Cembre 2330350 A40-M16 tinned copper compression ring terminal for 185 mm² Class 5 and Class 6 extra-flexible copper conductors with an M16 fixing hole.
£11.20
The Cembre 2330350 A40-M16 is a high-performance copper compression ring terminal designed for terminating extra-flexible copper conductors in demanding electrical installations. Part of the professional Cembre A-M series, it provides a secure, low-resistance connection for switchgear, control panels, welding equipment and industrial power systems.
Manufactured from high-purity electrolytic copper, the terminal is annealed to improve ductility and withstand the mechanical stresses produced during compression crimping. An electrolytic tin-plated finish protects the copper against oxidation and corrosion, helping maintain dependable conductivity throughout the service life of the installation.
The A40-M16 is designed for 185 mm² Class 5 and Class 6 extra-flexible copper conductors and features an M16 fixing hole. Its chamfered barrel entry helps guide fine conductor strands into position, while the integrated inspection hole allows installers to confirm full conductor insertion before crimping.
Extra-flexible conductors contain a high number of fine copper strands and require terminals with barrel dimensions specifically designed for their construction. The Cembre A40-M16 accommodates these conductors while delivering excellent electrical conductivity, mechanical pull-out resistance and dependable performance under vibration.
When installed with compatible Cembre crimping tools and dies, the terminal produces a controlled and repeatable compression connection. Its chamfered entry helps prevent fine strands from bending or spreading during insertion, while the inspection hole provides a clear visual check before the crimping operation begins.
