Ergom KDR Ring Terminal, Tinned Copper, 120mm² Cable Cross-Section, 10mm Stud Hole

The Ergom KDR ring terminal is a professional-grade electrical connector engineered for secure and efficient cable termination. Constructed from high-quality tinned copper, this terminal provides superior electrical conductivity while offering robust protection against oxidation and environmental corrosion. Designed specifically for 120mm² cable cross-sections, it features a 10mm stud hole, ensuring a precise and stable fit for various bolted electrical connections in demanding environments.

Advantages

The primary benefit of the Ergom KDR terminal lies in its durable tinned copper construction, which maintains low contact resistance over long periods of operation. The tin plating prevents galvanic corrosion, making it highly reliable for both indoor and outdoor electrical installations. Its design facilitates a strong mechanical bond when tightened, reducing the risk of overheating or connection failure in high-current applications.

Suitable for

• Industrial power distribution systems
• Automotive electrical wiring
• Switchgear and control panel assembly
• Heavy-duty machinery power connections
• Renewable energy infrastructure

When it may not be suitable

This terminal is not intended for use with cables that do not match the 120mm² specification, as improper sizing can lead to poor electrical contact and potential safety hazards. It is also not suitable for applications requiring specialized materials beyond standard copper, such as high-temperature environments exceeding the thermal limits of the tin coating.

Key specifications

• Material: Tinned copper
• Cable cross-section: 120mm²
• Stud hole diameter: 10mm
• Connector type: Ring terminal

How to use

To install the terminal, first strip the insulation from the end of the 120mm² cable to the appropriate length. Insert the conductor fully into the barrel of the terminal. Use a professional hydraulic or mechanical crimping tool specifically calibrated for 120mm² terminals to ensure a gas-tight connection. Once crimped, secure the ring terminal to the desired contact point using a 10mm bolt and nut, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify the cable cross-section matches 120mm² exactly
• Ensure the mounting surface accommodates a 10mm bolt
• Confirm the availability of a compatible heavy-duty crimping tool
• Check environmental conditions for compatibility with tinned copper

Usage recommendations

Always perform a pull test after crimping to ensure the cable is securely fastened within the terminal barrel. Ensure that the contact surfaces are clean and free of debris before bolting the terminal to the busbar or terminal block to maintain optimal conductivity.
