Why Choose the Cembre 2509310 Compression Cable Lug?
The Cembre 2509310 is a premium heavy-duty two-hole tin-plated copper compression cable lug engineered to provide secure, low-resistance electrical terminations for 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 2509310 (series reference 2A80-2M12) is manufactured from high-purity annealed electrolytic copper with an electrolytic tin-plated finish to resist atmospheric corrosion. Its double-length 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 copper conductors, the lug features dual M12 fixing holes with 44.5 mm hole centre spacing, making it ideal for switchgear, transformers, substations, industrial control panels, renewable energy systems and heavy-duty power distribution equipment.
