Why Choose the Cembre 2504350 Copper Compression Lug?
The Cembre 2504350 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 2A19-M20, this connector forms part of the proven 2A-M Heavy Duty series, delivering outstanding 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 exceptional conductivity together with excellent resistance to corrosion. Its extended barrel allows multiple compression points for maximum mechanical strength, while the absence of an inspection hole helps prevent moisture ingress, making it ideal for indoor, outdoor and medium-voltage installations up to 35 kV.
Designed for 95 mm² copper conductors with a single M20 fixing hole, the Cembre 2504350 is ideal for substations, transformers, switchgear, motor control centres, industrial control panels and electrical power distribution systems.
Manufactured from high-purity annealed electrolytic copper.
Electro-tin plated for superior corrosion resistance.
Suitable for industrial and medium-voltage applications up to 35 kV.
