Why Choose the Cembre 2180030 A3-M4 Copper Tube Crimping Lug?
The Cembre 2180030, manufacturer reference A3-M4, is a professional copper tube crimping lug designed for terminating 16 mm² stranded copper conductors onto electrical equipment using an M4 fixing stud. As part of the trusted Cembre A-M series, this non-insulated ring terminal provides a secure, low-resistance electrical connection for industrial control panels, switchgear, machinery and power distribution systems.
Manufactured from high-purity electrolytic copper, the lug is fully annealed to provide optimum ductility during compression. Its electrolytic tin-plated finish helps resist oxidation and corrosion while maintaining excellent electrical conductivity throughout the service life of the installation.
The A3-M4 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. Its compact design makes it ideal for professional electrical installations where reliable terminations are essential.
