Extremely good – down to the finest detail.
The DEHNventil M2 series
With the DEHNventil M2 series, you're getting maximum performance in the smallest installation space. Flexible to use, the combined arresters protect industrial low-voltage switchgear reliably and without interruption with a compact single module. The tested Type 1 + 2 + 3 combined arresters in accordance with EN 61643-11 provide lightning equipotential bonding, surge protection and terminal device protection in just one device.
Technical details
What makes the
DEHNventil M2 series stand out
extremely powerful
The DEHNventil M2 series impresses with maximum power density: A high impulse current and short-circuit-current resistance of 100 kArms, combined with a modular design concept – with a size of just 4 standard DIN modules.
extremely quick
The integrated RAC spark gap technology sets unrivalled standards: Compared to other spark gap technologies, it quickly reduces lightning currents to a level that is safe for the downstream installation.
extremely universal
Available for all standard system configurations (multi-phase, single-phase), space-saving and flexible installation. The DEHNventil M2 series is the ideal "all-in-one solution" for a wide range of applications.
Technical features at a glance
1. Easy module replacement
2. Remote signalling contact for condition monitoring
3. Maximum width: 4 standard DIN modules
4. 2 PE connections for improving the protection level
A power density that is unrivalled
Never before has so much power been possible in so little space:
Suitable for all classes of LPS
The Type 1 + 2 + 3 combined arrester is therefore the first choice, particularly in industrial environments and for increased technical requirements.
Modularity
The plug-in block enables quick and safe replacement. All phases are replaced simultaneously.
Application in industry
Can be used in systems with short-circuit currents of up to 100 kArms.
Lower system load
The fast RAC technology largely isolates the downstream system from harmful lightning currents.
Safe and flexible installation support
Serial wiring with optionally available pin connection terminal for flexibility and safety during installation.
Highest mechanical load capacity
even with extreme lightning current loads such as direct strikes into the building (Itotal = 100 kA for lightning protection class I).
Surge protection in a
compact design
One series, many options
Easy installation
More room in the switchgear cabinet means easy installation and wiring of the DEHNventil, as well as adjacent components. The option of lateral installation helps you to maintain a cable length of 0.5 metres. 180°-rotated installations are also possible.
Optimal use of space and lower costs
The small space requirement of the DEHNventil can save costs if a smaller control cabinet is sufficient. With a width of just 4 standard DIN modules, the combined arrester frees up space for additional components.
Good to know: The DEHNventil M2 series protects terminal equipment within 10 metres of cable length. The costs associated with additional devices and their installation are done away with.
Can be used in all system configurations

RAC spark gap technology
Know-how you can rely on
Speed is safety: Because the RAC (Rapid Arc Control) technology reacts extremely quickly and allows less residual energy to pass through, downstream systems are protected and the service life of the connected devices is thus extended. With RAC technology, electric arcs are fed into the arcing chambers at lightning speed, split into individual sub-arcs and quenched.

Applications of the
DEHNventil M2 series
Reliable protection for power supply
The DEHNventil M2 series provides optimum protection for low-voltage main distribution boards. In buildings and facilities with important infrastructure, the surge arresters provide reliable surge protection for office complexes, shopping malls and medical care centres. In production processes and industrial applications, the DEHNventil M2 series protects critical processes and ensures uninterrupted production. In addition, surge arresters of the DEHNventil M2 series are essential components in energy-generating systems such as hydrogen electrolysis plants and other pioneering technologies. In the railway power supply sector, surge arresters make a significant contribution to the availability of digital interlockings, level crossing safety systems and point heaters.
