Why Choose the Cembre 2310390 A35-M20 Copper Tube Crimp Lug?
The Cembre 2310390, also identified as the Cembre A35-M20, is a premium non-insulated copper tube ring terminal engineered for terminating 150 mm² Class 5 and Class 6 flexible copper conductors. Designed for demanding industrial electrical installations, it provides a secure connection to an M20 threaded stud while delivering excellent electrical conductivity and long-term mechanical reliability.
Manufactured from over 99.9% pure electrolytic copper, the terminal is annealed to improve compression during crimping and finished with electrolytic tin plating to resist oxidation and corrosion. These characteristics make it ideal for high-current applications requiring dependable, low-resistance electrical connections.
The A35-M20 features a chamfered barrel entry and integrated inspection hole to simplify cable insertion and verify correct conductor positioning before crimping. Its extended barrel design also assists die alignment, enabling faster installation and consistent crimp quality in professional electrical environments.
