Why Choose the Cembre 2170820 A2-L5 90° Copper Ring Terminal?
The Cembre 2170820, also designated as the Cembre A2-L5, is a professional 90-degree non-insulated copper compression ring terminal designed to terminate 10 mm² copper conductors onto M5 threaded studs. As part of the established Cembre A-L angled ring terminal series, it provides a secure, low-resistance electrical connection where restricted space or cable-routing requirements make a right-angle terminal preferable to a conventional straight cable lug.
Manufactured from annealed electrolytic copper with a purity greater than 99.9%, the Cembre A2-L5 combines excellent electrical conductivity with the ductility required for reliable compression crimping. Its electrolytic tin-plated finish helps protect the copper against oxidation and corrosion, supporting dependable long-term performance in industrial control panels, switchgear, machinery and electrical distribution systems.
The Cembre 2170820 features a 90-degree angled palm, an M5 fixing hole with a 5.3 mm diameter and an easy-entry barrel for straightforward conductor insertion. An integrated inspection hole allows installers to verify that the conductor is correctly positioned before crimping, helping produce consistent and mechanically secure cable terminations.

- Suitable for hexagonal and indent compression crimping.
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.
Typical Applications
- Compact industrial control panels and electrical cabinets.
- Switchgear and power distribution equipment.
- Motor control centres and machinery connections.
- OEM automation equipment and cable assemblies.
- Terminal blocks and equipment connections with restricted clearance.
- Industrial maintenance and electrical installation projects.
