£9.56
The Cembre 2320150, also identified as the Cembre A37-M12, is a premium non-insulated copper tube ring terminal designed for terminating 185 mm² Class 5 and Class 6 flexible copper conductors. As part of Cembre's professional A-M Copper Tube Crimping Lug Series, it provides a secure, low-resistance electrical connection to an M12 threaded stud for demanding industrial power applications.
Manufactured from over 99.9% pure electrolytic copper, the terminal is annealed to improve ductility during crimping and electro-tin plated to provide outstanding protection against corrosion and oxidation. This combination ensures reliable conductivity, excellent mechanical strength and long service life even in demanding environments.
The A37-M12 features a chamfered cable entry and integrated inspection hole, allowing quick conductor insertion and visual confirmation before crimping. Its extended barrel design assists accurate positioning within crimping dies, helping installers achieve consistent, high-quality terminations.
The Cembre A37-M12 is engineered to deliver secure, low-resistance electrical terminations for demanding industrial applications. When installed using the recommended Cembre crimping tools and dies, it provides consistent compression, excellent electrical conductivity and outstanding mechanical retention.
Its enlarged barrel accommodates highly flexible copper conductors commonly used throughout switchgear, industrial control panels, generators, renewable energy systems, battery installations and heavy-duty machinery where dependable high-current electrical connections are essential.
