Cembre 2170860 A2-L10 non-insulated 90-degree tin-plated copper compression ring terminal for terminating 10 mm² copper conductors onto M10 studs.
£1.89
The Cembre 2170860, also designated as the Cembre A2-L10, is a professional 90-degree non-insulated copper compression ring terminal designed to terminate 10 mm² copper conductors onto M10 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 annealed electrolytic copper with a purity above 99.95%, the Cembre A2-L10 combines excellent electrical conductivity with the ductility required for dependable compression crimping. Its electrolytic tin-plated surface helps protect the copper against oxidation while improving resistance to mechanical stress, supporting reliable long-term performance in demanding industrial environments.
The Cembre 2170860 features a 90-degree angled palm, an M10 fixing hole with a 10.5 mm diameter and a chamfered easy-entry barrel for straightforward conductor insertion. An integrated inspection hole allows installers to confirm that the conductor is fully inserted before crimping, helping produce consistent and mechanically secure 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 use of a conventional straight ring terminal or where improved cable management is required.
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, high pull-out resistance and dependable performance under vibration, mechanical stress and thermal cycling.

The Cembre 2170860 is used to terminate 10 mm² copper conductors onto M10 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 2170860 is designed for M10 studs and bolts and features a nominal fixing-hole diameter of 10.5 mm.
The 90-degree angled palm allows the conductor to approach the connection 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 approximately 9 mm, 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.
