2388950 Cembre DR500-12 DIN 46235 COPPER TERMINAL

Why Choose the Cembre 2388950 DR500-12 Copper Tube Crimping Lug?

The Cembre 2388950, manufacturer reference DR500-12, is a professional copper tube compression lug designed for terminating 500 mm² copper conductors onto M12 studs. Part of the established Cembre DR series, this heavy-duty terminal provides a robust connection between very large copper power cables and compatible bolted electrical equipment.

The DR500-12 is manufactured from electrolytic copper and designed for professional compression crimping. Cembre copper lugs use carefully dimensioned tubular construction to provide efficient electrical conductivity and mechanical strength, while annealing supports controlled deformation of the barrel during the crimping process.

With its substantial 500 mm² conductor capacity and M12 connection, the DR500-12 is suitable for high-current power distribution systems, switchgear, transformers and heavy industrial equipment. The copper terminal is electrolytically tin plated to help protect the connection against oxidation and support dependable long-term electrical performance.

Reliable Cable Termination for High-Current Power Connections

Copper tube compression lugs provide a mechanically secure and electrically conductive interface between stranded copper power cables and bolted equipment terminals. During installation, correctly selected professional crimping tooling compresses the tubular barrel around the conductor strands, producing a permanent connection designed to provide efficient conductivity and strong resistance to mechanical pull-out.

For large 500 mm² conductors, correct cable preparation, tooling and die selection are particularly important. Cembre designs its copper terminals as part of a complete crimping system, allowing compatible tooling to produce repeatable compression connections for demanding industrial and power distribution installations.

• High-current industrial switchboards and distribution panels.
• Large busbar and power distribution connections.
• Transformers and power conversion equipment.
• Heavy industrial machinery and large motor installations.
• Generator and electrical power infrastructure connections.
• Commercial, infrastructure and utility power installations.
