Modularity Variable protection

The DEHNrapid LSA arrester series is a modular system of The variable arrester system provides protection for different
lightning current and surge arresters and can be combined applications. Powerful plug-in SPD blocks with integrated

ensures protection of terminal equipment.
The broad portfolio of arresters ensures an ideal protection
The surge arresters snap into the earthing frame and can be solution for the relevant application:
removed as a block, whenever required. • Lightning current carrying type 1 plug-in SPD blocks for
use at lightning protection zone 0 to 1 and higher
A
• Powerful type 2 plug-in SPD blocks for use at lightning
protection zone 0 to 1 and higher
B
• Application-specific type 3 protection modules and
earthing frames for variable protection of terminal equip-
ment can be plugged into the LSA disconnection blocks
or used for expanding the plug-in SPD blocks into com-
bined arresters
• Combined arrester consisting of a lightning current carry-
ing plug-in SPD block, earthing frame and protective plug.
