## Long description

The Erko ARC tubular aluminum ring terminal is a high-quality component engineered for the secure termination of 10 mm² aluminum conductors. Designed for professional electrical installations, this terminal features a robust tubular construction that ensures a reliable and long-lasting electrical connection. It is specifically configured for use with M25 studs, making it an essential part for power distribution systems and industrial wiring projects where mechanical strength and consistent conductivity are required.
Advantages
This terminal offers exceptional performance due to its specialized aluminum construction, which is optimized for electrical conductivity and resistance to mechanical stress. The tubular design facilitates a precise crimping process, ensuring that the conductor remains firmly in place while maintaining a low-resistance contact point. Its durable build quality provides stability in demanding environments, reducing the risk of connection failure and ensuring safety in power distribution networks.
Suitable for
Industrial power distribution systems
Electrical panel wiring
Aluminum conductor terminations
Infrastructure and utility electrical projects
When it may not be suitable
This terminal is specifically designed for aluminum conductors and may not be suitable for copper wiring due to potential galvanic corrosion issues. It is also not intended for use with stud sizes other than M25, as an incorrect fit can compromise the integrity of the electrical connection.
Key specifications
Conductor cross-section: 10 mm²
Stud size: M25
Material: Aluminum
Terminal type: Tubular ring terminal
How to use
To use the terminal, first strip the insulation from the end of the 10 mm² aluminum conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool specifically rated for aluminum tubular terminals to compress the barrel onto the conductor. Once crimped, place the ring end over the M25 stud and secure it firmly with a compatible nut and washer to ensure a stable electrical contact.
What to consider before purchase
Verify that the conductor material is aluminum to prevent compatibility issues.
Ensure the stud size in your installation is exactly M25.
Confirm that you have the correct crimping tool for aluminum tubular terminals.
Usage recommendations
Always ensure that the contact surfaces are clean and free of oxidation before installation. Using an appropriate contact grease for aluminum connections is recommended to maintain long-term conductivity and prevent corrosion.
