Why Choose the Cembre 2480020 Copper Through Connector?
The Cembre 2480020 (L03-M) is a high-quality copper compression through connector (butt splice) designed for permanently joining low-voltage copper conductors. As part of the proven Cembre L-M Series, it provides secure, low-resistance electrical splices for industrial, commercial and utility electrical installations.
Manufactured from more than 99.9% pure electrolytic copper and finished with electrolytic tin plating, the connector delivers outstanding electrical conductivity together with excellent resistance to corrosion. The annealed construction ensures optimum ductility for reliable compression while increasing resistance to mechanical stress.
The L03-M features chamfered barrel entries to simplify conductor insertion together with an internal central stop that ensures both conductors are positioned correctly before crimping. It is ideal for permanently joining 0.25–1.5 mm² copper conductors using compatible Cembre crimping tools and dies.
