Al-Cu piercing connector 16-95/1.5-50 single-sided with breakaway nut Z208Z

Universal Al-Cu piercing clamp for connections

This single-sided Al-Cu piercing clamp, designed for conductors with cross-sections of 16-95 mm² for the main conductor and 1.5-50 mm² for the branch, is a reliable solution for creating safe and durable electrical connections. Designed for both professional installers and end-users, this clamp combines a solid construction with ease of installation.

Construction and application

The clamp is made of high-quality materials, guaranteeing its durability and resistance to weather conditions. A hermetic plastic housing protects against moisture and UV radiation. The clamp jaws made of tinned copper alloy, filled with contact paste, ensure optimal current conductivity and minimize the risk of corrosion. The clamping screws protected by hot-dip galvanizing further increase corrosion resistance. This clamp is ideal for branching from overhead conductors – both insulated and uninsulated – to insulated Al-Cu conductors.

Advantages and benefits

• Versatility: The ability to connect aluminum and copper wires in one clamp eliminates the need for additional connecting elements.
• Safety: A tear-off nut ensures proper clamping without the need for a torque wrench (the nut breaks when a force of 14Nm or 18Nm is exceeded). The possibility of re-tightening with a certified torque wrench provides flexibility in case of adjustment needs.
• Durability: Hot-dip galvanizing of the clamping screws and filling the jaws with contact paste ensure long-term connection reliability.
• Easy installation: The clamp design allows for quick and easy installation, which translates to time savings during installation. Additionally, the shape of the clamp allows it to be mounted in a front-end wrench.
• Moisture protection: Seals protect against moisture entering the conductive elements, increasing safety of use.
• Insulation: The clamp is insulated, minimizing the risk of short circuits and electric shock.
• Multiple uses: Despite the presence of a tear-off nut, the clamp can be used multiple times after proper tightening with a torque wrench.

The Z208Z clamp is a modern solution for demanding electrical installations, combining functionality, safety and durability.
