Why Choose the Cembre 2509980 Heavy Duty Two-Hole Ring Terminal?
The Cembre 2509980 is a premium heavy duty copper compression two-hole ring terminal (type 2A120-2M20) 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 corrosion resistance.
Part of the trusted Cembre 2A-2M Heavy Duty Series, this terminal features a double-length seamless barrel without an inspection hole, improving both electrical and mechanical performance while preventing moisture ingress into the crimped connection. The robust two-hole palm provides superior resistance to vibration and electrodynamic forces, ensuring maximum connection stability in demanding power distribution installations.
Designed for 630 mm² stranded copper conductors (or 500–630 mm² flexible copper conductors) with 2 × M20 fixing holes at 44.5 mm centres, the Cembre 2509980 is ideally suited to substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations up to 35 kV.
