®
DEHNrapid consists of powerful lightning current and
surge arresters for protecting information technology and
safety systems. The lightning current carrying components
have a discharge capacity up to 2.5 kA (10/350 µs) per
core. The DEHNrapid modular system allows the user to se-
lect an optimal combination for every application.
… protection thanks to its modularity
The modular design allows to combine the individual
elements to form a protection system which meets the
requirements on site. The protection elements are harmo-
nised and can be combined, thus ensuring flexible use and
an optimal solution – and therefore an excellent protective
effect. Comprehensive installation and mounting accesso-
ries complete the portfolio.

... and tested safety
Tests in the DEHN test laboratory demonstrate that
DEHNrapid arresters can handle impulse loads up to 2.5
kA (10/350 µs) per core. The integrated fail-safe function
protects terminal equipment from dangerous interference,
even in case of arrester overload.

The VdS* certificate recommends to use DEHNrapid surge
protective devices for safety systems and installations
requiring high availability.
