Description
Multi pin lightning arresters according to the requirements of the IEC 61643, EN 61643: Class I after 2013 is used the arrester at the transition of the interfaces 0 to 1 (according to IEC 1312-1) as a lightning protection potential compensation and is used in applications according to IEC 61643-12. By the use of a not ausblasenden radio link in combination with a high-performance varistor, the requirements for the verifiability of surge protection devices of Class I from the VDEW-directive. The discharger is close to the feed of the protected system into a commercially available installation/manifold installed. The VPU I 3+1 R 400V/25kA is in the TN-C and TN-CS network. With thermal separation device divides the varistor. If there is no protection is present, the color changes from green to red in the display window. In addition, the function state by a floating signaling contact (changer) is displayed.
