£0.62
The Cembre 2170270, manufacturer reference A2-M10, is a high-quality copper tube crimping lug designed for terminating 10 mm² stranded copper conductors onto electrical equipment using an M10 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 power, control and automation applications.
Manufactured from high-purity electrolytic copper, the lug is annealed to provide optimum ductility during compression. The electrolytic tin-plated finish protects against oxidation while maintaining excellent electrical conductivity, ensuring dependable long-term performance in demanding industrial environments.
The A2-M10 features a chamfered cable entry for easy conductor insertion together with an inspection hole that allows installers to verify full cable insertion before crimping. Its compact design makes it suitable for switchgear, electrical panels, machinery, motor control centres and power distribution systems.
Copper tube crimping lugs provide permanent, low-resistance electrical connections between stranded conductors and electrical equipment. When installed using the correct crimping tool and die set, they deliver excellent conductivity together with high resistance to vibration and mechanical stress.
The Cembre A2-M10 combines precision manufacturing with annealed electrolytic copper to provide reliable long-term performance in industrial control panels, switchgear, machinery and power distribution equipment.
