## Long description

The Ergom KOI 25/10 is a high-quality insulated ring terminal designed to provide secure and reliable electrical connections for professional wiring projects. Engineered specifically for 25 mm² wire cross-sections and featuring a 10 mm stud hole, this terminal ensures optimal electrical conductivity and long-term mechanical stability. It serves as a critical component in both industrial and residential electrical systems, offering robust insulation that protects against short circuits and environmental factors.
Advantages
This ring terminal is manufactured to high standards, ensuring a consistent and durable connection that resists vibration and mechanical stress. The integrated insulation sleeve provides an essential layer of safety, reducing the risk of accidental contact and short circuits in crowded electrical panels. Its design facilitates efficient installation, allowing for a firm grip on the conductor while maintaining excellent contact surface area for reliable power transmission.
Suitable for
Industrial electrical control panels
Residential power distribution systems
Automotive and marine electrical wiring
Grounding connections in heavy machinery
When it may not be suitable
This terminal is not intended for use with wire sizes other than 25 mm² or stud sizes that do not match the 10 mm specification, as improper sizing can lead to loose connections and overheating. It is also not suitable for applications requiring high-temperature resistance beyond the limits of standard insulation materials.
Key specifications
Wire cross-section: 25 mm²
Stud hole diameter: 10 mm
Insulation type: Integrated sleeve
Material: High-conductivity copper with protective plating
How to use
To use the Ergom KOI 25/10, first strip the insulation from the end of your 25 mm² wire to the appropriate length. Insert the conductor into the barrel of the terminal and use a professional-grade crimping tool designed for insulated terminals to create a secure mechanical bond. Once crimped, place the ring over the corresponding 10 mm stud and tighten the nut or bolt firmly to ensure a stable electrical connection.
What to consider before purchase
Verify that your wire gauge is exactly 25 mm²
Ensure the mounting stud diameter is 10 mm
Check that your crimping tool is compatible with insulated ring terminals of this size
Usage recommendations
Always ensure that the crimping tool is fully closed during the installation process to achieve a gas-tight connection, which prevents oxidation and ensures maximum electrical efficiency over time.
