 We offer a best solutions for Residents, Office and Commercial Buildings. Surges are a great danger. Direct, nearby and remote lightning strikes as well as switching operations in electric power stations can seriously damage buildings and systems. Many buildings and systems are exposed to lightning strikes and discharges, switching overvoltages, surges caused by short-circuits and switching off inductive loads. Apart from power supply systems, reliably functioning information technology systems are indispensable for smooth operation in office and administration building 

In modern households, electrical devices and systems make life easier:

• TVs, stereo and video equipment, satellite systems
• Electric cookers, dish washers and washing machines, driers, refrigerators / freezers, coffee machines, etc.
• Laptops / PCs / tablet PCs, printers, smartphones, etc.
• Heating, air-conditioning and ventilation systems.

First step: System protection:-
The first step is to consider all lines leaving or entering the building: Power supply / telephone / lighting lines, TV / SAT connections, connections for PV systems, etc. In residential buildings, meters and sub-circuit distribution boards are often placed in one enclosure. For this purpose, DEHNshield comes in different versions to protect both the installation and the terminal devices on the power supply side, even in case of direct lightning strikes. DEHNbox can be provided for the telephone connection e.g. via DSL / ISDN. This arrester is sufficient to ensure safe operation of the DSL router. DEHNrail and BLITZDUCTORXT protect the controller of the heating system, which is often located in the basement. If there are further distribution boards, DEHNguard® surge arresters are to be installed.

Second step: Protection of terminal devices:-
The next step is to protect all terminal devices, which are fed by several power supply systems, by installing surge protective devices right at their inputs. These terminal devices include TVs, video and stereo equipment as well as alarm and video surveillance systems. The antenna amplifiers can be protected by means of DEHNgate.
