Ergom KOR 120/12 Tinned Copper Ring Terminal

The Ergom KOR 120/12 tinned copper ring terminal is a professional-grade electrical component designed to provide secure and efficient connections for heavy-duty wiring applications. Manufactured from high-quality copper and finished with a protective tin coating, this terminal is engineered to maintain optimal electrical conductivity while resisting oxidation and environmental degradation. It is specifically designed to accommodate conductors with a cross-section of 120 mm² and features a 12 mm stud hole for reliable mounting onto busbars, terminals, or equipment studs.

Advantages

The primary advantage of the Ergom KOR 120/12 terminal lies in its robust construction, which ensures long-term mechanical and electrical stability even under demanding operating conditions. The tin plating provides a critical barrier against corrosion, making it suitable for use in environments where moisture or chemical exposure might otherwise compromise a standard copper connection. Its precise design facilitates a consistent crimping process, resulting in a low-resistance contact point that minimizes heat generation and energy loss within the electrical circuit.

Suitable for

• Industrial power distribution systems
• Heavy-duty electrical panel wiring
• Grounding and earthing connections
• Large-scale infrastructure projects
• Automotive and marine power cabling

When it may not be suitable

This terminal is not intended for use with conductors that fall outside the specified 120 mm² cross-section range, as an improper fit will result in a weak or high-resistance connection. It is also not suitable for applications requiring non-metallic or insulated terminal bodies, as this component is designed for direct metal-to-metal contact.

Key specifications

• Material: Tinned copper
• Conductor cross-section: 120 mm²
• Stud hole diameter: 12 mm
• Connection type: Ring terminal

How to use

To install the Ergom KOR 120/12 terminal, first strip the insulation from the end of the 120 mm² conductor to the appropriate length required by the terminal barrel. Insert the conductor fully into the barrel, ensuring all strands are captured. Use a professional-grade hydraulic or mechanical crimping tool calibrated for this specific terminal size to create a permanent, gas-tight connection. Once crimped, secure the ring end to the desired stud using a compatible nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify the cross-section of your cable matches the 120 mm² requirement.
• Ensure the 12 mm stud hole is compatible with your existing equipment hardware.
• Confirm that you have access to a crimping tool capable of handling 120 mm² terminals.
• Check the environmental conditions to ensure tinned copper is the appropriate material for your specific application.

Usage recommendations: Always perform a pull test after crimping to ensure the conductor is securely fastened within the terminal. Regularly inspect connections in high-vibration environments to ensure that mounting hardware remains tight and free from oxidation.
