Why Choose the Cembre 2290310 A29-M12 Copper Compression Terminal?
The Cembre 2290310 (A29-M12) is a premium copper compression ring terminal designed to provide safe, low-resistance termination of 120 mm² Class 5 and Class 6 flexible copper conductors. Manufactured from annealed electrolytic copper with a purity exceeding 99.9% and finished with electrolytic tin plating, it delivers exceptional electrical conductivity, corrosion resistance and long-term reliability for industrial electrical installations.
Part of the trusted Cembre A-M Series, this non-insulated compression lug features a single M12 fixing hole, a chamfered barrel and an inspection hole that ensures the conductor is fully inserted before crimping. The annealing and electrolytic tinning process improves ductility while increasing resistance to mechanical stress during installation and operation.
Designed for switchgear, control panels, industrial machinery and power distribution systems, the Cembre 2290310 delivers dependable electrical performance wherever professional-grade cable terminations are required.
