KLAUKE Tubular Cable Lug 25 mm² M6 Tin-Plated Copper 4R/6

The KLAUKE 4R/6 tubular cable lug is a high-quality connector designed for reliable and permanent electrical connections. Manufactured from electrolytic copper (E-Cu) with a tin-plated surface, it offers excellent corrosion resistance and conductivity. Suitable for stranded copper conductors (Classes 2, 5, 6), this lug is ideal for applications up to 1000 V and temperatures ranging from -50°C to +150°C.

Advantages

Tin-plated surface prevents oxidation and ensures long-lasting performance. The hexagonal crimping method provides a secure, gas-tight connection that exceeds DIN 46235 standards. The inspection hole-free design simplifies installation and reduces risk of damage.
