Cembre 2489545 BSCL2/0 colour-coded long-barrel non-insulated butt splice connector for joining 70 mm² copper conductors using compression crimping.
£5.44
The Cembre 2489545, also identified as the BSCL2/0, is a premium colour-coded long-barrel butt splice connector designed for permanently joining 70 mm² copper conductors in industrial, commercial and utility electrical installations. As part of the trusted Cembre BSCL series, this non-insulated compression connector delivers excellent electrical conductivity, high mechanical strength and long-term reliability.
Manufactured from annealed electrolytic copper with a purity greater than 99.95% and finished with electrolytic tin plating, the BSCL2/0 provides exceptional corrosion resistance while maintaining a low-resistance electrical connection. Its extended long-barrel design increases the crimping area, producing secure and durable cable joints when installed using compatible Cembre compression tooling.
Designed for 70 mm² copper conductors, the connector incorporates tapered conductor entries at both ends together with an integrated central conductor stop for accurate conductor positioning before crimping. The black colour coding enables rapid identification of the correct connector size and corresponding compression die.
Compression butt splice connectors create permanent, low-resistance electrical joints while maintaining outstanding mechanical integrity. The Cembre BSCL range is engineered for demanding industrial environments where reliability, conductivity and long service life are essential.
The BSCL2/0 combines an extended long-barrel design with annealed electrolytic copper construction to maximise conductor contact during crimping. Its electrolytic tin-plated finish protects the connection against oxidation and corrosion, ensuring dependable performance throughout the installation's lifetime.
