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.
DEHNguard M: This surge arrester protects against surges caused by inductive coupling, remote lightning strikes and switching overvoltages.
DEHNcord 3P TT 275FM: The type 2 + type 3 surge arrester provides optimum protection for three-phase end devices.
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: The compact surge arrester offers reliable protection for information technology interfaces, in particular telecommunications connections up to VVDSL and G.fast (up to 1 G.bit/s) with interference-free data transmission. Optional connection of a twisted pair or a patch cable with RJ45 at the output. Tool-free installation thanks to push-in technology.
DEHNgate FF TV: The type 2 arrester protects the broadband connection
DEHNrapid LSA: The DEHNrapid arrester family is a modular system consisting of lightning current, surge and combined arresters. The arresters can be plugged into type 2 LSA disconnection strips. The lightning current-carrying 10 DA plug-in magazine is equipped with gas discharge arresters (optionally with visual fault indication) and disconnection strip contacts.
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.
BLITZDUCTORconnect CL2 BE: Space-saving, compact combined arrester in 6 mm width and push-in connection technology with status display to protect 2 single conductors with common reference potential and unbalanced interfaces.
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: The type 2 arrester is specially adapted for use in smart homes. It can simply be plugged into the terminal slot of the KNX components.
DEHNcord L 2P SN1860: Surge arrester for protection class II luminaires.
Security camera
Universal surge arrester for GBit Ethernet applications, Power over Ethernet (IEEE 802.3 compliant up to PoE++ / 4PPoE) and similar applications in structured cabling systems up to class E in indoor and outdoor areas in an IP66 rated enclosure impervious to dust and water.
