Why Choose the Cembre 2181500 A3B-M6 Copper Terminal?
The Cembre 2181500, also identified as the Cembre A3B-M6, is a high-quality straight copper compression terminal designed to provide secure, low-resistance electrical connections for stranded and flexible copper conductors. Manufactured for demanding industrial environments, it delivers dependable performance in electrical panels, machinery and power distribution systems.
Manufactured from high-conductivity electrolytic copper, the terminal is annealed to maximise ductility during crimping and electrolytically tin-plated to improve corrosion resistance. This combination ensures excellent electrical conductivity, strong mechanical performance and long service life even in applications subject to vibration.
The Cembre A3B-M6 is designed for 16 mm² copper conductors and features an M6 fixing hole, making it ideal for industrial control panels, switchgear, OEM equipment, motor control centres and commercial electrical installations requiring professional compression terminations.
