DEHNventil: the original.
Half the size, all the power.
Future-proof.
The new DEHNventil effortlessly replaces equivalent older devices, thus providing the maximum guarantee of future compatibility. Additionally, all DEHNventil models are now equipped with a remote signalling contact, which simplifies product selection significantly.
Find the right DEHNventil
Space-saving.
DEHNventil is now only half as big as its predecessor: with a space requirement of 4 standard DIN modules and with the option of lateral installation, you stay flexible. And additional space is available for new requirements, future components and easier assembly of components.
Powerful.
The multipole, modular, type 1+2+3 combined arrester protects installations from partial lightning currents and surges in just one single module in a compact design and impresses with a follow current extinguishing capability of 100 kArms.
Reliable.
The installed RAC spark gap responds extremely quickly and impresses with minimal residual energy. This means maximum safety and optimum preservation of downstream electronic installations and systems.
To the RAC Technology
Smaller, stronger, more reliable. The original since 1983.
Since 1910 DEHN is leading the way. We develop products that set new standards. The new DEHNventil is now only half as big as its predecessor. At the size of just 4 standard DIN modules and integrated remote signalling contact, the fourth generation of the type1+2+3 combined arrester provides full power and maximum protective effect at half the size.
Low cost for full power
More space in the switchgear cabinet
No more cramming in the switchgear cabinet: with its compact design, the DEHNventil leaves enough space for new components. More space also makes the installation of the DEHNventil itself and adjacent components easier.
Flexible installation point
Use the space gains optimally: the small design also enables lateral installation – this makes 0.5 m cable lengths easy to keep to. Due to the double-sided imprint, you can rotate the product by 180 degrees.
Quick module replacement
The spring-supported ejection mechanism allows for the entire plug-in block to be replaced quickly and effortlessly. A real time benefit during module replacement!
Less maintenance effort
After replacing the single module, all modes of protection directly have full capability again. And thanks to the integrated remote signalling contact, maintenance operations can be planned better and more effectively with 24/7 monitoring. Vibration shock testing ensures reliable use even under vibration stress.
Lower costs
With the type 1+2+3 combined arrester, costs for other devices and their installation are done away with – a smaller switchgear cabinet often also suffices as a result. The extra space in turn saves on transport and storage costs, since more products find space on the pallet.
Easy choice
With the integrated remote signalling contact in all models, you will easily find the right DEHNventil for your applications. The all-in-one solution protects systems and installations within a protection range of 10 m of cable length.
