£1.54
The Cembre 2210310, also identified as A9-M12, is a premium tinned copper compression ring terminal designed for secure, low-resistance termination of 35 mm² Class 5 and Class 6 flexible copper conductors. Manufactured by Cembre, it delivers outstanding electrical performance, mechanical strength and long-term reliability for industrial power and control applications.
Manufactured from annealed, high-purity electrolytic copper and electro-tin plated to resist corrosion and oxidation, the A9-M12 is engineered for optimum conductivity and durability. The chamfered barrel and integrated inspection hole simplify conductor insertion and help ensure a correct compression crimp using compatible Cembre tooling.
Designed for 35 mm² flexible copper conductors with an M12 stud connection, the Cembre 2210310 is ideal for switchgear, control panels, industrial machinery, motor control centres and power distribution systems requiring dependable bolted electrical connections.
Compression ring terminals provide permanent, low-resistance electrical joints capable of withstanding vibration, thermal cycling and demanding industrial operating conditions. Correctly crimped terminals improve electrical reliability while reducing maintenance requirements.
The Cembre A-M series has been specifically developed for highly flexible copper conductors used throughout industrial automation, machinery manufacturing, switchgear construction and electrical panel assembly.
