Why Choose the Cembre 2190030 A5-M4 Copper Compression Terminal?
The Cembre 2190030, also identified as the Cembre A5-M4, is a premium straight copper compression terminal designed to provide secure, low-resistance terminations for stranded and flexible copper conductors. As part of the trusted Cembre A-M Series, it is engineered for dependable performance in industrial control panels, switchgear, machinery and electrical distribution systems.
Manufactured from high-purity electrolytic copper tube, the terminal is annealed to improve ductility during crimping and electrolytically tin plated to provide long-term protection against corrosion. A chamfered barrel and inspection hole simplify conductor insertion and help ensure consistent, professional-quality crimps.
Designed for 25 mm² copper conductors and incorporating an M4 fixing hole, the Cembre A5-M4 is ideal for OEM machinery, motor control centres, switchboards, electrical control panels and commercial electrical installations requiring reliable compression terminations.
