Why Choose the Cembre 2509628 Compression Cable Lug?
The Cembre 2509628 is a premium heavy-duty 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-M Heavy Duty series, the 2509628 (series reference 2A100-M14) 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 closed-end design without an inspection hole helps prevent moisture ingress, making it suitable for indoor and outdoor installations and medium-voltage systems up to 35 kV.
Designed for 500 mm² copper conductors (also suitable for 400–500 mm² flexible conductors), the lug features a single M14 fixing hole, making it ideal for switchgear, transformers, substations, industrial control panels, renewable energy systems and heavy-duty power distribution equipment.
