## Summary description

The Ergom KDR 300/12 is a high-quality tinned copper ring terminal designed for reliable electrical connections. With a 300 mm² cross-section and a 12 mm stud hole, this terminal ensures excellent conductivity and corrosion resistance. It is ideal for professional electrical installations, power distribution, and grounding applications where a secure and durable connection is required.

## Long description

The Ergom KDR 300/12 tinned ring terminal is a professional-grade electrical component engineered for high-current applications. Constructed from high-conductivity copper and finished with a protective tin coating, this terminal provides a robust and reliable connection for heavy-duty electrical systems. Designed to accommodate a 300 mm² conductor, it ensures optimal electrical performance and long-term stability in demanding environments.
Advantages
The primary benefit of this terminal is its superior material composition, which minimizes electrical resistance and prevents oxidation over time. The tin plating acts as a barrier against environmental factors, making it highly resistant to corrosion even in challenging conditions. Its precise design ensures a secure mechanical fit, which is essential for maintaining electrical integrity and preventing overheating in high-power circuits.
Suitable for
Industrial power distribution systems
Heavy-duty grounding and earthing applications
Large-scale electrical infrastructure projects
Connection of high-capacity power cables
This terminal may not be suitable for applications involving conductors with a cross-section significantly smaller or larger than 300 mm², as this would compromise the mechanical and electrical integrity of the crimp. It is also not intended for use with non-copper conductors without appropriate transition adapters, as galvanic corrosion could occur.
Key specifications
Material: Tinned copper
Conductor cross-section: 300 mm²
Stud hole diameter: 12 mm
Type: Ring terminal
To use the Ergom KDR 300/12, first strip the insulation from the end of the cable to the appropriate length. Insert the conductor fully into the barrel of the terminal. Using a professional-grade hydraulic crimping tool calibrated for 300 mm² terminals, apply sufficient pressure to create a cold-welded connection between the copper wire and the terminal barrel. Ensure the crimp is uniform and secure before installing the terminal onto the 12 mm stud using a compatible nut and washer.
What to consider before purchase
Verify that your cable cross-section is exactly 300 mm²
Ensure your crimping tool is compatible with this terminal size
Check that the 12 mm stud size matches your connection point
Confirm the environmental conditions are suitable for tinned copper
For optimal performance, always use a calibrated hydraulic crimping tool and ensure the cable surface is clean and free of oxidation before installation. Periodically inspect the connection for signs of thermal stress or loosening in high-vibration environments.
