£0.55
The Cembre 2163930 (S6-M14) is a premium non-insulated copper compression ring terminal designed to provide secure, low-resistance electrical terminations for industrial and commercial wiring applications. Manufactured from high-purity electrolytic copper with a durable electrolytic tin-plated finish, it offers excellent conductivity, corrosion resistance and dependable long-term performance.
Designed for professional electricians, panel builders and OEM machine manufacturers, the S6-M14 features a brazed seam barrel with internal knurling to maximise conductor retention and ensure a consistent, high-quality crimp. Suitable for 4–6 mm² copper conductors, it provides a secure bolted connection using an M14 fixing stud.
Its robust construction makes it ideal for electrical control panels, switchgear, machinery, motor control centres and power distribution equipment where reliable cable terminations are essential.
Compression ring terminals provide permanent, vibration-resistant cable terminations with exceptionally low electrical resistance. When installed using the correct crimping dies and tooling, they deliver dependable long-term electrical and mechanical performance in demanding industrial environments.
Cembre's S Series terminals combine precision manufacturing, high-purity electrolytic copper and corrosion-resistant tin plating to ensure reliable cable terminations for machinery, automation systems, switchgear and power distribution equipment.
