Cembre 2360850 A80-4ESI four-hole electrolytically tin-plated copper transformer lug for 400 mm² copper conductors.
£49.75
The Cembre 2360850 (A80-4ESI) is a heavy-duty four-hole electrolytic copper compression lug engineered for transformer, switchgear and high-current power distribution applications requiring exceptional mechanical stability. Manufactured from annealed high-conductivity electrolytic copper and electrolytically tin plated, it delivers outstanding electrical performance together with long-term resistance to corrosion and oxidation.
Part of the renowned Cembre A-4ESI Series, this compression terminal is designed for 400 mm² copper conductors and incorporates a four-hole ESI fixing pattern for compatibility with many transformer terminals. The multi-bolt palm provides maximum resistance to vibration, electrodynamic forces and mechanical movement while ensuring an exceptionally secure electrical connection.
Ideal for substations, transformers, switchgear, renewable energy systems and industrial power distribution installations, the Cembre 2360850 delivers reliable, low-resistance cable terminations when installed using compatible professional Cembre compression tooling.
Cembre A-4ESI transformer lugs are manufactured from seamless electrolytic copper tubing to achieve maximum electrical conductivity together with outstanding mechanical strength. The annealed construction ensures optimum ductility during compression, producing secure, vibration-resistant electrical joints with consistently low contact resistance.
The four-hole ESI fixing arrangement provides superior connection stability compared with conventional single-hole terminals, making these lugs ideal for transformer connections and other high-current installations subject to vibration or mechanical stress.
