Why Choose the Cembre 2397688 CL350-12 Colour-Coded Copper Compression Lug?
The Cembre 2397688, manufacturer reference CL350-12, is a premium long-barrel colour-coded copper compression ring terminal designed for terminating large copper conductors in industrial power distribution, switchgear, renewable energy installations and heavy-duty electrical systems. Manufactured from annealed electrolytic copper with a purity greater than 99.9%, it provides exceptional electrical conductivity together with outstanding mechanical strength and long service life.
The CL Series features an extended barrel that increases conductor contact area while improving pull-out strength after crimping. The bevelled cable entry simplifies conductor insertion and helps prevent strand damage during installation. Unlike conventional inspection-hole terminals, the sealed barrel design helps minimise the ingress of moisture and contaminants, making the terminal particularly suitable for outdoor and demanding industrial environments.
Designed for 350 kcmil (approximately 185 mm²) copper conductors, the CL350-12 incorporates an M12 fixing hole (13.2 mm) together with red colour coding for rapid identification of the correct conductor size and compatible Cembre compression die.
