Ergom KO 120/12 Tinned Copper Ring Terminal

The Ergom KO 120/12 tinned copper ring terminal is a professional-grade component engineered for secure and efficient electrical terminations. Designed to accommodate copper conductors with a cross-section of 120 mm², this terminal features a 12 mm stud hole, making it compatible with standard industrial bolts and connection points. The high-quality copper construction ensures excellent electrical conductivity, while the tin plating provides a robust barrier against oxidation and environmental corrosion, ensuring long-term reliability in demanding electrical systems.

Advantages

This ring terminal offers superior mechanical strength and electrical performance due to its high-purity copper base. The precision-engineered design allows for a firm crimp, which minimizes contact resistance and prevents overheating during high-current operations. The tin-plated finish significantly extends the service life of the connection by preventing galvanic corrosion, even in humid or industrial environments. Its robust construction makes it an essential choice for maintaining stable power distribution and grounding integrity in complex electrical infrastructures.

Suitable for

• Power distribution panels and switchgear
• Industrial machinery and equipment wiring
• Grounding systems for electrical installations
• Heavy-duty automotive and marine electrical connections

When it may not be suitable

This terminal is specifically designed for copper conductors and should not be used with aluminum wires to avoid galvanic corrosion issues. It is also not intended for applications requiring high-temperature resistance beyond the standard limits of tinned copper or for connections where the stud size significantly deviates from the 12 mm specification.

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 KO 120/12 terminal, first strip the insulation from the end of the copper conductor to the appropriate length. Insert the conductor fully into the barrel of the terminal. Use a professional-grade hydraulic or manual crimping tool compatible with 120 mm² terminals to ensure a secure mechanical bond. Once crimped, place the ring over the designated stud and tighten the nut firmly to ensure optimal contact pressure.

What to consider before purchase

• Verify that the conductor cross-section matches the 120 mm² rating.
• Ensure the stud size of your equipment matches the 12 mm hole diameter.
• Confirm that you have the correct crimping tool for this specific terminal size.
• Check the environmental conditions to ensure tinned copper is appropriate for your application.

Usage recommendations

Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid over-tightening the nut on the stud to prevent mechanical stress on the terminal or the connection point.
