2509952 Cembre 2A120-2M14/55 COPPER TERMINAL
Cembre 2509952 (2A120-2M14/55) heavy duty electrolytically tin-plated copper compression two-hole ring terminal for 630 mm² stranded copper conductors with dual M14 fixing holes at 55 mm centres.
Why Choose the Cembre 2509952 Heavy Duty Two-Hole Ring Terminal?
The Cembre 2509952 is a premium heavy duty copper compression two-hole ring terminal (type 2A120-2M14/55) engineered to deliver secure, low-resistance electrical connections for demanding industrial, utility and medium-voltage applications. Manufactured from greater than 99.9% pure electrolytic copper and electrolytically tin-plated, it provides exceptional electrical conductivity together with excellent corrosion resistance for long-term reliability.
Part of the proven Cembre 2A-2M Heavy Duty Series, this terminal features a double-length seamless barrel without an inspection hole to maximise both electrical and mechanical performance while preventing moisture ingress. The 55 mm two-hole fixing centres provide outstanding resistance to vibration and rotation, making the terminal ideal for high-current power distribution applications.
Designed for 630 mm² stranded copper conductors (or 500–630 mm² flexible copper conductors) with 2 × M14 fixing holes at 55 mm centres, the Cembre 2509952 is ideally suited to substations, transformers, switchgear, industrial control equipment and medium-voltage cable installations up to 35 kV.
