Cembre 2397340 C300-38 white colour-coded copper compression ring terminal for 300 kcmil copper conductors, featuring a 3/8-inch fixing hole, inspection hole and tin-plated finish.
£14.20
The Cembre 2397340, manufacturer reference C300-38, is a professional colour-coded copper ring terminal designed to create secure electrical connections on copper power conductors. Part of the established Cembre C series, this non-insulated compression lug combines high electrical conductivity with the mechanical strength required for dependable power distribution and industrial wiring installations.
Manufactured from high-purity electrolytic copper tube, the C300-38 is annealed to provide the ductility required during compression. This helps the terminal withstand the deformation produced by crimping while reducing the risk of cracking between the barrel and palm. An electrolytic tin-plated finish also provides protection against oxidation and supports long-term connection reliability.
The terminal is designed for 300 kcmil copper conductors and incorporates a 3/8-inch fixing hole, equivalent to approximately 10 mm. Its white colour code assists conductor and die identification, while the inspection hole allows installers to confirm that the cable has been inserted fully before crimping.
Compression cable lugs provide a permanent electrical and mechanical connection between a conductor and equipment such as busbars, switchgear, transformers and distribution assemblies. When installed using a compatible Cembre crimping tool and the specified die set, the terminal barrel is compressed around the conductor to create a low-resistance connection.
The Cembre C series is engineered for reliable performance where connections may be exposed to vibration, conductor movement and changing electrical loads. Its annealed copper construction, tin-plated finish and colour-coded identification make the C300-38 suitable for professional installation, maintenance and panel-building applications.
