Why Choose the Cembre 2170810 A2-L4 90° Copper Ring Terminal?
The Cembre 2170810, also designated as the Cembre A2-L4, is a professional 90-degree non-insulated copper compression ring terminal designed to terminate 10 mm² copper conductors onto M4 threaded studs. As part of the established Cembre A-L angled ring terminal series, it provides a secure, low-resistance electrical connection where space restrictions or cable-routing requirements make a right-angle terminal preferable to a straight cable lug.
Manufactured from annealed electrolytic copper with a purity above 99.95%, the Cembre A2-L4 combines excellent electrical conductivity with the ductility required for dependable compression crimping. Its electrolytic tin-plated finish helps protect the copper against oxidation and corrosion, supporting reliable long-term performance in industrial control panels, machinery and electrical distribution equipment.
The Cembre 2170810 features a 90-degree connection angle, an M4 fixing hole with a 4.3 mm diameter and a chamfered easy-entry barrel for straightforward conductor insertion. An integrated inspection hole allows installers to confirm that the conductor is correctly positioned before crimping, helping produce consistent and mechanically secure cable terminations.

Reliable Angled Cable Termination for Compact Installations
A 90-degree compression ring terminal allows a conductor to approach the connection point at a right angle, reducing cable bending and simplifying routing inside confined electrical enclosures. This configuration is particularly useful where limited clearance prevents the use of a conventional straight ring terminal.
The Cembre A-L series creates a permanent electrical connection by compressing the annealed copper barrel 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 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.
