Why Choose the Cembre A40-M12 Copper Crimp Lug?
The Cembre 2330270 A40-M12 is a high-quality copper compression ring terminal designed for reliable termination of extra-flexible copper conductors in industrial electrical systems. Part of the professional Cembre A-M terminal series, it provides excellent electrical conductivity and mechanical strength for demanding panel, switchgear and power distribution applications.
Manufactured from electrolytic copper with a purity greater than 99.9%, the terminal is annealed to provide optimum ductility during compression crimping. Its electrolytically tin-plated finish protects the copper against oxidation and corrosion, helping maintain dependable electrical performance throughout the service life of the connection.
The A40-M12 is designed for 185 mm² highly flexible Class 5 and Class 6 copper conductors and features an M12 fixing hole. Its chamfered barrel entry helps guide fine conductor strands into the terminal, while the integrated inspection hole allows installers to confirm complete conductor insertion before crimping.

Reliable Termination for Extra-Flexible Conductors
Extra-flexible conductors contain a large number of fine copper strands and require terminals with barrel dimensions suited to their construction. The Cembre A40-M12 is specifically engineered to accommodate these conductors while supporting efficient electrical conductivity and strong resistance to vibration and pull-out forces.
The terminal should be installed using compatible Cembre crimping tools and dies to produce a controlled, repeatable compression. Its long barrel supports accurate positioning within the crimping dies, while the inspection hole helps technicians verify that the conductor is fully inserted before the crimping cycle begins.
