Why Choose the Cembre 2509930 Heavy Duty Two-Hole Ring Terminal?
The Cembre 2509930 is a premium heavy duty copper compression two-hole ring terminal (type 2A120-2M14) engineered for secure, low-resistance electrical connections in demanding industrial, utility and medium-voltage applications. Manufactured from greater than 99.9% pure electrolytic copper and electrolytically tin-plated, it provides excellent electrical conductivity together with outstanding protection against corrosion and oxidation.
Part of the proven Cembre 2A-2M Heavy Duty Series, this terminal incorporates a double-length seamless barrel without an inspection hole, maximising both electrical and mechanical performance while preventing moisture ingress. The two-hole palm provides increased resistance to vibration and rotation, making it ideal for critical power applications where connection stability is essential.
Designed for 630 mm² copper conductors with dual M14 fixing holes, the Cembre 2509930 is ideally suited to substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations operating up to 35 kV.
