Why Choose the Cembre 2200270 A7-M14 Copper Compression Ring Terminal?
The Cembre 2200270, also designated as the Cembre A7-M14, is a professional non-insulated copper compression ring terminal designed to terminate 35 mm² copper conductors onto M14 threaded studs. Part of the established Cembre A-M cable lug series, it provides a secure, low-resistance connection for industrial switchgear, control panels, machinery and electrical power-distribution equipment.
Manufactured from high-purity electrolytic copper tube, the Cembre A7-M14 combines excellent electrical conductivity with the mechanical strength required to resist vibration and conductor pull-out. The copper is annealed to provide optimum ductility during compression crimping, while the electrolytic tin-plated finish helps protect the terminal against oxidation and corrosion.
The Cembre 2200270 combines a barrel sized for 35 mm² stranded copper cable with a substantial M14 ring palm. Its internally chamfered barrel entry helps guide the conductor strands into position, while the inspection hole allows installers to verify correct conductor insertion before completing the crimp.

Copper compression terminals create a permanent electrical joint by mechanically compressing the terminal barrel around the conductor strands. When installed with the correct tool and die, the resulting connection provides excellent electrical continuity, strong pull-out resistance and dependable performance under vibration, mechanical stress and thermal cycling.
The M14 ring configuration makes the Cembre A7-M14 suitable for equipment with substantial threaded connection points, while its 35 mm² barrel supports industrial power and distribution conductors. For optimum performance, the terminal should be fitted using compatible Cembre compression tooling selected for the conductor size and terminal series.
