2388980 Cembre DR500-20 DIN 46235 COPPER TERMINAL
Cembre 2388980 DR500-20 is a tin-plated electrolytic copper compression lug designed for terminating 500 mm² copper conductors onto M20 electrical connections.
Why Choose the Cembre 2388980 DR500-20 Copper Tube Crimping Lug?
The Cembre 2388980, manufacturer reference DR500-20, is a professional copper tube compression lug designed for terminating 500 mm² copper conductors onto M20 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 DR500-20 is manufactured from electrolytic copper and designed for professional compression crimping. Its tubular construction provides the combination of electrical conductivity and mechanical strength required for substantial power connections, while the annealed copper supports controlled deformation of the barrel during installation with compatible crimping tooling.
With its 500 mm² conductor capacity and substantial M20 connection, the DR500-20 is particularly suited to high-current power distribution systems, switchgear, transformers and heavy industrial equipment. Its tin-plated copper construction helps protect against oxidation and supports dependable long-term electrical performance in demanding installations.

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 mechanical retention.
For large 500 mm² conductors, correct cable preparation, tooling and die selection are particularly important. The Cembre DR500-20 provides a purpose-designed termination for these substantial conductors, combining a large compression barrel with an M20 palm connection for demanding industrial and power distribution applications.
