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.
DEHNshield Basic: For DIN rails up to 160 A. This combined arrester is directly mounted at the entrance point into the building. It protects the electrical installation in the immediate vicinity.
DEHNguard M: This surge arrester protects against surges caused by inductive coupling, remote lightning strikes and switching overvoltages.
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.
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.
DC side, if separation distance is kept for 1 MPP input
DEHNcube YPV SCI 1000 FM: 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
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.
DEHNcord R: Surge arrester for electric Venetian blinds; This type 2 arrester protects sensitive electric shutters. Plug-and-play: It is easily and quickly mounted in the form of an adapter solution.
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.
DEHNgate FF TV: This type 2 arrester protects broadband connections
DEHNprotector TV: Combined surge protection for the power and antenna side of a TV, radio or SAT receiver.
DEHNrail: Four-pole surge arrester consisting of a base part and plug-in protection module for 230 / 400 V systems; the FM version has a floating remote signalling contact.
BLITZDUCTOR pluggable module: The universal and pluggable DIN rail mounted arresters of the BLITZDUCTOR SP/XT/XTU series protect measuring and control circuits, bus systems and telecommunication systems.
BLITZDUCTOR base part: The universal and pluggable DIN rail mounted arresters of the BLITZDUCTOR SP/XT/XTU series protect measuring and control circuits, bus systems and telecommunication systems.
DEHNguard M: Multi-pole type 2 surge arrester consisting of a base part and plug-in protection modules. For protecting charging posts and wall boxes for e-mobility.
BUStector: This type 2 arrester is designed for use in smart homes. It can be easily snapped into the slot of KNX components.
DEHNcord L 2P SN1860: Surge arrester for protection class II luminaires.
