Cembre 2190030 A5-M4 straight electrolytically tin-plated copper compression terminal for 25 mm² copper conductors with an M4 fixing hole.
£0.88
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.
Compression terminals create permanent electrical and mechanical connections when installed using compatible professional crimping tools and correctly matched dies. The seamless copper barrel minimises electrical resistance while providing excellent resistance to vibration and conductor pull-out.
The straight palm configuration is ideal where conductors approach the fixing point directly, providing a compact, reliable termination solution for industrial machinery, electrical cabinets, switchgear and power distribution equipment.
