EARTHING + LIGHTNING PROTECTION

ROUND UP

Powerful PV overvoltage protection The new VAL-MB product family from Phoenix Contact provides powerful and compact pro- tective devices for photovoltaic applications with generator voltages of up to 1 500 Vdc.The protective devices are specially adapted to dc

Durable and powerful type-1 lightning current arrester The Flashtrab SEC-PLUS type-1 lightning current arresters from Phoenix Contact , which are particularly durable and powerful thanks to Safe Energy ControlTechnol-

ogy, have just been com- plemented by two product variants. The Flashtrab SEC-PLUS 440 product variant is particularly suit- ed to special industrial ap- plications with 440/690 V networks or 400 V power supply systems.The prod- ucts impress with their strong shock and vibration resistance. This compact variant can be used up to

application require- ments and certified by KEMA. Longer inlet fun- n e l s a nd h i gh e r screw shafts provide additional protec- tion against arcing. The product range includes protective devices for generator

400Awithout an additional back-up fuse.The Flashtrab SEC-PLUS 350 variant is used in the pre-metering area of the main feed, or in industrial applications. High voltage fluctuations and lightning current loads are no problem for the type-1 arrester.The good protection level and backup fuse-free use up to 315 A deliver additional ad- vantages. Both variants are pluggable and can be tested with the CheckMaster 2 test instrument for surge protection devices. Like any other SEC family type-1 arrester, the Flashtrab SEC-PLUS devices are also type-2 arrester tested and certified.The protec- tive devices of the SEC product family have been completely redeveloped and are based on Safe Energy ControlTechnology (SEC).The spark gap safely prevents any power supply secondary current.This means that the load of the entire installation is reduced to a minimum in the event of a lightning event.

voltages of 600Vdc, 1 000Vdc and 1 500Vdc, as type-1/2 lightning current arresters, as well as pure type 2 surge protection devices. Variants are available with or without remote signaling contact. All protective devices have a short-circuit protection of 2 000 A and can also be used in high-altitude plants up to 6000 meters in altitude. Enquiries:Tony Rayner.

Surge Protection Reinvented

Safe Energy Control technology is the basis for durable and powerful lightning and surge protection. The revolutionary spark gap safely prevents any line follow current. This protects your system, including fuses and arresters. For most applications, this means that a separate arrester backup fuse is no longer needed. The compact, plug-in arresters make installation easy. Keep your systems failsafe
