Cembre 2509780 (2A100-2M16) heavy duty electrolytically tin-plated copper compression two-hole ring terminal for 500 mm² copper conductors with dual M16 fixing.
£82.40
The Cembre 2509780 is a premium heavy duty copper compression two-hole ring terminal (type 2A100-2M16) designed to provide secure, low-resistance electrical connections for demanding industrial power distribution and medium-voltage installations. Manufactured from high-purity electrolytic copper with an electrolytically tin-plated finish, it offers outstanding electrical conductivity together with long-term protection against corrosion.
Part of the proven Cembre 2A-2M Heavy Duty Series, this terminal features a double-length seamless barrel without an inspection hole to maximise electrical and mechanical performance while preventing moisture ingress. Its two-hole palm provides superior stability and resistance to vibration, making it ideal for critical power applications requiring dependable long-term performance.
Designed for 500 mm² copper conductors with dual M16 fixing holes, the Cembre 2509780 is ideally suited to substations, transformers, switchgear, industrial control panels and medium-voltage cable installations up to 35 kV.
Heavy-duty compression lugs provide permanent, low-resistance electrical connections capable of carrying very high current loads while maintaining excellent mechanical integrity. The two-hole fixing design offers superior resistance to vibration and rotation compared with conventional single-hole terminals.
The Cembre 2A-2M series is trusted by utilities, OEMs, panel builders and industrial maintenance engineers for demanding power distribution, transformer, switchgear and medium-voltage cable applications where reliability is essential.
