Why Choose the Cembre 2396940 C4/0-34 Colour-Coded Copper Crimping Lug?
The Cembre 2396940, manufacturer reference C4/0-34, is a high-quality colour-coded copper crimping lug designed for secure termination of large copper conductors in industrial electrical installations, power distribution systems and control equipment. Manufactured as part of the Cembre C series, this compression lug combines excellent electrical conductivity with dependable mechanical strength.
The lug is manufactured from high-purity electrolytic copper and is annealed to improve ductility during crimping. An electrolytic tin-plated finish helps protect the connector against oxidation, supporting reliable long-term electrical performance in demanding environments. Its chamfered barrel entry and inspection hole simplify conductor insertion and allow installers to confirm that the cable has been fully positioned before crimping.
Designed for 110 mm² copper conductors, the C4/0-34 features a 21 mm palm hole suitable for M20 fixings. The purple colour-coded die marking and Cembre die index 19 help installers select the correct tooling and achieve a consistent, accurately compressed connection.

Reliable High-Current Electrical Connections
Compression cable lugs provide a secure electrical and mechanical connection between conductors and equipment terminals. When installed using the correct Cembre crimping tool and die set, the C4/0-34 creates a low-resistance joint capable of withstanding vibration, mechanical stress and demanding industrial operating conditions.
The colour-coded die marking system helps reduce installation errors by making it easier to identify the correct compression tooling. The annealed copper barrel deforms evenly during crimping, while the tin-plated surface helps preserve conductivity by protecting the copper against oxidation.
Typical Applications
- Industrial power distribution panels.
- Switchgear and electrical control cabinets.
- Transformer and generator connections.
- Motor control centres and large motor feeders.
- Renewable energy and battery installations.
- Railway and transport electrical systems.
- Utility and infrastructure projects.
- Heavy machinery and manufacturing equipment.
