Erko ACL 35-16/1 Sealed Aluminum-Copper Reduction Connector 35mm² to 16mm²

The Erko ACL 35-16/1 is a professional-grade sealed reduction connector engineered to facilitate secure and reliable electrical transitions between aluminum and copper conductors. Designed to bridge a cross-section reduction from 35mm² to 16mm², this component is essential for maintaining electrical integrity in systems where different metal types must be joined. The sealed construction provides robust protection against environmental factors, preventing oxidation and ensuring long-term conductivity in demanding electrical installations.

Advantages

This connector offers a specialized solution for preventing galvanic corrosion, which typically occurs when aluminum and copper are joined directly. By utilizing a sealed design, the Erko ACL 35-16/1 effectively isolates the connection point from moisture and atmospheric contaminants, thereby maintaining low contact resistance over time. Its precise engineering ensures a stable mechanical and electrical bond, which is critical for safety and efficiency in power distribution networks.

Suitable for

• Transitioning between aluminum and copper power cables
• Electrical distribution panels and switchgear
• Industrial and residential power supply systems
• Projects requiring a reduction from 35mm² to 16mm² conductors

When it may not be suitable

This connector is not intended for use with conductors outside the specified 35mm² and 16mm² cross-sections. It is also not suitable for applications involving high-vibration environments unless additional strain relief measures are implemented according to local electrical codes.

Key specifications

• Conductor type: Aluminum to Copper
• Input cross-section: 35mm²
• Output cross-section: 16mm²
• Design: Sealed reduction connector
• Material: Corrosion-resistant alloy

How to use

To install the connector, ensure that both the aluminum and copper conductors are properly stripped of insulation to the required length. Insert the conductors into their respective sides of the connector, ensuring they are fully seated. Use the appropriate crimping tool specified for this type of connector to achieve a secure mechanical bond. Verify that the seal remains intact throughout the installation process to ensure the connection is protected from external elements.

What to consider before purchase

• Verify the cross-section of your existing cables
• Ensure compatibility with your specific crimping equipment
• Check local electrical regulations regarding Al-Cu connections

Usage recommendations: Always clean the conductor surfaces before insertion to remove any oxide layers. Ensure the connector is installed in a location that allows for periodic inspection if required by your facility's maintenance schedule.
