1968: PFISTERER registered the patent for a “compact tap connector”, “SCK” for
short, or “clamping ring”.
Today: The patent has become a bestseller. Now it's hard to imagine Central
European LV networks without SCK.
But nothing is so good that it can't be made even better. ISICOMPACT features a
new generation of clamping rings.
One for all. ISICOMPACT accepts main conductors in the range from 70 – 185 mm² and tap conductors from 6 – 70 mm² cross-section and can be used for all cable types.
Easy insertion. Tap conductors are inserted from the side; the time-consuming insertion from the front is eliminated.
Safer all round. ISICOMPACT is made from fully-insulating polyamide. That means: even more safety with live working.
Less is more. Only one bolt to connect all contact elements.
All under control. The captive stiffening ribs stop the contact plate penetrating into the insulation before the nut is tightened.
Permanent contact. A shear nut acts as a “built-in” torque-spanner to ensure the optimal tightening torque. The pressure plate is spring-loaded and so ensures continuous contact force.
No half measures. The assembly process is complete when the projecting bolt shears off. So you can forget about incomplete connections with ISICOMPACT! Mistakes are eliminated.
