The new and comprehensive surge protection family for measurement and control technology in 6 mm overall width. The interfaces in C&I applications must be protected against surges, since coupling of surges on lines can interfere with or destroy signal inputs. It is therefore necessary that C&I devices be protected in their immediate vicinity. For this purpose, VARITECTOR SSC, with its compact terminal-block format, is ideal for this application. The protective circuits are matched to the current loops and to binary signals. Weidmuller VARITECTOR SSC products are tested according to the latest standards (IEC61643-21): They satisfy the safe short-circuit mode in the event of overload by AC currents in classes D1, C2 and C1. The products are ATEX-tested for use in intrinsically safe circuits.
