DEHNvario - the variable arrester family
DEHNvario protects a great variety of signals in power supply and information technology systems. With devices from this product family you can protect, e.g. voice alarm systems, loudspeaker systems and analogue camera systems.
Quick and easy installation thanks to practical direct plug-in technology. No tools needed! To replace the arrester, simply release the terminal unit and remove it from the enclosure. Not having to disconnect the wires individually saves time and hassle.
A further special feature in the enclosure design makes it easier to test the signal circuit. Special openings in the terminal units make it possible to test when wired, too.
Safe and easy earthing
Good to know: The earth contact of the DEHNvario can carry lightning and impulse current, so there is no need to install an additional equipotential bonding conductor. The arrester is simply connected to the equipotential bonding via the DIN rail.
