices collected were resold. In the case of tablets, the figure was as high as 98 percent. Any defective hardware is salvaged for spare parts or recycled for its raw materials.
This partnership allows DEHN to protect the environment and conserves resources and, at the same time, back a socially committed company. To date, the cooperation has saved 119,906 kWh of energy, 452,138 litres of water and 45,405 kg of CO₂ equivalents.
The importance of decentralised energy generation through PV systems will continue to increase. Safe operation of these systems is therefore essential for a stable energy supply. However, solar power cannot be generated without an inverter, the central component of a solar power system. But the inverter could be disrupted or even fail completely if, for example, subjected to the force of a lightning strike. Surge arresters (SPDs) for protecting the DC side of inverters are therefore an important component of protection concepts. DEHNguard MP YPV is the new surge protective device from DEHN for protecting photovoltaic systems on residential buildings. This Type 2 DC surge arrester expands the product range with its practical push-in double terminal. As a prewired, modular complete unit for photovoltaic systems, consisting of a base part and plug-in protection modules, it offers advantages for planning, installation and maintenance.
For many years, DEHN has been deeply concerned with the issue of sustainability, successfully integrating a wide range of measures at all levels and in all areas of the company. The family-owned company reconciles ecological, social and economic considerations with legal requirements and societal demands. “It is our corporate obligation to take responsibility for our own actions. We want to do our bit and hand over a planet on which life is worth living to future generations.” says Dr Philipp Dehn (CEO of DEHN SE). “For us, this means: economic growth must go hand in hand with the protection of resources and people. Joining the UN Global Compact is the next step towards a consistently sustainable corporate focus."
More frequent extreme weather events and increasingly interconnected electronic devices pose a greater risk of damage due to lightning strikes and surges. Appropriate protective measures in compliance with current standards and regulations are required to protect people, buildings, systems, as well as modern energy generation and storage. From 3 to 8 March 2024, DEHN can be found at stand B90 in hall 12.0 where it will be presenting solutions for the new DIN 18014 as well as technologies and products for electrical engineering, home and building automation and safety technology. DEHN will be showcasing protection solutions for industry, PV systems and residential buildings, including refurbishment, renovation and modernisation.
