Erko ARC 12 x 240mm Tubular Aluminum Ring Terminal

The Erko ARC 12 x 240mm tubular aluminum ring terminal is a professional-grade component engineered for the secure and reliable termination of aluminum conductors. Designed specifically for heavy-duty electrical systems, this terminal facilitates a stable connection for 240mm² cables, ensuring optimal electrical performance and mechanical integrity in demanding industrial environments.

Advantages

This terminal is constructed from high-quality aluminum, which offers excellent electrical conductivity and resistance to corrosion when installed correctly. The tubular design allows for efficient crimping, creating a permanent bond between the conductor and the terminal. Its robust build quality ensures long-term reliability in power distribution networks, minimizing the risk of overheating or connection failure under load.

Suitable for

• Industrial power distribution systems
• Large-scale electrical infrastructure projects
• Aluminum cable termination for heavy machinery
• Utility and power grid maintenance

When it may not be suitable

This terminal is specifically designed for aluminum conductors and should not be used with copper cables unless appropriate bimetallic transition methods are applied. It is not suitable for applications requiring high-flexibility fine-stranded cables that fall outside the specified cross-section range.

Key specifications

• Material: Aluminum
• Conductor cross-section: 240mm²
• Mounting hole diameter: 12mm
• Type: Tubular ring terminal

How to use

To install the terminal, first strip the insulation from the aluminum cable to the appropriate length. Ensure the conductor surface is clean and free of oxidation. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade hydraulic crimping tool with the correct die set corresponding to the 240mm² size to perform the crimp. Once crimped, the terminal can be secured to the busbar or contact point using a 12mm bolt.

What to consider before purchase

• Verify the compatibility of the terminal material with your specific cable type
• Ensure your crimping equipment is rated for 240mm² aluminum terminals
• Check the mounting space to ensure the 12mm hole fits your existing hardware

Usage recommendations

Always apply an appropriate contact grease to the aluminum conductor before crimping to prevent oxidation and ensure a long-lasting, low-resistance electrical connection.
