Why Choose the Cembre 2190120 A5-M6/11 Narrow-Palm Copper Ring Terminal?
The Cembre 2190120, also designated as the Cembre A5-M6/11, is a premium non-insulated copper compression ring terminal designed for terminating 25 mm² copper conductors onto M6 threaded studs. As part of Cembre's specialist A-M contained-palm series, it is engineered for low-voltage circuit breakers, switchgear and electrical equipment where a reduced palm width is required without compromising electrical performance.
Manufactured from annealed electrolytic copper with a purity exceeding 99.95%, the A5-M6/11 delivers excellent electrical conductivity and outstanding crimping performance. An electrolytic tin-plated finish provides long-term protection against oxidation and corrosion, making it suitable for demanding industrial and commercial installations.
Its compact 11 mm palm width allows installation into confined terminal spaces, while the internally chamfered barrel and inspection hole simplify conductor insertion and help ensure consistent, reliable compression crimps.

Contained-palm compression terminals are specifically designed for low-voltage circuit breakers and compact equipment where standard-width cable lugs cannot be accommodated. The reduced palm width allows installation into narrow terminal spaces while maintaining excellent electrical conductivity and mechanical strength.
When installed using the correct Cembre compression tooling and dies, the A5-M6/11 provides a permanent low-resistance electrical connection capable of withstanding vibration, thermal cycling and demanding industrial operating conditions.
Typical Applications
- Low-voltage circuit breakers.
- Industrial control panels.
- Switchgear assemblies.
- Power distribution equipment.
- OEM machinery.
- Industrial electrical maintenance.
