Why Choose the Cembre 2190290 A5-M16 Copper Compression Ring Terminal?
The Cembre 2190290, also designated as the Cembre A5-M16, is a professional non-insulated copper compression ring terminal designed to terminate 25 mm² copper conductors onto M16 threaded studs. Part of the proven Cembre A-M copper tube terminal series, it provides a secure, low-resistance electrical connection for industrial switchgear, power distribution equipment, control panels and heavy-duty machinery.
Manufactured from annealed electrolytic copper tube with a purity greater than 99.9%, the A5-M16 delivers outstanding electrical conductivity together with excellent mechanical strength. The electrolytic tin-plated finish protects against oxidation and corrosion, while the annealed construction ensures optimum ductility for dependable compression crimping.
The Cembre 2190290 features a 17 mm fixing hole for M16 studs, a chamfered easy-entry barrel and an integrated inspection hole. These design features simplify conductor insertion and allow installers to verify correct cable positioning before crimping, helping produce reliable, long-lasting electrical terminations.
