-n°3 Aluminium universal contact clamp, tested for high currents. CH12 hexagonal shank, for insertion on EF-type shank, and steel clamping screw protected with antioxidant galvanic treatment.
Clamping capacity:
-cylindrical conductors diameter 5 - 40 mm;
-flat bars 40 x 60 mm;
-Board bars 12 x 60 mm;
-45° inclined bars up to 28 mm.
-n°3 extra-flexible short-circuit cables made of electrolytic copper coated with a transparent sheath, for connection between the clamps and the central connector. Cross-section 70 mm², length 0.75 m, complete at the ends with tinned electrolytic copper cable lugs and additional transparent heat shrink tubing reinforcement.
-Three-pin connector. -Earth cable, length 2 m.
-Earth clamp, clamping capacity up to 22 mm.
-Insulation strap made of glass-fibre reinforced vinylester resin tubing for operating contact clamps, length 1.35 m in two elements with quick-connect fitting.
- Sturdy canvas bag for containing and transporting the device and foil.
