Ergom KO 70/10 Tinned Copper Ring Terminal

The Ergom KO 70/10 tinned copper ring terminal is a professional-grade component engineered for secure and efficient electrical terminations. Designed to accommodate copper conductors with a cross-section of 70 mm², this terminal features a 10 mm stud hole, making it compatible with standard mounting bolts in power distribution systems. The high-quality copper construction ensures excellent electrical conductivity, while the tin plating provides a robust barrier against oxidation and corrosion, extending the service life of the connection in demanding environments.

Advantages

This ring terminal offers superior mechanical strength and electrical performance due to its high-purity copper base. The precision-engineered design ensures a tight fit, minimizing contact resistance and preventing overheating during high-current operations. Its tinned surface treatment is specifically chosen to maintain long-term reliability, even in humid or chemically active industrial atmospheres, ensuring that the connection remains stable over time.

Suitable for

• Industrial power distribution panels
• Commercial electrical infrastructure
• Heavy-duty machinery wiring
• Battery cable terminations
• Grounding connections

When it may not be suitable

This terminal is not intended for use with aluminum conductors, as this can lead to galvanic corrosion and connection failure. It is also not suitable for applications requiring high-temperature resistance beyond the standard limits of copper and tin materials, or for connections where the stud size significantly deviates from the 10 mm specification.

Key specifications

• Material: Tinned copper
• Conductor cross-section: 70 mm²
• Stud hole diameter: 10 mm
• Connection type: Ring terminal

How to use

To install the terminal, first strip the insulation from the copper conductor to the appropriate length. Insert the conductor into the barrel of the terminal and use a professional crimping tool designed for 70 mm² terminals to create a permanent, gas-tight connection. Once crimped, place the ring over the corresponding stud and secure it firmly with a nut and washer to ensure optimal contact pressure.

What to consider before purchase

• Verify the cross-section of your copper cable matches the 70 mm² rating.
• Ensure the mounting stud diameter is exactly 10 mm.
• Use the correct crimping die set for this specific terminal size.
• Confirm the environmental conditions are suitable for tinned copper.

Usage recommendations

Always use a calibrated crimping tool to ensure the integrity of the connection. Avoid over-tightening the mounting nut to prevent mechanical stress on the terminal ring.
