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.
For 40 mm busbar systems up to 160 A
DEHNshield ZP: This combined arrester with type 1+2+3 protective effect is quickly and easily mounted at the entrance point into the building. Your benefit: It protects the electrical installation in the immediate vicinity and the smart meter and smart meter gateway integrated in the area upstream of the meter.
For DIN rails up to 160 A
DEHNshield: This combined arrester is mounted directly at the entrance point into the building. It protects the electrical installation in the immediate vicinity. Ideally suited for retrofitting.
DEHNguard M: This surge arrester protects from surges caused by inductive coupling, remote lightning strikes and switching overvoltages. It must be installed downstream of the meter. Thus, protection of the smart meter and smart meter gateway is not ensured.
DEHNflex: The DEHNflex type 3 arrester is mounted directly on the terminal device. It is ideally suited for installation in cable ducts and installation boxes. Other places of installation are possible.
DEHNbox TC 180: This combined arrester protects from direct lightning strikes and surges.
It provides safety for the telephone and DSL connection. Its compact design allows fast installation in new buildings and easy retrofitting in existing buildings.
DC side, if separation distance is kept for 1 MPP input
DEHNcube YPV SCI 1000 1M: The DEHNcube YPV SCI type 2 arrester offers comprehensive protection for a PV system – in a single enclosure. It is directly mounted upstream of the inverter. In case of a cable length of more than 10 metres between the PV system and the inverter, an additional arrester is required in the roof area. For 1 MPP input.
DC side, if separation distance is kept for 2 MPP inputs
DEHNcube YPV SCI 1000 2M: The DEHNcube YPV SCI type 2 arrester offers comprehensive protection for a PV system – in a single enclosure. It is directly mounted upstream of the inverter. In case of a cable length of more than 10 metres between the PV system and the inverter, an additional arrester is required in the roof area. For 2 MPP inputs.
DC side, if separation distance is not kept for 1 MPP input
DEHNcombo YPV SCI: Prewired type 1 + type 2 combined arrester for PV generator circuits. Combined disconnection and short-circuiting device with safe electrical isolation (patented SCI principle)
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.
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 FF5 TV: Five-channel surge arrester for 75-ohm antenna systems. Special design for SAT antenna splitters and multi-switches. The arrester fulfills the shielding requirements of class A according to EN 50083-2.
DEHNgate GFF TV: Combined arrester with F connection with remote power supply for 75-ohm satellite and broadband systems. The arrester meets the increased shielding requirements of class A according to EN 50 083-2. Suitable for space-saving installation in all common TV and satellite applications.
DEHNprotector TV: Combined surge protection for the power and antenna side of a TV, radio or SAT receiver.
DEHNrail M 4P: Protection of the voltage supply of the heat pump.
BLITZDUCTOR plug-in module: Protects home automation communication and measuring lines (heat pump). Base part and plug-in module are directly mounted on the electronic components of, e.g., heating and air-conditioning systems or heat pumps requiring protection.
BLITZDUCTOR base part: Protects home automation communication and measuring lines (heat pump). Base part and plug-in module are directly mounted on the electronic components of, e.g., heating and air-conditioning systems or heat pumps requiring protection.
