Cembre 2489570 BSCL350 colour-coded long-barrel non-insulated butt splice connector for joining 185 mm² copper conductors using compression crimping.
£19.60
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.
Compression butt splice connectors create permanent, low-resistance electrical joints while maintaining exceptional mechanical integrity. The Cembre BSCL range is engineered for demanding industrial environments where reliability, conductivity and long service life are essential.
The BSCL350 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 service life.
