Cembre 2509982 (2A160-2M16) heavy-duty electrolytic copper compression two-hole ring terminal for 630 mm² flexible or 800 mm² stranded conductors with dual M16 fixing holes.
£171.80
The Cembre 2509982, also identified as 2A160-2M16, is a premium heavy-duty copper compression two-hole ring terminal engineered for terminating very large copper conductors in demanding industrial power distribution and utility applications. Manufactured from high-purity electrolytic copper with an electrolytically tin-plated finish, it delivers exceptional electrical conductivity, outstanding corrosion resistance and long-term mechanical reliability.
As part of the trusted Cembre 2A-2M Heavy Duty Series, this terminal features a double-length seamless barrel without an inspection hole, improving both electrical and mechanical performance while preventing moisture ingress into the crimped connection. The two-hole palm provides superior resistance to vibration and electrodynamic forces, making it ideal for critical high-current installations.
Designed for 630 mm² flexible or 800 mm² stranded copper conductors with 2 × M16 fixing holes, the 2A160-2M16 is ideally suited to substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations operating up to 35 kV.
Heavy-duty copper compression terminals are designed to provide permanent, low-resistance electrical connections while maintaining exceptional mechanical integrity under very high current loads. Their extended barrel construction ensures optimum crimp performance, while the two-hole fixing arrangement provides excellent resistance to vibration, rotation and electrodynamic stress.
The Cembre 2A-2M range combines annealed electrolytic copper with electrolytic tin plating to provide dependable long-term performance in demanding indoor and outdoor electrical installations. The seamless barrel without an inspection hole further improves environmental protection by reducing moisture ingress into the crimped connection.
