Why Choose the Cembre 2509989 Heavy Duty Ring Terminal?
The Cembre 2509989 is a premium heavy duty copper compression ring terminal (type 2A200-M20) engineered 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 provides excellent ductility, ensuring reliable compression and long service life in demanding environments.
Designed for 1000 mm² stranded copper conductors (or 800 mm² flexible copper conductors) with an M20 fixing stud, the Cembre 2509989 is ideal for substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations operating at voltages up to 35 kV.
