## Summary description

The Erko KCS90 is a high-quality tubular ring terminal made of copper, designed for 120mm² conductors. Featuring a 90-degree angled design and a 12mm mounting hole, this terminal ensures reliable electrical connections in power distribution and industrial wiring systems. Its robust construction provides excellent conductivity and durability for demanding electrical installations.

## Long description

The Erko KCS90 Copper Tubular Ring Terminal is a professional-grade electrical component engineered for secure and efficient cable termination. Designed specifically for 120mm² conductors, this terminal features a 90-degree angled geometry, allowing for optimal cable routing in confined spaces or complex electrical panels. Its tubular construction ensures a high-pressure, low-resistance connection, making it an essential part of power distribution and industrial wiring infrastructure.
Advantages
The primary benefit of the Erko KCS90 is its superior conductivity, achieved through the use of high-quality copper material that minimizes energy loss and heat generation. The 90-degree angle design significantly improves installation flexibility, reducing mechanical stress on the cable and preventing sharp bends that could compromise the integrity of the conductor. Furthermore, the robust build quality ensures long-term reliability in demanding environments, providing a stable connection that resists vibration and thermal expansion.
Suitable for
Power distribution cabinets and switchgear
Industrial machinery and heavy-duty electrical systems
Connecting large-gauge cables to busbars or terminal blocks
Electrical installations requiring space-saving cable management
When it may not be suitable
This terminal is not intended for use with aluminum conductors, as direct contact can lead to galvanic corrosion. It is also not suitable for applications where the mounting bolt size differs significantly from the 12mm hole diameter, as this may result in an insecure mechanical connection.
Key specifications
Material: High-conductivity copper
Conductor cross-section: 120mm²
Mounting hole diameter: 12mm
Angle: 90 degrees
Type: Tubular ring terminal
How to use
To install the Erko KCS90, first strip the insulation from the end of the 120mm² copper cable to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional hydraulic or mechanical crimping tool compatible with the terminal size to perform a secure crimp. Ensure the crimping die matches the terminal specifications to achieve a gas-tight connection. Once crimped, mount the terminal onto the desired contact point using a 12mm bolt, ensuring the connection is tightened to the manufacturer's specified torque.
What to consider before purchase
Verify the cross-section of your cable matches the 120mm² specification
Ensure the mounting surface accommodates a 12mm bolt
Check that the 90-degree angle is appropriate for your specific cable routing needs
Confirm that your crimping tool is compatible with tubular copper terminals
Usage recommendations
Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid reusing terminals once they have been crimped, as the material deformation during the initial installation compromises the mechanical strength of the bond.
