KLAU 7R12 terminal de cobre 70 mm² M12, estanhado eletroliticamente, DIN 46235

In high-current electrical installations, unreliable connections can lead to overheating, voltage drops, and even equipment failure. The KLAU 7R12 copper crimp cable lug eliminates these risks by providing a permanent, low-resistance joint between a 70 mm² copper conductor and an M12 stud or bolt. Manufactured from electrolytic copper and electro-tinned for corrosion resistance, this lug is engineered for demanding industrial and power distribution environments.

Who is it for

Electricians, panel builders, and maintenance technicians who need dependable terminations for large cross-section cables. It suits applications in switchgear, motor control centers, grounding systems, and renewable energy installations where vibration, thermal cycling, and moisture are present.

Tips

For optimal performance, use a hexagonal crimping die matched to the lug size and ensure the conductor is fully inserted into the barrel before crimping. Apply heat-shrink tubing over the barrel after crimping for additional insulation and environmental sealing if required.
