2509346 Cembre 2A80-2M14/55Deg COPPER TERMINAL
Cembre 2509346 (2A80-2M14/55) heavy-duty electro-tinned copper two-hole compression cable lug for 400 mm² stranded copper conductors with dual M14 fixing holes at 55 mm centres.
Why Choose the Cembre 2509346 Compression Cable Lug?
The Cembre 2509346 is a premium heavy-duty two-hole tin-plated copper compression cable lug engineered for secure, low-resistance electrical terminations in demanding industrial, utility and medium-voltage power applications. Manufactured by Cembre, this high-performance connector delivers exceptional electrical conductivity, outstanding mechanical strength and long-term reliability for critical electrical installations.
Part of the trusted Cembre 2A-2M Heavy Duty series, the 2509346 (series reference 2A80-2M14/55) is manufactured from high-purity annealed electrolytic copper with an electrolytic tin-plated finish to resist atmospheric corrosion. Its extended barrel maximises conductor contact while the two-hole palm provides excellent resistance to vibration and electrodynamic forces. The closed-end design without an inspection hole prevents moisture ingress, making it ideal for indoor and outdoor installations up to 35 kV.
Designed for 400 mm² stranded copper conductors (also suitable for 300–400 mm² flexible conductors), the lug features dual M14 fixing holes with a 55 mm hole centre spacing, making it ideal for switchgear, transformers, substations, industrial control panels, renewable energy systems and heavy-duty power distribution equipment.
