Why Choose the Cembre 2509850 Heavy Duty Ring Terminal?
The Cembre 2509850 is a premium heavy duty copper compression ring terminal (type 2A120-M12) engineered to provide secure, low-resistance electrical connections for high-current industrial and medium-voltage applications. Manufactured from high-purity annealed electrolytic copper with an electrolytically tin-plated finish, it offers excellent conductivity together with outstanding corrosion resistance for long service life.
As part of the renowned 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 long-barrel design provides superior pull-out strength and reliable operation in demanding industrial environments.
Designed for 630 mm² copper conductors with an M12 fixing stud, the Cembre 2509850 is ideally suited to substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations operating up to 35 kV.
