When it may not be suitable
This terminal is specifically designed for 25 mm² conductors and a 6 mm stud size. It is not suitable for wires with different cross-sections or for mounting on studs that do not match the 6 mm specification, as this could lead to poor contact or mechanical failure.
Key specifications
Conductor cross-section: 25 mm²
Stud size: 6 mm
Insulation type: Integrated sleeve
Material: High-conductivity copper with protective coating
How to use
To use the Ergom KOI 25/6, first strip the insulation from the end of your 25 mm² conductor to the appropriate length. Insert the conductor fully into the metal barrel of the terminal. Use a professional-grade crimping tool specifically calibrated for this size to ensure a gas-tight connection. Once crimped, place the ring over the 6 mm stud and secure it firmly with a nut or bolt to complete the installation.
What to consider before purchase
Verify the cross-section of your wire matches the 25 mm² requirement.
Ensure the mounting stud diameter is exactly 6 mm.
Check that you have the correct crimping tool for insulated terminals of this size.
Usage recommendations
Always ensure the power is disconnected before performing any electrical work. Use a calibrated crimping tool to achieve a secure connection and prevent overheating or resistance issues.
