Manual earthing clamps with jaw (CLPBR-12 and CLPBR-16) are versions derived from the standard models or earthing clamps.

These clamps versions are provided with profiled jaws so that to allow the removal of layers of oxides, impurities and protective paint from the elements where they will be mounted, simultaneously with the tightening of the clamp, the ultimate goal of this operation being the creation of an appropriate contact resistance.

These clamp models are recommended for use on short-circuiting devices known to be applied in installations where ground plates include metallic elements that are painted or can be oxidized. The most familiar examples of such circumstances are lattice poles for high voltage lines or on the painted bars of ground straps existing in power stations.

The body of earthing clamps is a copper-aluminium alloy cast body item, and the scraping jaw and the elastic elements of the pressing system are made of steel, zinc-coated against corrosion.
