£44.00
The Cembre 2370110 (A100-M20) is a premium electrolytic copper tube crimp lug designed to provide secure, low-resistance terminations for large copper conductors in demanding industrial and power distribution applications. Manufactured from annealed electrolytic copper with a purity exceeding 99.9% and finished with an electrolytic tin-plated coating, it delivers outstanding electrical conductivity, superior mechanical strength and long-term corrosion resistance.
Part of the trusted Cembre A-M Series, this compression terminal is designed for 500 mm² copper conductors (or 400 mm² flexible conductors) and features a robust M20 stud connection. The chamfered barrel entry, inspection hole and extended barrel simplify installation while ensuring consistently high-quality compression crimps.
Ideal for switchgear, substations, transformers, industrial control panels and renewable energy installations, the Cembre 2370110 provides dependable electrical terminations when installed using compatible professional hydraulic compression crimping tools.
Cembre A-M Series compression lugs are manufactured from seamless electrolytic copper tubing to achieve exceptional electrical conductivity together with excellent mechanical strength. The annealed construction enables optimum deformation during crimping, producing secure electrical joints with consistently low contact resistance.
The electrolytic tin-plated finish protects the connector against corrosion while the chamfered barrel entry and inspection hole simplify installation by ensuring complete conductor insertion before compression. These features make the A100-M20 ideal for demanding industrial and utility applications.
