Why Choose the Cembre 2489520 BSCL4 Colour-Coded Butt Splice?
The Cembre 2489520, also identified as the BSCL4, is a premium colour-coded long-barrel butt splice connector designed for permanently joining copper conductors in industrial, commercial and utility electrical installations. Part of the trusted Cembre BSCL series, this non-insulated compression connector delivers outstanding electrical conductivity together with exceptional mechanical strength for demanding applications.
Manufactured from annealed electrolytic copper with a purity greater than 99.9% and finished with electrolytic tin plating, the BSCL4 provides excellent corrosion resistance and long-term reliability. Its long-barrel construction increases the compression area, producing secure, low-resistance cable joints when installed using compatible Cembre compression tooling.
Designed for 25 mm² copper conductors, the connector features tapered conductor entries at both ends together with an integrated central conductor stop to ensure accurate conductor positioning before crimping. The grey colour coding enables quick identification of the correct connector and die combination during installation.
