Cembre 2506400 (2A30-2M12) heavy-duty electrolytic copper compression ring terminal for 150 mm² conductors with two M12 fixing holes and electro-tinned finish.
£22.55
The Cembre 2506400, also identified as 2A30-2M12, is a premium heavy-duty copper compression ring terminal designed for terminating large copper conductors in demanding industrial power distribution systems. Manufactured from greater than 99.9% purity electrolytic copper with an electrolytic tin-plated finish, it provides excellent conductivity, outstanding corrosion resistance and long-term mechanical reliability.
Part of Cembre's renowned 2A-2M heavy-duty terminal series, this terminal incorporates a two-hole fixing palm and a long compression barrel without an inspection hole. This design improves mechanical stability, resists electrodynamic forces and helps prevent moisture ingress, making it suitable for both indoor and outdoor industrial installations.
Designed for 150 mm² copper conductors with dual M12 fixing holes, the 2A30-2M12 is ideal for switchgear, transformers, substations, grounding systems and medium-voltage applications up to 35 kV when installed using compatible Cembre compression tooling.
Heavy-duty copper compression terminals provide low-resistance electrical connections while maintaining excellent mechanical integrity under high-current operating conditions. Their robust construction makes them ideal for industrial power distribution systems where dependable long-term performance is essential.
The Cembre 2A-2M series combines annealed electrolytic copper, electrolytic tin plating and a double-hole fixing arrangement to provide excellent crimp performance, superior resistance to vibration and long service life in demanding industrial environments.
