Cembre 2500030 2A3-M8 heavy-duty electrolytic copper compression ring terminal with long barrel and M8 stud hole for 16 mm² copper conductors.
£1.46
The Cembre 2500030 (2A3-M8) is a premium heavy-duty copper compression ring terminal engineered for secure cable termination in industrial power distribution, switchgear, grounding systems and medium-voltage installations. Manufactured from greater than 99.9% purity electrolytic copper and electro-tin plated, it delivers outstanding electrical conductivity, corrosion resistance and long-term mechanical performance.
As part of the renowned Cembre 2A-M Series, this long-barrel terminal is specifically designed for demanding applications where maximum electrical and mechanical integrity is required. The annealed copper construction provides optimum ductility during compression, while the seamless barrel design without an inspection hole helps prevent moisture ingress, making it suitable for indoor, outdoor and medium-voltage installations up to 35 kV.
Designed for 16 mm² copper conductors with an M8 fixing hole, the Cembre 2500030 is widely used by panel builders, electrical contractors, utilities and industrial maintenance engineers where dependable heavy-duty cable termination is essential.
Heavy-duty compression terminals provide secure, low-resistance electrical connections while delivering exceptional mechanical strength. Manufactured from annealed electrolytic copper and protected with electro-tin plating, the Cembre 2A-M Series provides reliable long-term performance in industrial power and grounding applications.
The long barrel construction provides increased conductor contact area and enhanced pull-out strength, making the terminal particularly suitable for demanding installations subject to vibration, mechanical loading and harsh environmental conditions.
