Cembre 2372850 A120-4ESI four-hole electrolytic copper compression cable lug for terminating 630 mm² copper conductors in transformer and industrial power distribution applications.
£67.50
The Cembre 2372850 (A120-4ESI) is a heavy-duty four-hole copper compression cable lug engineered for secure termination of large copper conductors in transformer, switchgear and industrial power distribution applications. As part of the trusted Cembre A-4ESI Series, it is manufactured from high-purity annealed electrolytic copper and electro-tinned to provide outstanding electrical conductivity, corrosion resistance and long-term mechanical reliability.
Designed specifically for transformer and utility applications, the A-4ESI Series incorporates a four-hole fixing arrangement that conforms to Electricity Association (E.A.) specifications, providing superior resistance to vibration, thermal cycling and electrodynamic forces. The extended barrel and inspection hole simplify installation while ensuring a consistently reliable compression crimp.
Designed for terminating 630 mm² copper conductors using a 4-hole ESI transformer fixing pattern, the Cembre 2372850 is ideal for substations, transformers, switchgear, renewable energy installations and industrial power distribution systems requiring secure high-current electrical connections.
Four-hole compression cable lugs provide outstanding mechanical stability by distributing clamping forces across multiple fixing points. When installed using approved Cembre crimping tools and dies, they deliver low-resistance electrical connections capable of withstanding vibration, thermal cycling and demanding operating conditions.
The Cembre A-4ESI Series is widely specified by utilities, transformer manufacturers, OEMs and industrial contractors where dependable high-current cable terminations are essential.
