Why Choose the Cembre 2190160 A5-M8/13.5 Narrow-Palm Copper Ring Terminal?
The Cembre 2190160, also designated as the Cembre A5-M8/13.5, is a professional non-insulated copper compression ring terminal designed to terminate 25 mm² copper conductors onto M8 threaded studs. Its contained 13.5 mm narrow palm makes it especially suitable for compact circuit breakers, switchgear and equipment terminals that cannot accommodate a standard-width cable lug.
Manufactured from high-purity electrolytic copper tube, the Cembre A5-M8/13.5 provides excellent electrical conductivity and the mechanical strength required to resist vibration and conductor pull-out. The terminal is annealed to ensure optimum ductility during compression and electrolytically tin plated to improve resistance to oxidation, corrosion and mechanical stress.
The Cembre 2190160 features a short-barrel design, an internally chamfered conductor entry and an integrated inspection hole. These features simplify cable insertion, help prevent damage to individual conductor strands and allow installers to verify that the conductor is fully positioned before crimping.
Key Advantages
- Designed for reliable termination of 25 mm² copper conductors.
- 13.5 mm contained palm fits compact equipment terminals.
- M8 stud compatibility for secure bolted connections.
- High-purity electrolytic copper provides excellent conductivity.
- Annealed construction supports dependable compression crimping.
- Electrolytic tin plating improves oxidation and corrosion resistance.
Key Features
- Cembre narrow-connection copper compression terminal.
- Manufacturer part number: 2190160.
- Terminal designation: A5-M8/13.5.
- 25 mm² / approximately 4 AWG conductor compatibility.
- M8 ring fixing configuration.
- 13.5 mm contained-palm width.
- Short barrel with an easy-entry internal chamfer.
- Inspection hole for conductor-position verification.
Designed for Compact Electrical Connection Points
Contained-palm compression terminals are designed for equipment where conventional cable lugs are too wide for the available connection space. The reduced palm width of the Cembre A5-M8/13.5 enables a 25 mm² conductor to be connected securely to an M8 terminal while maintaining the electrical and mechanical performance expected from a professional copper compression lug.
When installed using a compatible Cembre crimping tool and the correct die, the terminal produces a permanent, low-resistance connection capable of withstanding vibration, thermal cycling and mechanical stress. Its compact dimensions make it particularly useful in modern switchgear and control equipment with closely spaced terminals.
Typical Applications
- Low-voltage circuit breakers.
- Compact switchgear assemblies.
- Industrial control panels and electrical cabinets.
- Motor control centres.
- Power-distribution equipment.
- OEM machinery and automation systems.

Frequently Asked Questions
What is the Cembre 2190160 used for?
The Cembre 2190160 is used to terminate 25 mm² copper conductors onto M8 threaded studs, particularly in compact switchgear and circuit-breaker terminals.
What does A5-M8/13.5 mean?
A5 identifies the terminal size for a 25 mm² conductor, M8 identifies the compatible stud size and 13.5 refers to the terminal's contained palm width.
Why does the Cembre 2190160 have a narrow palm?
The 13.5 mm contained palm allows the terminal to fit connection points that are too narrow for a conventional full-width copper ring terminal.
Does the Cembre A5-M8/13.5 include an inspection hole?
Yes. The barrel incorporates an inspection hole so the installer can confirm that the conductor has been fully inserted before crimping.
How should the Cembre 2190160 be installed?
The conductor should be stripped to the appropriate length, inserted fully into the chamfered barrel and compressed using a compatible professional crimping tool with the correct die for a 25 mm² terminal.
