T B S<strong>New</strong> Combi Controllerand Surge Controller:Effectivesurge protection„Made by <strong>OBO</strong>“Small in size, big in performance:The new <strong>OBO</strong> Combi Controllertype V 25-B+C is a compact lightningand surge arrester of requirementclass B and C to DIN VDE0675 Part 6 (A1/A2). The devicewas developed specially for use indwellings (to VDS 2031). If the buildinghas an external lightning protectionsystem (to DIN VDE 0185Part 100), the Combi Controllerensures effective and safe lightningprotection potential equalisation.The V 25-B+C is also capable ofprotecting buildings connected toan overhead power line. The deviceis designed to dissipate the highlightning energies that may occuron an overhead line in the event ofa direct lightning strike.Because of its low protection level(< 900 V) and its varistor-baseddesign,the Combi Controlleris also well suited to filtering anddiverting transients (short-term voltagesurges) from power supplylines.A significant advantage of the deviceis its compact design. This isthe result of the fact that only a17.5 mm housing is needed foreach arrester element.The <strong>OBO</strong> SurgeControllerV 20-C is apowerful surgearrester ofrequirementclass C. Withits nominaldischarge currentIn of 20kA (8/20), itcan protectbuildings fromdamage dueto energy-richvoltage surgesinjected galvanically,inductivelyor capacitively.The Surge Controller is usuallyused in distribution boards, whereit can be quickly and easily mountedon top-hat rails (DIN EN50022). Correct installation is madeeasier by a pre-wired base and clearlymarked terminals.With TN-S, TT and IT mainssystems, the 3+1 connection variantshould be used: The new <strong>OBO</strong>Combi Controller C 25-B+C withnon-reversible connections, combinedwith arrester elements V 25-B+C and V 20-C, ensures a highdegree of security against voltagesurges.The C 25-B+C (NPE spark gaparrester) is equipped with a newtype of protection against incorrectconnection which reliably preventsconfusion of the arrester elementsand ensures technically correctinstallation of the protection devices.<strong>OBO</strong><strong>Blick</strong> 1/<strong>2002</strong> | 15
