Erko KCZ Tubular Copper Ring Terminal M8 for 150mm² Cable

The Erko KCZ tubular copper ring terminal is a professional-grade component engineered for secure and efficient electrical terminations of 150mm² conductors. Designed with precision, this terminal features an M8 stud hole, providing a robust connection point for power distribution systems and industrial electrical infrastructure. Its tubular construction ensures excellent contact surface area, which is essential for maintaining low electrical resistance and high mechanical integrity in demanding environments.

Advantages

This terminal is manufactured from high-quality copper, which offers superior electrical conductivity and corrosion resistance. The design is specifically optimized for heavy-duty applications, ensuring that the connection remains stable under varying thermal and mechanical loads. By utilizing this terminal, installers can achieve a permanent, reliable bond that minimizes the risk of overheating or connection failure in critical power circuits.

Suitable for

• Power distribution cabinets and switchgear
• Industrial electrical wiring projects
• Heavy-duty electrical installations requiring M8 stud connections
• Connecting 150mm² copper conductors to busbars or equipment terminals

When it may not be suitable

This terminal is not intended for use with aluminum conductors, as galvanic corrosion may occur. It is also not suitable for applications requiring a different stud size than M8 or for cables with a cross-section other than 150mm².

Key specifications

• Material: High-conductivity copper
• Conductor cross-section: 150mm²
• Stud hole diameter: M8
• Design: Tubular ring terminal

How to use

To install the terminal, first strip the insulation from the 150mm² cable to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional hydraulic or mechanical crimping tool compatible with this specific terminal size to ensure a proper cold-weld connection. Once crimped, secure the ring terminal to the 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 the cable cross-section is exactly 150mm²
• Ensure the equipment stud size matches the M8 terminal hole
• Confirm that the appropriate crimping tool is available for installation

Usage recommendations

Always ensure that the crimping tool dies match the terminal size to prevent under-crimping or damage to the copper barrel. Regularly inspect connections in high-vibration environments to ensure the nut remains tight.
