Type 2 surge arrester 5SD7443-8kk series

type 1type 3remote signaling

• Universal application in all main distribution cabinets due to compact design (47 mm) • Easy and quick installation on the 40 mm busbar with safety interlocking and protection against mismating • Cost and time savings in an additional supply upstream from the meter such as the modem or gateway • Three-pole remote signaling contact (-R) for monitoring the device function remotely • Compliance with requirements of the DIN VDE 0100-443 and -534 standards as well as DIN VDE AR-N 4100 The more than one million lightning strikes in Germany every year pose a considerable risk for buildings and systems that can be damaged due to the unhindered effect of lightning currents, overvoltage and power surges. In many cases however, it is not apparent that such damage has been caused by lightning currents, overvoltage and power surges. Overvoltage results in considerable damage to electrical and electronic equipment. Even brief transients in power supply lines or between electrical lines and other conductive parts (e.g. grounded metallic parts, ground) are sufficient to cause such damage. The damage patterns of destroyed lines, circuit boards or switchgear demonstrate this. Such damage can be prevented employing suitable overvoltage protection means.
