Why Choose the Cembre A60-4ESI Four-Hole Transformer Cable Lug?
The Cembre 2350850 A60-4ESI is a heavy-duty four-hole copper compression transformer lug designed for secure termination of large copper conductors onto standard transformer fixing arrangements. Its four-bolt palm provides excellent mechanical stability for demanding low-voltage and medium-voltage power-distribution installations.
Manufactured from electrolytic copper tube with a purity greater than 99.9%, the terminal is annealed to provide the ductility required during compression crimping. Its electrolytically tin-plated finish helps protect the copper against oxidation and corrosion, supporting dependable long-term electrical performance.
The A60-4ESI accommodates 300 mm² stranded copper conductors and selected 240 mm² flexible copper conductors. Four fixing holes arranged on standard 25 mm by 35 mm centres ensure compatibility with commonly used ESI transformer terminals.
Key Advantages
- Four-hole ESI fixing arrangement suits common transformer terminals.

Reliable Four-Bolt Transformer Connections
The four-hole palm distributes fixing pressure across a wide contact area, helping prevent rotation and movement under vibration, thermal cycling and fault-current forces. Its ESI-compatible fixing pattern allows the terminal to be installed directly onto many standard transformer connection points.
When installed using compatible Cembre crimping equipment and the correct die set, the A60-4ESI forms a durable, low-resistance connection with strong conductor retention. The chamfered barrel entry assists conductor insertion, while the inspection hole allows the installer to confirm correct positioning before crimping.
Typical Applications
- Low-voltage transformer connections.
- Medium-voltage transformer cable terminations.
- Transformer secondary terminals.
- Electrical substations.
- Utility power-distribution networks.
- Industrial switchgear and switchboards.
- High-current busbar and power-equipment connections.
