Why Choose the Cembre 2489570 BSCL350 Colour-Coded Butt Splice?
The Cembre 2489570, also identified as the BSCL350, is a heavy-duty colour-coded long-barrel butt splice connector designed for permanently joining 185 mm² copper conductors in industrial, commercial and utility electrical installations. As part of the proven Cembre BSCL series, this non-insulated compression connector delivers outstanding electrical conductivity, exceptional mechanical strength and dependable long-term performance.
Manufactured from annealed electrolytic copper with a purity greater than 99.95% and finished with electrolytic tin plating, the BSCL350 offers excellent corrosion resistance while maintaining a low-resistance electrical connection. Its extra-long barrel provides a large crimping area to produce secure, durable cable joints when installed using compatible Cembre compression tooling.
Designed for 185 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 red colour coding enables rapid identification of the correct connector size and matching compression die.
