Why Choose the Cembre 2190150 A5-M8 Copper Compression Ring Terminal?
The Cembre 2190150, also designated as the Cembre A5-M8, is a professional non-insulated copper compression ring terminal designed to terminate 25 mm² copper conductors onto M8 threaded studs. Part of the established Cembre A-M ring terminal series, it provides a secure, low-resistance connection for industrial control panels, switchgear, machinery and electrical power-distribution equipment.
Manufactured from annealed electrolytic copper with a purity above 99.95%, the Cembre A5-M8 combines excellent electrical conductivity with the ductility required for reliable compression crimping. Its electrolytic tin-plated finish helps protect the copper against oxidation and mechanical stress, supporting dependable long-term performance in demanding electrical installations.
The Cembre 2190150 features an 8.4 mm fixing hole for M8 studs, a chamfered easy-entry barrel and an integrated inspection hole. These features simplify conductor insertion and allow installers to verify that the cable is fully positioned before crimping, helping produce consistent and mechanically secure terminations.
