£69.20
The Cembre 2509870 is a premium heavy duty copper compression ring terminal (type 2A120-M16) designed to provide secure, low-resistance electrical connections for demanding industrial, utility and medium-voltage applications. Manufactured from greater than 99.9% pure electrolytic copper with an electrolytically tin-plated finish, it delivers exceptional electrical conductivity together with outstanding resistance to corrosion and oxidation.
As part of the trusted Cembre 2A-M Heavy Duty Series, this terminal incorporates a double-length seamless barrel without an inspection hole, improving both electrical and mechanical performance while preventing moisture ingress into the crimped connection. The annealed copper construction offers excellent ductility, ensuring reliable compression and long-term durability even in vibration-prone installations.
Designed for 630 mm² copper conductors with an M16 fixing stud, the Cembre 2509870 is ideal for substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations operating at voltages up to 35 kV.
Heavy-duty compression lugs provide permanent, low-resistance electrical terminations capable of carrying extremely high current loads while maintaining exceptional mechanical integrity. Their extended barrel construction ensures optimum crimp performance and long-term reliability in demanding industrial environments.
The Cembre 2A-M range is trusted by utilities, OEMs, panel builders and industrial maintenance engineers for substations, transformers, switchgear, grounding systems and medium-voltage cable installations where dependable electrical performance is essential.
