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.

Key Advantages

  • Straight compression terminal for reliable electrical connections.
  • Suitable for 16 mm² copper conductors.
  • M6 fixing hole for secure bolted installation.
  • Manufactured from annealed electrolytic copper for excellent conductivity.
  • Electro-tinned finish provides enhanced corrosion resistance.
  • Inspection hole assists correct conductor insertion before crimping.

Key Features

  • Cembre A-B Series straight compression terminal.
  • Manufacturer Part Number: 2181500.
  • Alternative SKU: A3B-M6.
  • Nominal conductor size: 16 mm².
  • M6 ring terminal.
  • Electrolytic copper tube construction.
  • Electrolytically tin-plated finish.
  • Inspection hole and chamfered barrel.

Reliable Copper Cable Termination for Industrial Installations

Compression terminals create a permanent electrical and mechanical connection when installed using the correct professional crimping tool and die set. The seamless copper barrel provides low contact resistance while maintaining excellent resistance to vibration and conductor pull-out.

The straight palm configuration is ideal for applications where cables approach terminals directly, providing a compact and reliable solution for electrical panels, switchgear and industrial machinery.

Typical Applications

  • Industrial control panels.
  • Power distribution equipment.
  • Switchgear assemblies.
  • Motor control centres.
  • Machine building and OEM equipment.
