Erko KCZ Copper Tubular Ring Terminal M8 for 70mm² Cable

The Erko KCZ copper tubular ring terminal is a professional-grade component engineered for the secure termination of 70mm² copper conductors. Designed with precision, this terminal features an M8 stud hole, making it compatible with a wide range of standard electrical hardware. Its tubular construction provides a robust connection point that maintains excellent electrical conductivity and mechanical integrity under various operating conditions.

Advantages

This terminal is manufactured from high-quality copper, which offers superior electrical performance and resistance to corrosion when properly installed. The tubular design allows for a deep, secure crimp, ensuring that the conductor remains firmly attached to the terminal even under vibration or thermal expansion. By providing a reliable interface between the cable and the terminal block or busbar, it minimizes resistance and prevents overheating in power distribution circuits.

Suitable for

• Professional electrical installations
• Power distribution systems
• Industrial wiring applications
• Heavy-duty electrical equipment connections

When it may not be suitable

This terminal is specifically designed for 70mm² copper conductors and is not suitable for use with aluminum cables, as this can lead to galvanic corrosion. It is also not intended for applications where the stud size exceeds M8 or where the environment requires specialized insulation or environmental sealing beyond standard electrical practices.

Key specifications

• Material: High-quality copper
• Cable cross-section: 70mm²
• Stud hole diameter: M8
• Terminal type: Tubular ring

How to use

To install the terminal, first strip the insulation from the end of the 70mm² copper cable to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade hydraulic or manual crimping tool specifically calibrated for this terminal size to create a secure, permanent connection. Ensure the crimp is centered on the barrel for maximum mechanical strength. Once crimped, the terminal can be bolted onto an M8 stud using a suitable nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify that your cable cross-section is exactly 70mm².
• Ensure the mounting stud size is M8.
• Confirm that you have access to the correct crimping tool for this terminal type.
• Check that the environment is compatible with uninsulated copper components.

Usage recommendations

Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid reusing terminals after they have been crimped, as the mechanical deformation during the initial installation compromises the structural strength of the metal for subsequent uses.
