## Summary description

The Ergom KOR 300/12 is a high-quality tin-plated copper ring terminal designed for reliable electrical connections. Engineered for 300 mm² conductors with a 12 mm stud hole, this terminal ensures excellent conductivity and corrosion resistance. It is an essential component for professional electrical installations, power distribution, and industrial wiring applications requiring secure and durable cable termination.

## Long description

The Ergom KOR 300/12 is a professional-grade tin-plated copper ring terminal engineered for high-performance electrical connections. Designed specifically for conductors with a cross-section of 300 mm², this terminal provides a secure and stable interface for 12 mm studs. The high-purity copper construction ensures optimal electrical conductivity, while the tin-plated finish offers superior protection against oxidation and environmental corrosion, making it a reliable choice for demanding industrial environments.
Advantages
This ring terminal stands out due to its robust construction and precision engineering, which facilitate efficient power transmission and minimize resistance at the connection point. The tin-plated surface treatment significantly extends the service life of the connection by preventing galvanic corrosion, even in challenging conditions. Its design allows for a firm, vibration-resistant attachment, ensuring long-term operational safety in critical power distribution systems.
Suitable for
Industrial power distribution panels
Heavy-duty electrical machinery and equipment
Large-scale electrical infrastructure projects
Battery bank connections and grounding systems
This terminal is not suitable for 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 stud sizes other than 12 mm, as an improper fit can lead to loose connections and overheating.
Key specifications
Material: Tin-plated copper
Conductor cross-section: 300 mm²
Stud hole diameter: 12 mm
Connection type: Ring terminal
To use the Ergom KOR 300/12, first strip the insulation from the end of the 300 mm² conductor to the appropriate length. Insert the conductor fully into the barrel of the terminal. Use a professional-grade hydraulic crimping tool calibrated for this specific terminal size to ensure a cold-welded connection. Once crimped, secure the terminal to the 12 mm stud using a matching bolt and washer, ensuring the connection is tightened to the manufacturer's specified torque.
What to consider before purchase
Verify the conductor cross-section matches the 300 mm² specification
Ensure the mounting stud diameter is exactly 12 mm
Confirm the availability of a compatible hydraulic crimping tool
Check the environmental conditions to ensure tin-plated copper is appropriate for the application
Usage recommendations
Always use a calibrated hydraulic crimping tool to achieve a secure connection. Avoid using manual hand pliers, as they cannot provide the necessary pressure for a 300 mm² conductor, which may result in high resistance and potential overheating.
