Ergom KDR 120/12 Tinned Ring Terminal for 120mm² Cable

The Ergom KDR 120/12 is a professional-grade tinned copper ring terminal engineered for secure and efficient electrical terminations. Designed specifically for 120mm² cross-section cables, this terminal features a 12mm stud hole, providing a robust connection point for heavy-duty electrical systems. The high-quality tin plating offers superior protection against oxidation and environmental factors, ensuring long-term reliability in demanding industrial environments.

Advantages

This ring terminal excels due to its high-conductivity copper construction, which minimizes resistance and prevents overheating in high-current applications. The precision-engineered design ensures a tight fit on the cable, while the durable tin coating provides excellent corrosion resistance, making it suitable for both indoor and outdoor installations. Its structural integrity allows for stable electrical contact, reducing the risk of connection failures in critical power distribution systems.

Suitable for

• Power distribution panels and switchgear
• Industrial machinery and heavy equipment wiring
• Battery bank connections and grounding systems
• Large-scale electrical infrastructure projects

When it may not be suitable

This terminal is not intended for use with cables that have a cross-section significantly smaller or larger than 120mm², as this would compromise the mechanical and electrical integrity of the connection. It is also not suitable for applications requiring specialized insulation materials if the environment involves extreme chemical exposure beyond the capabilities of standard tinned copper.

Key specifications

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

How to use

To install the Ergom KDR 120/12, first strip the insulation from the end of the 120mm² cable to the appropriate length. Insert the conductor into the barrel of the terminal. Use a professional-grade hydraulic or mechanical crimping tool specifically calibrated for 120mm² terminals to ensure a secure, gas-tight crimp. Once crimped, place the ring terminal over the corresponding 12mm stud and secure it firmly with a nut and washer to ensure optimal contact pressure.

What to consider before purchase

• Verify that your cable cross-section is exactly 120mm²
• Ensure the mounting stud diameter matches the 12mm hole size
• Confirm that you have access to a compatible heavy-duty crimping tool
• Check the environmental conditions to ensure tinned copper meets your requirements

Usage recommendations

Always perform a pull test after crimping to ensure the connection is mechanically sound. Ensure that the contact surfaces of the stud and the terminal are clean and free of debris to maintain maximum electrical conductivity.
