£97.30
The Cembre 2509910 is a premium heavy duty copper compression two-hole ring terminal (type 2A120-2M12) engineered to deliver secure, low-resistance electrical connections for demanding industrial, utility and medium-voltage applications. Manufactured from high-purity annealed electrolytic copper with an electrolytically tin-plated finish, it provides exceptional electrical conductivity together with outstanding corrosion resistance for long service life.
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 offers increased resistance to vibration and rotation, making it ideal for critical power installations requiring maximum connection stability.
Designed for 630 mm² copper conductors with dual M12 fixing holes, the Cembre 2509910 is ideally suited to substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations operating 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. The two-hole fixing design provides superior resistance to vibration and rotational movement, ensuring reliable long-term performance in demanding electrical installations.
The Cembre 2A-2M 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.
