Ergom KOI 25/8 Insulated Ring Terminal

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.
