Erko KCZ Copper Tubular Ring Terminal M8 for 35mm² Conductors

The Erko KCZ copper tubular ring terminal is a professional-grade connector engineered for the secure termination of 35mm² copper conductors. Designed with precision, this terminal features an M8 stud hole, making it compatible with standard electrical hardware. Its tubular construction ensures a robust mechanical bond and excellent electrical conductivity, which is essential for maintaining system integrity in demanding environments.

Advantages

This terminal offers superior performance due to its high-quality copper material, which minimizes resistance and prevents overheating at the connection point. The design facilitates a reliable crimping process, ensuring that the conductor remains firmly in place even under vibration or thermal expansion. Its durable build quality provides long-term stability for critical electrical circuits, reducing the need for frequent maintenance or replacements in power distribution systems.

Suitable for

• Electrical switchgear assembly
• Power distribution panels
• Industrial machinery wiring
• Grounding connections
• Heavy-duty electrical installations

When it may not be suitable

This terminal is specifically designed for copper conductors and should not be used with aluminum wires due to the risk of galvanic corrosion. It is also not intended for applications requiring high-temperature insulation or specialized environmental sealing beyond standard electrical enclosures.

Key specifications

• Conductor cross-section: 35mm²
• Stud hole diameter: M8
• Material: High-conductivity copper
• Connection type: Tubular ring terminal

How to use

To install the terminal, first strip the insulation from the end of the 35mm² copper conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool compatible with this specific terminal size to apply uniform pressure, ensuring a gas-tight connection. Once crimped, the terminal can be secured to the M8 stud using a matching nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.

What to consider before purchase

• Verify the conductor cross-section matches the 35mm² specification.
• Ensure the M8 stud size is compatible with your existing equipment.
• Confirm that you have the correct crimping tool for tubular copper terminals.
• Check that the installation environment is free from corrosive elements that could affect copper.

Usage recommendations

Always ensure that the crimping tool is properly calibrated for the terminal size to achieve a secure and permanent electrical connection. Regularly inspect connections in high-vibration environments to ensure they remain tight over time.
