Equipotential Bonding

UNI Earthing Clamps
For integrating the mounting systems, e.g. of PV installations in the functional equipotential bonding / functional earthing (black conductor
possible) and lightning equipotential bonding.
The StSt contact plate (intermediate element) allows different conductor materials (Cu, Al, St/tZn and StSt) to be connected to the usual
mounting systems, e.g. to aluminium, without the risk of contact corrosion.
