£15.30
The Cembre 2397420, manufacturer reference C300-34, is a premium colour-coded copper compression ring terminal designed to provide secure, low-resistance electrical terminations for large copper conductors. As part of the trusted Cembre C Series, it is widely specified for industrial switchgear, panel building, power distribution and infrastructure projects requiring reliable compression connections.
Manufactured from annealed electrolytic copper with an electrolytic tin-plated finish, the terminal offers outstanding electrical conductivity together with excellent resistance to corrosion and mechanical stress. The chamfered barrel entry and integrated inspection hole simplify installation and help ensure correct conductor insertion before crimping.
Designed for 300 kcmil (approximately 150 mm²) copper conductors, the C300-34 incorporates a 3/4-inch (M20) fixing hole, making it suitable for larger stud connections commonly found on busbars, transformers and heavy-duty electrical equipment.
Compression cable lugs provide permanent electrical and mechanical connections between copper conductors and equipment such as switchgear, transformers, generators and busbars. When installed using compatible Cembre crimping tools and dies, they produce secure, low-resistance terminations capable of handling demanding industrial loads.
The Cembre C Series combines precision manufacturing, premium materials and colour-coded identification to deliver reliable performance in industrial, commercial and utility electrical installations.
