Why Choose the Cembre 2170310 A2-M12 Copper Ring Terminal?
The Cembre 2170310, also designated as the Cembre A2-M12, is a high-quality non-insulated copper compression ring terminal designed to terminate 10 mm² copper conductors onto M12 threaded studs. As part of the established Cembre A-M ring terminal series, it provides a secure, low-resistance electrical connection for industrial control panels, switchgear, machinery and power distribution equipment.
Manufactured from annealed electrolytic copper with a purity above 99.95%, this terminal offers excellent electrical conductivity, mechanical strength and ductility during crimping. Its electrolytic tin-plated finish helps protect the copper against oxidation and corrosion, supporting dependable long-term performance in demanding industrial environments.
The Cembre 2170310 features a 13.2 mm fixing hole, a 19.1 mm palm width and an easy-insertion barrel that simplifies conductor positioning. An integrated inspection hole allows installers to confirm that the conductor has been fully inserted before crimping, helping produce consistent and mechanically reliable cable terminations.

Reliable Copper Cable Termination for Industrial Installations
Compression ring terminals create permanent electrical connections by mechanically compressing the terminal barrel around the conductor strands. A correctly completed crimp provides excellent electrical continuity, high pull-out resistance and dependable performance in installations exposed to vibration, thermal cycling and continuous electrical loads.
The Cembre A-M series is designed for electrical contractors, panel builders and industrial engineers who require repeatable termination quality. Its annealed copper construction, easy-insertion barrel and inspection hole simplify installation while helping ensure secure and consistent connections when used with a compatible professional crimping tool.
Typical Applications
- Industrial control panels and electrical cabinets.
- Switchgear and power distribution assemblies.
- Motor control centres and motor connections.
- OEM machinery and factory automation equipment.
- Busbar and terminal-block connections.
- Industrial maintenance and electrical installation projects.
