Ergom B311 Solderable Ring Terminal 70mm² M10

The Ergom B311 solderable ring terminal is a professional-grade electrical component engineered for the secure termination of 70mm² cables. Designed for applications requiring high mechanical stability and excellent electrical conductivity, this terminal features a robust construction that facilitates a reliable soldered connection. With an M10 mounting hole, it is compatible with standard industrial studs and bolts, making it an essential part of power distribution and grounding infrastructure.

Advantages

This terminal offers superior performance due to its high-quality material composition, which ensures minimal resistance and long-term durability in demanding electrical environments. The design specifically supports soldering, which provides a permanent, low-resistance bond between the conductor and the terminal, effectively preventing oxidation and loosening over time. Its precise dimensions allow for consistent installation, contributing to the overall safety and efficiency of electrical systems.

Suitable for

• Power distribution cabinets and switchgear
• Grounding and earthing systems
• Industrial machinery electrical connections
• Heavy-duty automotive and marine power wiring

This terminal may not be suitable for applications where mechanical crimping is preferred or required by specific safety standards, as it is specifically designed for soldering. It is also not intended for use with cables outside the 70mm² specification, as improper sizing can lead to poor electrical contact and overheating.

Key specifications

• Cable cross-section: 70mm²
• Mounting hole diameter: 10mm (M10)
• Connection type: Solderable
• Material: High-conductivity metal

To use the Ergom B311 terminal, first strip the insulation from the end of the 70mm² cable to the appropriate length. Insert the conductor into the terminal barrel and apply the correct amount of solder using a suitable heating tool to ensure the metal flows evenly around the wire strands. Once the connection has cooled completely, mount the terminal onto the M10 stud and secure it firmly with a nut and washer to ensure optimal contact pressure.

What to consider before purchase

• Verify that your cable cross-section is exactly 70mm²
• Ensure your equipment supports M10 bolt sizes
• Confirm that you have the necessary soldering equipment for large-gauge wire
• Check local electrical regulations regarding the use of soldered versus crimped connections

For the best results, ensure the cable strands are clean and free of oxidation before soldering. Always use high-quality solder and ensure the connection is fully supported to prevent mechanical stress on the joint.
