£0.58
The Cembre 2180150, manufacturer reference A3-M6, is a premium copper tube crimping lug designed for terminating 16 mm² stranded copper conductors onto electrical equipment using an M6 fixing stud. As part of the proven Cembre A-M series, this non-insulated ring terminal provides a secure, low-resistance electrical connection for industrial power distribution, machinery, switchgear and control panel applications.
Manufactured from high-purity electrolytic copper, the lug is fully annealed to provide optimum ductility during compression. Its electrolytic tin-plated finish protects against oxidation and corrosion while maintaining excellent electrical conductivity throughout the service life of the installation.
The A3-M6 features a chamfered cable entry together with an integrated inspection hole, allowing easy conductor insertion and visual confirmation that the conductor has been fully inserted before crimping. Precision-engineered dimensions ensure dependable electrical performance and excellent resistance to vibration in demanding industrial environments.
Copper tube crimping lugs provide permanent, low-resistance electrical connections between stranded conductors and electrical equipment. When installed using the correct Cembre crimping tool and matching die set, they deliver excellent electrical conductivity together with outstanding resistance to vibration and mechanical stress.
The Cembre A3-M6 combines precision manufacturing, annealed electrolytic copper and a corrosion-resistant tin-plated finish to provide dependable long-term performance across industrial control panels, switchgear, machinery and power distribution systems.
