## Summary description

The Erko KCS90 is a high-quality copper tubular ring terminal designed for reliable electrical connections. Featuring a 90-degree angled design, it is suitable for 10mm² conductors and an M12 stud size. This terminal ensures excellent conductivity and mechanical strength, making it ideal for professional electrical installations, power distribution systems, and industrial wiring applications where space-saving angled connections are required.

## Long description

The Erko KCS90 is a high-quality copper tubular ring terminal engineered for secure and efficient electrical terminations. Designed with a 90-degree angle, this terminal is specifically crafted to facilitate connections in confined spaces where standard straight terminals may not be practical. It is compatible with 10mm² conductors and features an M12 stud hole, ensuring a precise fit for various electrical hardware and busbars.
Advantages
The primary benefit of the Erko KCS90 lies in its robust construction from high-grade copper, which provides superior electrical conductivity and minimizes resistance at the connection point. The tubular design allows for a strong crimp, ensuring mechanical stability and long-term reliability under varying thermal conditions. Its 90-degree bend is an essential feature for professional installers who need to manage cable routing in tight enclosures or panels, effectively reducing strain on the conductor and preventing cable damage.
Suitable for
Professional electrical installations
Power distribution systems
Industrial wiring applications
Control panels and switchgear
This terminal may not be suitable for applications involving conductors outside the 10mm² specification, as an improper fit can lead to high resistance or mechanical failure. It is also not intended for use in environments where the material is exposed to highly corrosive substances that could degrade the copper surface over time.
Key specifications
Material: High-quality copper
Conductor cross-section: 10mm²
Stud size: M12
Angle: 90 degrees
Type: Tubular ring terminal
To use the Erko KCS90, first strip the insulation from the end of the 10mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Using a compatible crimping tool, apply sufficient pressure to the barrel to create a permanent, gas-tight connection. Once crimped, the terminal can be secured to the M12 stud using a corresponding nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.
What to consider before purchase
Verify the conductor cross-section matches the 10mm² requirement
Ensure the M12 stud size is compatible with your equipment
Confirm that the 90-degree angle is appropriate for your specific cable routing needs
Check that you have the correct crimping tool for tubular copper terminals
Usage recommendations
Always ensure the conductor is clean and free of oxidation before crimping to maintain optimal electrical contact. Periodically inspect the connection for signs of overheating or loosening in high-vibration environments.
