For integrating mounting systems e.g. of PV installations into the functional equipotential bonding / functional earthing (optionally black conductor) and lightning equipotential bonding according to IEC/EN 62305-3.
The StSt contact plate (intermediate element) allows for different materials of conductors (Cu, Al, St/tZn and StSt ) to be connected to the usual mounting systems, e.g. to aluminium, without the risk of contact corrosion.
The double cleat design allows for easy and quick interconnection of the profiles, e.g. by feed-through wiring.
