Why Choose the Cembre S6-U10/1 Fork Terminal (2164390)?
The Cembre 2164390 (S6-U10/1) is a premium non-insulated copper compression fork terminal designed to provide secure, low-resistance electrical connections for industrial and commercial applications. Manufactured from 99.95% pure electrolytic copper with a high-quality electrolytic tin-plated finish, it delivers excellent electrical conductivity, corrosion resistance and long-term reliability.
Designed for professional electricians, panel builders and OEM machine manufacturers, the S6-U10/1 features a brazed seam barrel with an internal knurled surface to maximise conductor retention and ensure a consistently reliable crimp. Suitable for 4–6 mm² copper conductors, it accommodates an M10 fixing stud with an enlarged fork profile, making it ideal for industrial control panels, machinery, automation systems and power distribution equipment.
Its fork design allows conductors to be installed or removed without fully removing the fixing screw, reducing maintenance time while maintaining a secure electrical connection in demanding industrial environments.
