Why Choose the Cembre 2170850 A2-L8 90° Copper Ring Terminal?
The Cembre 2170850, also designated as the Cembre A2-L8, is a professional 90-degree non-insulated copper compression ring terminal designed to terminate 10 mm² copper conductors onto M8 threaded studs. As part of the established Cembre A-L angled ring terminal series, it provides a secure, low-resistance electrical connection where restricted clearance or cable-routing requirements make a right-angle terminal preferable to a conventional straight cable lug.
Manufactured from electrolytic copper tube with a purity greater than 99.9%, the Cembre A2-L8 delivers excellent electrical conductivity and the mechanical strength required to resist vibration and conductor pull-out. The terminal is annealed to provide optimum ductility during compression, while its electrolytic tin-plated finish improves resistance to oxidation, corrosion and mechanical stress.
The Cembre 2170850 features a 90-degree angled palm, an M8 fixing hole with an 8.4 mm diameter and a chamfered barrel entry for straightforward conductor insertion. An integrated inspection hole allows installers to verify that the conductor is fully inserted before crimping, helping produce consistent and mechanically reliable cable terminations.

Reliable Angled Cable Termination for Compact Installations
A 90-degree compression ring terminal allows the conductor to approach the connection point from the side, reducing cable bending and simplifying routing inside compact electrical enclosures. This configuration is particularly useful where limited clearance prevents the installation of a conventional straight ring terminal.
The Cembre A-L series creates a permanent electrical connection by compressing the annealed copper barrel securely around the conductor strands. When installed using a compatible professional crimping tool and the correct die, the terminal provides excellent electrical continuity, strong pull-out resistance and dependable performance under vibration and thermal cycling.
