Why Choose the Cembre 2180350 A3-M14 Copper Compression Ring Terminal?
The Cembre 2180350, also designated as the Cembre A3-M14, is a professional non-insulated copper compression ring terminal designed to terminate 16 mm² copper conductors onto M14 threaded studs. Part of the established Cembre A-M terminal series, it provides a secure, low-resistance cable connection for switchgear, control panels, machinery and industrial power-distribution equipment.
The terminal is manufactured from electrolytic copper tube with a purity greater than 99.9%, delivering excellent electrical conductivity and the mechanical strength required to resist vibration and conductor pull-out. Its annealed construction provides the ductility needed during compression crimping, while the electrolytic tin-plated finish helps protect the copper against oxidation and corrosion.
The Cembre 2180350 features a ring palm for M14 studs, a funnel-shaped chamfered barrel entry and an integrated inspection hole. These design features simplify conductor insertion and allow the installer to confirm that the cable is fully positioned before crimping, helping produce consistent and mechanically reliable terminations.
Key Advantages
- Designed for dependable termination of 16 mm² copper conductors.
- M14 stud compatibility for secure bolted connections.
- High-purity electrolytic copper provides excellent conductivity.
- Annealed construction supports reliable compression and palm positioning.
- Electrolytic tin plating improves oxidation and corrosion resistance.
- Inspection hole enables verification of correct conductor insertion.
Key Features
- Cembre A-M copper compression ring terminal series.
- Manufacturer part number: 2180350.
- Terminal designation: A3-M14.
- 16 mm² / approximately 6 AWG conductor compatibility.
- M14 fixing-hole configuration.
- Funnel-shaped, internally chamfered barrel entry.

- Suitable for professional hexagonal and indent crimping.
Copper compression ring terminals create a permanent electrical joint by compressing the terminal barrel tightly around the conductor strands. A correctly installed crimp provides excellent electrical continuity, strong pull-out resistance and reliable operation under vibration, mechanical stress and temperature changes.
The M14 ring configuration makes the Cembre A3-M14 suitable for equipment with larger threaded connection points, while its 16 mm² barrel maintains compatibility with commonly used industrial copper conductors. The extended palm and straight connection angle support secure mounting to busbars, terminals and equipment connection points.
Typical Applications
- Industrial control panels and electrical cabinets.
- Switchgear and power-distribution assemblies.
- Busbar and equipment-terminal connections.
- Motor control centres and industrial machinery.
- OEM automation equipment and cable assemblies.
- Electrical maintenance and installation projects.
