Cembre 2506410 (2A30-2M14) heavy-duty electrolytic copper compression ring terminal for 150 mm² conductors with two M14 fixing holes and electro-tinned finish.
£22.55
The Cembre 2506410, also identified as 2A30-2M14, 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 exceptional electrical conductivity, corrosion resistance and long-term reliability in demanding industrial environments.
Part of Cembre's proven 2A-2M heavy-duty terminal series, this terminal features a two-hole fixing palm that delivers superior mechanical stability under vibration and electrodynamic stress. The long compression barrel incorporates a chamfered entry for easier conductor insertion and omits the inspection hole to help minimise moisture ingress.
Designed for 150 mm² copper conductors with dual M14 fixing holes, the 2A30-2M14 is ideal for switchgear, transformers, substations, grounding systems and medium-voltage installations 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.

The Cembre 2506410 is a heavy-duty copper compression ring terminal designed for terminating 150 mm² copper conductors in industrial power distribution and grounding systems.
The alternative product reference is 2A30-2M14.
The two-hole palm provides increased mechanical stability and improved resistance to vibration and electrodynamic forces compared with single-hole terminals.
The conductor is inserted into the long barrel and permanently secured using the appropriate Cembre compression crimping tool and matching dies.
Typical installations include switchgear, substations, transformers, grounding systems and industrial power distribution equipment.
Cembre heavy-duty copper compression terminals are trusted by electrical contractors, panel builders and power engineers for delivering reliable, low-resistance conductor terminations in demanding industrial and utility applications.
