Cembre 2489515 BSCL6 colour-coded long-barrel non-insulated butt splice connector for joining 16 mm² copper conductors using compression crimping.
£1.94
The Cembre 2489515, also identified as the BSCL6, is a premium colour-coded long-barrel butt splice connector designed for permanently joining copper conductors in industrial and commercial electrical installations. As part of the proven Cembre BSCL series, it delivers a reliable, low-resistance compression joint with excellent mechanical strength.
Manufactured from annealed electrolytic copper with a purity greater than 99.9% and finished with electrolytic tin plating, the BSCL6 offers outstanding electrical conductivity together with long-term corrosion resistance. The long-barrel design provides an extended crimping area, helping achieve consistent and secure compression when used with compatible Cembre tooling.
Designed for 16 mm² copper conductors, the connector features tapered conductor entries at both ends and an integrated central stop to ensure correct cable positioning before crimping. Its blue colour coding allows quick identification of the correct connector size and matching crimp die.
Compression butt splice connectors provide a permanent electrical connection between conductors while maintaining excellent current carrying capability and mechanical integrity. The Cembre BSCL series has been developed for demanding industrial applications where long-term connection reliability is essential.
The BSCL6 features a long compression barrel that distributes crimping forces over a larger area, producing a secure connection with low electrical resistance. The annealed copper construction allows controlled deformation during compression, while the tin-plated finish helps protect against oxidation and corrosion.

The BSCL6 is designed to permanently join two compatible 16 mm² copper conductors using compression crimping.
This connector is designed for 16 mm² copper conductors, approximately equivalent to 6 AWG.
No. The Cembre BSCL6 is a non-insulated butt splice and should be insulated after installation where required.
The electrolytic tin plating improves corrosion resistance while maintaining excellent electrical conductivity over the life of the installation.
Yes. An integrated central stop ensures both conductors are inserted to the correct depth before compression.
Cembre BSCL compression connectors are widely specified by panel builders, industrial electricians, utilities and OEM manufacturers for dependable copper cable jointing in demanding electrical installations.
