Why Choose the Cembre 2170820 A2-L5 90° Copper Ring Terminal?

The Cembre 2170820, also designated as the Cembre A2-L5, is a professional 90-degree non-insulated copper compression ring terminal designed to terminate 10 mm² copper conductors onto M5 threaded studs. As part of the established Cembre A-L angled ring terminal series, it provides a secure, low-resistance electrical connection where restricted space or cable-routing requirements make a right-angle terminal preferable to a conventional straight cable lug.

Manufactured from annealed electrolytic copper with a purity greater than 99.9%, the Cembre A2-L5 combines excellent electrical conductivity with the ductility required for reliable compression crimping. Its electrolytic tin-plated finish helps protect the copper against oxidation and corrosion, supporting dependable long-term performance in industrial control panels, switchgear, machinery and electrical distribution systems.

The Cembre 2170820 features a 90-degree angled palm, an M5 fixing hole with a 5.3 mm diameter and an easy-entry barrel for straightforward conductor insertion. An integrated inspection hole allows installers to verify that the conductor is correctly positioned before crimping, helping produce consistent and mechanically secure cable terminations.

Key Advantages

  • Compact 90-degree copper compression ring terminal for confined installation spaces.
  • 10 mm² conductor capacity suitable for industrial electrical applications.
  • M5 stud compatibility for secure bolted connections.
  • High-purity annealed copper provides excellent conductivity and crimping performance.
  • Electrolytic tin plating improves resistance to oxidation and corrosion.
  • Inspection hole enables confirmation of correct conductor insertion.

Key Features

  • Cembre A-L 90-degree ring terminal series.
  • Manufacturer part number: 2170820.
  • Terminal designation: A2-L5.
  • 10 mm² / 8 AWG conductor compatibility.
  • M5 fixing hole with a nominal 5.3 mm diameter.
  • 90-degree angled palm for space-efficient cable routing.
  • Chamfered easy-insertion barrel with an integrated inspection hole.
  • Suitable for hexagonal and indent compression crimping.

Reliable Angled Cable Termination for Compact Installations

A 90-degree compression ring terminal allows the conductor to approach the connection point from the side, reducing cable bending and simplifying routing inside compact electrical enclosures. This configuration is particularly useful where limited clearance prevents the installation of a conventional straight ring terminal.

The Cembre A-L series creates a permanent electrical connection by compressing the annealed copper barrel securely around the conductor strands. When installed using a compatible professional crimping tool and the correct die, the terminal provides excellent electrical continuity, strong pull-out resistance and dependable performance under vibration and thermal cycling.

Typical Applications

  • Compact industrial control panels and electrical cabinets.
  • Switchgear and power distribution equipment.
  • Motor control centres and machinery connections.
  • OEM automation equipment and cable assemblies.
  • Terminal blocks and equipment connections with restricted clearance.
  • Industrial maintenance and electrical installation projects.

Frequently Asked Questions

What is the Cembre 2170820 used for?

The Cembre 2170820 is used to terminate 10 mm² copper conductors onto M5 threaded studs where a compact 90-degree cable connection is required.

What conductor size does the Cembre A2-L5 support?

The terminal is designed for 10 mm² flexible copper conductors, equivalent to approximately 8 AWG.

What stud size is compatible with this terminal?

The Cembre 2170820 is designed for M5 studs and bolts and features a nominal fixing-hole diameter of 5.3 mm.

Why does the Cembre 2170820 have a 90-degree bend?

The 90-degree angled palm allows the cable to approach the connection point from the side, making the terminal suitable for confined spaces and installations where straight cable routing is impractical.

How should the Cembre A2-L5 be installed?

The conductor should be stripped to the recommended length, inserted fully into the barrel and crimped using a compatible professional compression tool with the correct die for a 10 mm² conductor.
