Cembre 2170850 A2-L8 non-insulated 90-degree tin-plated copper compression ring terminal for terminating 10 mm² copper conductors onto M8 studs.
£1.57
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.
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.

The Cembre 2170850 is used to terminate 10 mm² copper conductors onto M8 threaded studs where a compact 90-degree cable connection is required.
The terminal is designed for 10 mm² flexible and low-stranded copper conductors, equivalent to approximately 8 AWG.
The Cembre 2170850 is designed for M8 studs and bolts and features a nominal fixing-hole diameter of 8.4 mm.
The 90-degree angled palm allows the conductor to approach the fixing point from the side, making the terminal suitable for confined spaces and installations where straight cable routing is impractical.
The conductor should be stripped to the recommended length, inserted fully into the barrel and crimped using a compatible professional compression tool with the correct die for a 10 mm² conductor.
Cembre A-L angled copper compression terminals are widely used by electrical contractors, panel builders and OEM manufacturers to create secure, space-efficient and mechanically reliable cable connections.
