Why Choose the Cembre 2397320 C300-516 Colour Coded Ring Terminal?
The Cembre 2397320 C300-516 is a premium colour coded copper ring terminal designed for secure, low-resistance electrical connections in industrial control panels, switchgear, machinery and power distribution systems. Manufactured by Cembre, this compression cable lug delivers exceptional conductivity, mechanical strength and long-term reliability for professional electrical installations.
Manufactured from greater than 99.9% pure electrolytic copper, the C300-516 terminal is annealed for improved ductility during crimping and electrolytically tin-plated to provide outstanding resistance to corrosion and oxidation. The chamfered barrel entry and inspection hole simplify conductor insertion while helping ensure correct cable positioning before compression.
Its optimised barrel length allows easy positioning within crimping dies, improving installation speed while producing strong, repeatable electrical terminations. The Cembre C300-516 is ideal for industrial automation, OEM equipment, switchgear assemblies and electrical infrastructure requiring dependable cable connections.
