Ergom KDA 70/12 Aluminum Ring Terminal

The Ergom KDA 70/12 aluminum ring terminal is a professional-grade electrical component designed for secure and efficient termination of aluminum conductors. This terminal is specifically engineered to accommodate 70 mm² cable cross-sections and features a 12 mm stud hole, making it a reliable choice for heavy-duty power distribution and industrial electrical infrastructure. Its robust construction ensures low contact resistance and long-term stability in demanding electrical environments.

Advantages

The primary advantage of the Ergom KDA 70/12 is its high-quality aluminum composition, which provides excellent electrical conductivity and corrosion resistance when properly installed. The ring terminal design ensures a firm, vibration-resistant connection to busbars or equipment terminals, reducing the risk of overheating or connection failure. Its precise manufacturing allows for consistent performance across various industrial applications, ensuring that electrical systems remain safe and operational under load.

Suitable for

• Power distribution cabinets and switchgear
• Industrial electrical installations
• Connecting aluminum conductors to busbars
• Heavy-duty electrical infrastructure projects

When it may not be suitable

This terminal is designed exclusively for aluminum conductors and may not be suitable for copper cables due to potential galvanic corrosion issues if not managed with appropriate bimetallic connectors or specialized jointing compounds. It is also not intended for use in environments where the cable size does not match the 70 mm² specification or where the stud size significantly differs from the 12 mm requirement.

Key specifications

• Material: Aluminum
• Conductor cross-section: 70 mm²
• Stud hole diameter: 12 mm
• Terminal type: Ring terminal

How to use

To install the Ergom KDA 70/12, first strip the insulation from the aluminum conductor to the appropriate length. Ensure the conductor surface is clean and free of oxidation. Insert the conductor fully into the terminal barrel and use a professional hydraulic crimping tool with the correct die set to achieve a secure, permanent mechanical and electrical bond. Once crimped, the terminal can be bolted onto the desired contact point using a 12 mm bolt, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify the conductor cross-section matches the 70 mm² requirement
• Ensure the mounting stud size is compatible with the 12 mm hole
• Confirm the compatibility of the aluminum material with your existing cable type
• Use appropriate crimping tools to ensure a reliable connection

Usage recommendations

Always apply a suitable electrical contact grease to the aluminum conductor before crimping to prevent oxidation and ensure long-term conductivity. Ensure that the crimping process is performed by qualified personnel using calibrated tools to maintain the integrity of the connection.
