Why Choose the Cembre 2489510 BSCL8 Colour-Coded Butt Splice?
The Cembre 2489510, also identified as the BSCL8, is a high-quality colour-coded long-barrel butt splice connector designed for joining copper conductors in demanding electrical installations. Manufactured as part of the dependable Cembre BSCL series, this non-insulated compression connector provides a secure, low-resistance and mechanically robust cable joint.
The connector is manufactured from annealed electrolytic copper with a purity greater than 99.9% and is electrolytically tin plated to improve corrosion resistance and long-term electrical performance. Its long-barrel construction provides an extended crimping area, helping create a strong and reliable connection when installed using a compatible Cembre crimping tool and die.
Designed for 10 mm² copper conductors, the Cembre BSCL8 incorporates internally tapered entrances at both ends to simplify conductor insertion. A central conductor stop assists with accurate cable positioning before compression, while the red colour coding supports rapid identification of the correct connector and crimping system.

Reliable Compression Jointing for Copper Cables
Compression butt splices are used to create permanent electrical connections between two conductors of the same or compatible cross-section. When correctly compressed, the connector forms a strong mechanical bond while maintaining a low-resistance electrical path through the joint.
The Cembre BSCL8 long-barrel design provides a substantial contact and compression area around each conductor. The annealed copper body deforms consistently during crimping, while the tin-plated surface helps protect the connection against oxidation and environmental exposure.
For dependable performance, conductors should be correctly stripped, fully inserted against the central stop and compressed using the approved Cembre tool and die combination. The completed connection should then be insulated and protected according to the voltage rating and environmental requirements of the installation.

Frequently Asked Questions
What is the Cembre 2489510 used for?
The Cembre 2489510 BSCL8 is used to create a permanent straight-through compression joint between two compatible copper conductors.
What cable size is suitable for the Cembre BSCL8?
The BSCL8 is designed for 10 mm² copper conductors, approximately equivalent to 8 AWG.
Is the Cembre 2489510 insulated?
No. It is a non-insulated butt splice, so the completed connection must be insulated using a suitable heat-shrink sleeve, jointing system or other approved insulation method.
Why does the connector have a long barrel?
The long barrel provides an extended compression and contact area, helping produce a strong mechanical joint and a reliable low-resistance electrical connection.
What material is the BSCL8 manufactured from?
It is manufactured from annealed electrolytic copper with a purity greater than 99.9% and features an electrolytically tin-plated surface.
What does the red colour code indicate?
The red colour code assists installers in identifying the connector size and selecting the appropriate compatible crimping die.
Which tool should be used to install the Cembre 2489510?
The connector must be compressed using a compatible Cembre mechanical or hydraulic crimping tool fitted with the correct die for the BSCL8 connector and conductor size.
