## Summary description

The Ergom KOI 25/8 is a high-quality insulated ring terminal designed for reliable electrical connections. It is suitable for 25 mm² conductors with an 8 mm stud size. This terminal ensures secure contact and protection against short circuits in various electrical installations, control panels, and wiring systems, providing durability and ease of installation for professional electrical work.

## Long description

The Ergom KOI 25/8 insulated ring terminal is a professional-grade electrical component engineered for secure and reliable wire terminations. Designed specifically for conductors with a cross-section of 25 mm², this terminal features an 8 mm stud hole, making it compatible with a wide range of standard electrical hardware. The integrated insulation provides essential protection against accidental short circuits and enhances the safety of electrical connections in demanding environments.
Advantages
This ring terminal offers exceptional mechanical strength and electrical conductivity, ensuring long-term stability for your wiring systems. The high-quality insulation material is designed to withstand standard operating conditions, providing a robust barrier that prevents contact between adjacent terminals. Its design facilitates efficient installation, allowing for quick and precise crimping onto the conductor, which saves time during assembly and maintenance tasks in control panels or industrial equipment.
Suitable for
Electrical control panels and switchgear
Industrial wiring systems
Power distribution units
Automotive and marine electrical installations
General electrical maintenance and repair
When it may not be suitable
This terminal is not intended for use with conductors that fall outside the specified 25 mm² cross-section range, as improper sizing can lead to loose connections or overheating. It is also not suitable for environments where exposure to extreme chemical agents or temperatures exceeds the rated capacity of the insulation material.
Key specifications
Conductor cross-section: 25 mm²
Stud size: 8 mm
Insulation type: Integrated sleeve
Material: High-conductivity copper with protective coating
How to use
To install the Ergom KOI 25/8, first strip the insulation from the end of the 25 mm² conductor to the appropriate length. Insert the exposed wire fully into the barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for insulated terminals of this size to compress the barrel securely onto the wire. Ensure the crimp is tight and that no individual wire strands are protruding before mounting the ring onto the 8 mm stud and tightening the nut to ensure a solid electrical connection.
What to consider before purchase
Verify the conductor cross-section matches the 25 mm² requirement
Ensure the stud diameter is exactly 8 mm for a proper fit
Confirm that your crimping tool is compatible with insulated ring terminals
Check the environmental conditions of the installation site
Usage recommendations
Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid reusing terminals once they have been crimped, as this may compromise the mechanical and electrical performance of the joint.
