Ergom KO 35/12 Tinned Copper Ring Terminal

The Ergom KO 35/12 is a professional-grade tinned copper ring terminal engineered to provide secure and efficient electrical terminations. Designed for conductors with a cross-section of 35 mm², this terminal features a 12 mm stud hole, ensuring compatibility with standard industrial bolts and connection points. The high-quality copper construction combined with a protective tin coating offers superior electrical conductivity and long-term resistance to oxidation and environmental corrosion.

Advantages

This ring terminal stands out due to its robust construction which guarantees a stable electrical contact even under demanding conditions. The tin plating process significantly enhances the durability of the component by preventing corrosion, which is essential for maintaining low contact resistance over time. Its precise design facilitates easy installation and ensures a reliable mechanical connection that can withstand vibrations and thermal expansion in various electrical systems.

Suitable for

• Power distribution cabinets and switchgear
• Industrial electrical installations
• Grounding connections
• Heavy-duty machinery wiring
• Automotive and marine electrical systems

When it may not be suitable

This terminal is not intended for use with conductors that do not match the 35 mm² cross-section, as improper sizing can lead to overheating or mechanical failure. It is also not suitable for applications requiring high-temperature insulation or specialized chemical resistance beyond what standard tinned copper provides.

Key specifications

• Material: Tinned copper
• Conductor cross-section: 35 mm²
• Stud hole diameter: 12 mm
• Connection type: Ring terminal

How to use

To install the terminal, first strip the insulation from the end of the 35 mm² cable to the appropriate length. Insert the conductor fully into the barrel of the terminal. Use a professional crimping tool specifically calibrated for 35 mm² terminals to ensure a gas-tight mechanical bond between the wire and the terminal. Once crimped, place the ring over the corresponding 12 mm stud and secure it firmly with a nut and washer to ensure optimal contact pressure.

What to consider before purchase

• Verify the cross-section of your cable matches the 35 mm² specification
• Ensure the stud size of your connection point is 12 mm
• Check that you have the correct crimping tool for this terminal size
• Confirm the environmental conditions are suitable for tinned copper

Usage recommendations

Always ensure the crimping tool is properly maintained and calibrated to the specific terminal size to prevent loose connections or wire damage. Periodically inspect the connection for signs of overheating or corrosion in high-vibration environments.
