Commerce trade and industry, national and local institutions, and the private household as well depend to an ever increasing extent on electronic equipment and information technology systems.
Failures of such highly sensitive systems are frequently caused by electrostatic discharges, switching overvoltages or overvoltages due to lightning strikes. Damage caused, in particular, by thunderstorm overvoltages have shown in the past years that electronic systems are at risk through electromagnetic fields and line-fed overvoltages at a distance of up to 1.5km from the point of the lightning strike.
At first there was the idea of
diverting lightning to the
ground without endangering
home or people. This was the

was not sufficient to protect
these devices. With the
experience of decades in the
field of external lightning

Therefore, the first generation
of surge protective devices
(SPDs) of DEHN & SOHNE was
introduced to the market in
Today, DEHN & SOHNE produce more
than 3,500 devices and components
for your safety.
