Why Choose the Cembre 2505030 Copper Compression Lug?
The Cembre 2505030 is a premium heavy-duty tinned copper compression cable lug designed to provide secure, low-resistance electrical terminations for industrial power distribution and medium-voltage applications. Manufactured as the Cembre 2A24-M10, this connector forms part of the trusted 2A-M Heavy Duty series, delivering exceptional electrical conductivity, mechanical strength and long-term reliability for demanding installations.
Manufactured from greater than 99.9% pure annealed electrolytic copper and electrolytically tin plated, the lug provides outstanding conductivity together with excellent corrosion resistance. Its double-length barrel allows multiple compression points for maximum pull-out strength, while the absence of an inspection hole helps prevent moisture ingress, making it suitable for indoor, outdoor and medium-voltage applications up to 35 kV.
Designed for 120 mm² copper conductors with a single M10 fixing hole, the Cembre 2505030 is ideal for substations, transformers, switchgear, motor control centres, industrial control panels and electrical power distribution systems.
