In today’s modern world, the uninterrupted use of information technology and automation equipment is often taken for granted. However, lightning discharges, surges and over-voltages can be extremely harmful to equipment, resulting in physical damage, data loss and the associated cost of lost production. Today’s businesses constantly depend on reliable communication systems to function effectively; and multi-pair incoming communication cables that are often terminated on lightning current and surge arrester (LSA) strips can easily be protected with the DEHNrapid LSA as they enter the building.
The 10-way plug-in DEHNrapid SPD block simply plugs into the existing LSA strips on site and immediately provides Type 1 lightning protection for up to 10 pairs of cables. The universal lightning protection base is further expandable with individual fine surge protection modules, which coordinate with the upstream Type 1 protection and fit directly into the Type 1 SPD. They are available from 5 to 180 V with various signal protocols.
“A big advantage of the EM 2 DRL earthing plug is that other earthing plugs can be easily replaced by DRL protective plugs if measuring and control signals are applied to the relevant lines at a later date. In comparison, if an EL2 38EA LSA earthing module were to be used for earthing unused lines, extensive re-wiring work would be required,” says Alexis Barwise, MD of Dehn Protection South Africa.
