Cembre 2180350 A3-M14 non-insulated tin-plated copper compression ring terminal for terminating 16 mm² copper conductors onto M14 threaded studs.
£9.56
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.
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.

The Cembre 2180350 is used to terminate 16 mm² copper conductors onto M14 threaded studs in industrial electrical equipment, switchgear and power-distribution systems.
The terminal is designed for 16 mm² flexible and low-stranded copper conductors, equivalent to approximately 6 AWG.
The Cembre 2180350 is manufactured for use with M14 threaded studs and bolts.
Yes. The barrel includes an inspection hole that allows the installer to confirm that the conductor has been inserted correctly before crimping.
The conductor should be stripped to the appropriate length, inserted fully into the chamfered barrel and compressed using a compatible professional crimping tool and the correct die for a 16 mm² conductor.
Cembre A-M copper compression terminals are widely used by electrical contractors, panel builders, OEM manufacturers and maintenance engineers to create secure, durable and electrically efficient cable connections.
