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.
£63.90
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.
Compression cable lugs provide permanent, low-resistance electrical terminations between conductors and electrical equipment. When installed using approved compression tooling, they maximise current transfer, minimise voltage drop and provide exceptional long-term mechanical performance.
The Cembre 2A-2M Heavy Duty range incorporates a robust two-hole palm that improves alignment and resistance to vibration, making these connectors particularly suitable for substations, switchgear, grounding systems and other critical electrical infrastructure.
