Ergom KOR 300/12 Copper Ring Terminal, Tin-Plated

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.
