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.
The 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.
