Klauke koperen buiskabelschoen 6R12 50mm² M12

Secure, low-resistance electrical connections demand a terminal that can handle high current without overheating or loosening. The Klauke Copper Tubular Cable Lug 6R12 is engineered for exactly that: a robust, pure copper crimp lug for 50 mm² conductors with an M12 bolt hole, ensuring a durable and reliable link in power distribution, switchgear, and industrial installations.

Who is it for

This cable lug is built for professional electricians, panel builders, and maintenance technicians who need dependable terminations for stranded copper cables up to 50 mm². It suits applications where vibration, thermal cycling, or high current demand a solid mechanical and electrical bond—think motor connections, earthing systems, and busbar terminations.

Main features

• Made from high-purity electrolytic copper (>99.9% Cu) for excellent conductivity and corrosion resistance.
• Standard barrel design with inspection hole to verify full conductor insertion before crimping.
• One M12 mounting hole (12.5 mm diameter) for secure bolted connections.
• Compatible with stranded copper conductors Class 2, 5, and 6 (fine, extra-fine, and rigid).
• Bare copper surface—no plating—ideal for direct crimping and optional tinning on site.
• Wide operating temperature range: -55°C to +150°C, suitable for harsh environments.
• RoHS compliant and manufactured to Klauke's stringent quality standards.
