Surge protection - Single-family house with external lightning protection

Surge protective devices protect electric / electronic systems and devices from damage caused by excessively high voltages. This dangerous interference energy is gradually broken down to a level corresponding to the rated impulse voltage.

Please note that the relevant arresters have to be energy-coordinated to ensure interaction of the individual protection stages.

A - Power supply

For DIN rails up to 160 A

DEHNshield Basic: This combined arrester is directly mounted at the entrance point into the building. It protects the electrical installation in the immediate vicinity.

Ideal for retrofitting.

Alternative

Main distribution board

DEHNventil: For protecting the power supply of low-voltage consumer's installations. Multipole type 1 + type 2 spark-gap-based arrester according to EN 61643-11.

Sub-distribution board

DEHNguard M: This surge arrester protects against surges caused by inductive coupling, remote lightning strikes and switching overvoltages. It must be installed downstream of the meter. Thus, the smart meter and smart meter gateway are not protected.

Protection of terminal equipment

DEHNflex: The type 3 DEHNflex arrester is mounted directly at the terminal device. It is ideal for installation in cable ducts and installation boxes. Other places of installation are possible.

B - Data and telecommunication technology

Telephone / Internet connection

DEHNbox TC 180: This combined arrester protects in case of direct lightning strikes and surges.
It provides safety for the telephone and DSL connection. Thanks to its compact design, it can be quickly mounted in new buildings and easily retrofitted in existing buildings.

C - Photovoltaic system

Inverter

DC side, if separation distance is kept for 1 MPP input

In case of a cable length of more than 10 metres between the PV system and the inverter, another arrester is required in the roof area. For 1 MPP input.

Inverter

DC side, if separation distance is kept for 2 MPP inputs

DEHNcube YPV SCI 1000 2M: The DEHNcube YPV SCI type 2 arrester provides comprehensive protection for your PV system – in a single enclosure. It is mounted directly upstream of the inverter. In case of a cable length of more than 10 metres between the PV system and the inverter, another arrester is required in the roof area. For 2 MPP Inputs.

Inverter

DC side, if separation distance is not kept for 1 MPP input

DEHNcombo YPV SCI: Prewired type 1 and type 2 -circuiting combined lightning current and surge arrester for use in photovoltaic generator circuits Combined disconnection and short device with safe electrical isolation (patented SCI principle)

 

D - Electric sun and privacy protection

Electric shutter

DEHNcord R: This type 2 arrester protects sensitive electric shutters. Plug-and-play: It is easily and quickly mounted in the form of an adapter solution.

E - Home-Office

Computer work station

DEHNprotector LAN100: This type 3 arrester protects both the network and data side from surges. Thus, it is ideally suited for DSL routers and computer work stations.

F - TV connection

TV/SAT system
