Why Choose the Cembre CA50S-2M12 Copper Compression Cable Lug?
The Cembre CA50S-2M12 (2531190) is a premium two-hole copper compression cable lug engineered for secure, low-resistance electrical terminations in medium-voltage power distribution, substations, switchgear and industrial installations. As part of the robust Cembre CA-2M series, it delivers outstanding electrical conductivity, superior mechanical stability and long-term reliability for demanding electrical applications.
Manufactured from high-purity annealed electrolytic copper (>99.9%) with an electrolytic tin-plated finish, the CA50S-2M12 provides exceptional corrosion resistance while maintaining excellent conductivity. Its extended barrel improves both electrical and mechanical performance, while the closed barrel design without an inspection hole helps prevent moisture ingress, making it suitable for outdoor installations and medium-voltage systems up to 35 kV.
Designed for 50 mm² sector copper conductors, the terminal incorporates two M12 fixing holes with 44.5 mm centre spacing, providing increased resistance to vibration and electrodynamic forces in switchgear, renewable energy installations and industrial power distribution systems.
