R3&A Limited
DEHN History. DEHN provides Surge and Lightning Protection Solutions around the world for over 100 years and has
become a worldwide known company with several subsidiaries and partners, like
R3&A Limited, in foreign countries.
The natural phenomenon of Lightning is impressing and unique. Lightning represents a stunning combination of nature’s beauty
and awesome power. However its destructive force destroys great economic assets every year.

Although lightning currents conducted in modern electrical circuits can cause immediate and catastrophic equipment failure,
surges from induced lightning and power switching operations are smaller but are more numerous and can result in equipment
non-operation, lockup or damage. Approximately 24 out of 100 cases of damage to electronic equipment are caused by surges.

Our mission is “to protect life and property from hazards of lightning and surges”. Lightning cannot be prevented, but proper
implementation of DEHN’s Lightning and Surge protection solutions can safely divert Lightning and Surge currents away from
ourselves, our homes and our business.

many of them have a decisive influence on the status of the international standards and therefore underlined the worldwide
leading position of DEHN + SÖHNE.
