£21.20
The Cembre 2320910, also identified as the Cembre A37-2M12, is a premium double-hole non-insulated copper tube ring terminal designed for terminating 185 mm² Class 5 and Class 6 flexible copper conductors. Part of Cembre's professional A-2M Series, this terminal features two M12 fixing holes to provide exceptional mechanical stability, making it ideal for demanding industrial power distribution and switchgear applications.
Manufactured from high-purity annealed electrolytic copper, the terminal is electrolytically tin plated to provide excellent resistance against corrosion and oxidation while maintaining outstanding electrical conductivity. The double-hole palm prevents rotation during service, helping maintain a secure, low-resistance electrical connection throughout the installation's lifetime.
The A37-2M12 incorporates a chamfered cable entry and integrated inspection hole, allowing easy conductor insertion and visual confirmation before crimping. Its extended barrel design enables accurate positioning within compatible Cembre crimping dies, ensuring fast, repeatable and professional installations.
The Cembre A37-2M12 is engineered for applications where electrical performance and mechanical stability are equally important. Its twin-hole palm design distributes clamping forces evenly while preventing movement caused by vibration or electrodynamic forces, making it ideal for critical power distribution installations.
When installed using compatible Cembre crimping tools and dies, the terminal delivers consistent compression, excellent conductivity and dependable long-term reliability in switchgear, industrial machinery, transformers and renewable energy systems.
