Cembre 2509670 (2A100-M20) heavy duty electrolytic tin-plated copper compression ring terminal with double-length barrel for 500 mm² copper conductors and M20 stud fixing.
£66.10
The Cembre 2509670 is a premium heavy duty copper compression ring terminal (type 2A100-M20) designed to deliver secure, low-resistance electrical connections for demanding industrial power distribution and medium-voltage installations. Manufactured from greater than 99.9% pure electrolytic copper with an electrolytic tin-plated finish, it provides outstanding conductivity together with long-term protection against corrosion.
As part of the proven Cembre 2A-M Series, this heavy-duty terminal incorporates a double-length seamless barrel without an inspection hole, improving both electrical and mechanical performance while helping prevent moisture ingress. The chamfered barrel entry also simplifies conductor insertion and protects conductor strands during installation.
Designed for 500 mm² copper conductors with an M20 fixing stud, the Cembre 2509670 is ideal for substations, switchgear, transformers, industrial control equipment and medium-voltage cable terminations up to 35 kV.
Heavy-duty compression lugs are engineered to provide permanent, low-resistance electrical terminations capable of carrying high current loads while maintaining excellent mechanical integrity. Their extended barrel design improves crimp quality and ensures dependable long-term performance.
The Cembre 2A-M series is trusted by electrical contractors, panel builders, utilities and industrial maintenance engineers for power distribution, switchgear, transformer and medium-voltage cable installations where reliability is essential.
