Cembre 2320070 A37-M8 non-insulated electrolytic tin-plated copper tube ring terminal for 185 mm² Class 5 and Class 6 flexible copper conductors with an M8 stud connection.
£7.65
The Cembre 2320070, also known as the Cembre A37-M8, is a premium non-insulated copper tube ring terminal designed for terminating 185 mm² Class 5 and Class 6 flexible copper conductors. Manufactured for demanding industrial power applications, it provides a secure connection between large cross-section conductors and an M8 threaded stud.
Manufactured from high-purity electrolytic copper and finished with electrolytic tin plating, the terminal delivers outstanding electrical conductivity while providing excellent resistance to corrosion and oxidation. Annealing improves crimp quality and mechanical strength, ensuring dependable long-term performance.
The A37-M8 features a chamfered cable entry and integrated inspection hole, allowing easy conductor insertion and visual confirmation before crimping. Its extended barrel simplifies positioning within crimping dies, making installation faster and more reliable for professional electrical contractors and panel builders.
The Cembre A37-M8 is engineered to produce low-resistance, mechanically secure electrical terminations for high-current industrial applications. When installed using the recommended Cembre crimping tools and dies, it provides uniform compression, excellent conductivity and dependable long-term reliability.
Its larger barrel is specifically designed for highly flexible copper conductors used throughout switchgear, industrial control panels, generators, renewable energy systems and heavy-duty machinery where reliable electrical connections are essential.
