Why Choose the Cembre 2509742 Heavy Duty Two-Hole Ring Terminal?
The Cembre 2509742 is a premium heavy duty copper compression two-hole ring terminal (type 2A100-2M12) designed to provide secure, high-current electrical connections in demanding industrial, utility and medium-voltage applications. Manufactured from high-purity electrolytic copper and electrolytically tin-plated, it delivers outstanding conductivity together with long-term resistance to corrosion and environmental exposure.
As part of the proven Cembre 2A-M Series, this terminal features a double-length seamless barrel without an inspection hole, helping maximise both electrical and mechanical performance while preventing moisture ingress. The two-hole palm provides improved stability and resistance to rotation compared with conventional single-hole terminals, making it ideal for vibration-prone installations.
Designed for 500 mm² copper conductors with dual M12 fixing holes, the Cembre 2509742 is widely used in switchgear, substations, transformers, industrial control equipment and medium-voltage cable installations up to 35 kV.
