Erko ACL 240-120/1 Sealed Al-Cu Reduction Connector 240mm² to 120mm²

The Erko ACL 240-120/1 is a high-quality sealed Al-Cu reduction connector engineered to facilitate a secure and durable transition between aluminum and copper conductors. Designed for professional electrical infrastructure, this connector effectively manages the connection of a 240mm² aluminum conductor to a 120mm² copper conductor, ensuring optimal electrical conductivity while preventing the common issue of galvanic corrosion that typically occurs when these two metals are joined directly.

Advantages

This connector provides a robust solution for complex electrical systems by utilizing a sealed design that protects the contact point from environmental factors such as moisture and oxidation. The precision engineering of the Erko ACL 240-120/1 ensures a low-resistance connection that maintains its integrity over long periods of operation. By utilizing specialized materials and construction, it minimizes the risk of overheating and mechanical failure, making it a reliable choice for critical power distribution networks.

Suitable for

• Transitioning between aluminum and copper power cables
• Professional electrical distribution installations
• Industrial power grids requiring corrosion-resistant connections
• Outdoor or high-humidity electrical environments

When it may not be suitable

This connector is not intended for use with conductors outside the specified cross-section range of 240mm² and 120mm². It is also not suitable for applications involving non-standard cable materials or environments where mechanical vibrations exceed the design limits of the connector.

Key specifications

• Conductor range: 240mm² (Al) to 120mm² (Cu)
• Material: Aluminum-Copper bimetallic construction
• Design: Sealed for environmental protection
• Function: Reduction connector for dissimilar metals

How to use

To use the Erko ACL 240-120/1, ensure that the conductors are properly stripped of insulation according to the required length. Insert the aluminum conductor into the designated side and the copper conductor into the reduction side. Use appropriate professional crimping tools to apply the necessary pressure to create a permanent, gas-tight connection. Ensure that the sealing mechanism is intact and properly positioned to prevent the ingress of external elements.

What to consider before purchase

• Verify the cross-sectional area of your cables matches the 240mm² to 120mm² specification
• Ensure you have the correct crimping dies for this specific connector type
• Confirm the installation environment is compatible with sealed bimetallic connectors

Usage recommendations

Always follow local electrical codes and manufacturer guidelines during installation. Ensure that the contact surfaces are clean and free of debris before crimping to maintain maximum conductivity and long-term reliability.
