Erko AS 12-70/1 Sealed Aluminum Ring Terminal 12-70mm²

The Erko AS 12-70/1 is a high-quality sealed aluminum ring terminal engineered for the secure termination of aluminum conductors. Designed to accommodate wire cross-sections ranging from 12mm² to 70mm², this terminal provides a robust and reliable connection point for various electrical infrastructure projects. Its sealed construction is specifically developed to prevent oxidation and moisture ingress, ensuring long-term electrical conductivity and structural integrity in demanding environments.

Advantages

This terminal offers exceptional durability due to its specialized sealed design, which effectively protects the aluminum conductor from atmospheric corrosion and environmental degradation. By maintaining a stable contact surface, it minimizes resistance and prevents overheating, which is critical for the safety and efficiency of power distribution systems. The precision engineering of the Erko AS 12-70/1 ensures a consistent fit, facilitating professional-grade installations that meet rigorous technical standards.

Suitable for

• Electrical power distribution systems
• Industrial electrical installations
• Connection of aluminum conductors in outdoor or humid environments
• Infrastructure projects requiring long-term maintenance-free connections

This terminal may not be suitable for applications involving copper conductors without appropriate bimetallic transition adapters, as direct contact between copper and aluminum can lead to galvanic corrosion. It is also not intended for use in high-vibration environments where specialized locking terminals might be required.

Key specifications

• Material: Aluminum
• Conductor range: 12mm² to 70mm²
• Design: Sealed ring terminal
• Application: Aluminum conductor termination

To use the Erko AS 12-70/1, first strip the insulation from the aluminum conductor to the appropriate length required by the terminal barrel. Ensure the conductor surface is clean and free of oxidation. Insert the conductor fully into the terminal barrel and use a professional crimping tool compatible with aluminum terminals to apply the correct pressure. Proper crimping is essential to ensure a gas-tight connection that prevents moisture from entering the contact area.

What to consider before purchase

• Verify the cross-section of your aluminum conductor matches the 12-70mm² range
• Ensure the use of compatible crimping tools for aluminum terminals
• Check for the necessity of anti-corrosion contact grease if specified by local electrical codes
• Confirm the bolt size of your connection point matches the ring hole diameter

Usage recommendations

Always use a calibrated crimping tool designed specifically for aluminum connectors to ensure the integrity of the connection and prevent mechanical failure over time.
