Ergom KOR 25/8 Tinned Copper Ring Terminal

The Ergom KOR 25/8 tinned copper ring terminal is a professional-grade component designed to provide secure and efficient electrical connections for 25 mm² conductors. Manufactured from high-quality copper and finished with a tin coating, this terminal offers superior electrical conductivity while protecting the connection against oxidation and environmental corrosion. Its robust construction ensures long-term reliability in demanding electrical systems.

Advantages

The primary benefit of the Ergom KOR 25/8 terminal is its high-purity copper base, which minimizes electrical resistance and prevents overheating at the connection point. The tin plating significantly enhances durability, making it suitable for use in environments where moisture or chemical exposure might otherwise degrade standard copper components. The ring design provides a stable, vibration-resistant contact surface that remains securely fastened to the stud, ensuring consistent performance over time.

Suitable for

• Power distribution panels and switchgear
• Industrial machinery and automation wiring
• Automotive and marine electrical systems
• Grounding connections in electrical installations

When it may not be suitable

This terminal is specifically designed for 25 mm² conductors and an 8 mm stud size. It is not suitable for cables with different cross-sections, as an improper fit can lead to poor electrical contact, increased resistance, and potential fire hazards. It should also not be used in applications requiring high-temperature resistance beyond the limits of standard tinned copper.

Key specifications

• Conductor cross-section: 25 mm²
• Stud hole diameter: 8 mm
• Material: Tinned copper
• Connection type: Ring terminal

How to use

To install the terminal, first strip the insulation from the end of the 25 mm² cable to the appropriate length. Insert the conductor fully into the barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for 25 mm² terminals to ensure a gas-tight mechanical connection. Once crimped, place the ring over the 8 mm stud and tighten the nut securely to ensure optimal contact pressure.

What to consider before purchase

• Verify that your cable cross-section is exactly 25 mm²
• Ensure the mounting stud diameter is 8 mm
• Check that you have the correct crimping tool for this terminal size
• Confirm the environmental conditions are compatible with tinned copper

Usage recommendations

Always ensure the crimping tool is properly maintained and calibrated to the terminal size to prevent loose connections or damage to the conductor strands.
