The LV Cable Piercing Connector 35–70 mm² / 35–70 mm² enables fast, safe, and maintenance-free connections for low-voltage ABC conductors. It allows branching from insulated aluminium or copper conductors without stripping insulation. The shear-head bolt provides precise torque control to ensure the contact teeth penetrate insulation without damaging conductor integrity. Constructed from high-strength, weather-resistant thermoplastic, it delivers excellent long-term performance in outdoor environments. Pre-applied seals and grease guarantee superior waterproof and corrosion-resistant performance, while the attached end cap prevents loss of parts during installation.

Standard: NFC 33 020, ANSI C119.5, EN 50483-4
