£23.60
The Cembre 2506390, also identified as 2A30-2M10, is a premium heavy-duty copper compression ring terminal designed for terminating large copper conductors in demanding industrial power distribution systems. Manufactured from high-purity electrolytic copper with a durable electro-tinned finish, it provides excellent electrical conductivity, corrosion resistance and long-term reliability in industrial environments.
As part of Cembre's 2A-2M heavy-duty terminal series, this connector features a two-hole palm for increased mechanical stability and improved resistance to vibration and electrodynamic forces. Its long compression barrel without an inspection hole helps prevent moisture ingress while maximising crimp performance.
Designed for industrial switchgear, transformers, substations, grounding systems and power distribution equipment, the 2A30-2M10 provides dependable low-resistance conductor terminations suitable for demanding low and medium-voltage applications when installed using compatible Cembre crimping tools.
Heavy-duty copper compression terminals are engineered to deliver dependable low-resistance electrical connections while withstanding high mechanical loads, vibration and thermal cycling. Their robust construction makes them ideal for demanding industrial power installations where long-term reliability is essential.
The Cembre 2A-2M range combines annealed electrolytic copper with electrolytic tin plating to improve crimp performance, corrosion resistance and service life in indoor and outdoor applications. The two-hole palm provides additional fixing security for critical electrical connections.
