Why Choose the Cembre 2180310 A3-M12 Copper Compression Ring Terminal?
The Cembre 2180310, also designated as the Cembre A3-M12, is a professional non-insulated copper compression ring terminal designed to terminate 16 mm² copper conductors onto M12 threaded studs. 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 high-purity electrolytic copper tube, the Cembre A3-M12 combines excellent electrical conductivity with the mechanical strength required to resist vibration and conductor pull-out. The terminal is annealed to provide the ductility needed during compression crimping and is electrolytically tin plated to improve resistance to oxidation, corrosion and mechanical stress.
The Cembre 2180310 features a 13.2 mm fixing hole for M12 studs, a chamfered barrel entry and an integrated inspection hole. These features simplify conductor insertion and allow installers to confirm that the cable is correctly positioned before crimping, helping create consistent and mechanically reliable terminations.
