## Summary description

The Ergom B311 is a high-quality solderable ring terminal designed for reliable electrical connections. With a cross-section of 50mm² and an M10 mounting hole, this terminal ensures optimal conductivity and secure attachment for power cables. Ideal for professional electrical installations, automotive wiring, and industrial equipment where a permanent, soldered connection is required for enhanced durability.

## Long description

The Ergom B311 solderable ring terminal is a professional-grade electrical component engineered for high-performance connectivity in demanding environments. Designed for cables with a cross-section of 50mm², this terminal provides a robust interface for power distribution and grounding applications. Its construction allows for a permanent, soldered connection, which minimizes electrical resistance and ensures long-term stability for critical electrical systems.
Advantages
The primary benefit of the Ergom B311 terminal is its ability to facilitate a secure, low-resistance connection through the soldering process, which is superior to standard crimping in high-vibration or high-temperature environments. The high-quality material composition ensures excellent electrical conductivity and resistance to corrosion, maintaining signal integrity over time. Its precise M10 mounting hole design allows for easy and reliable installation onto busbars, battery terminals, or chassis studs, providing a mechanical connection that remains stable under heavy electrical loads.
Suitable for
Industrial power distribution panels
Automotive battery cable terminations
Heavy-duty electrical machinery wiring
Grounding systems in professional installations
When it may not be suitable
This terminal is not intended for applications where a crimped connection is preferred or required by specific safety standards. It is also not suitable for use with cables that do not match the 50mm² cross-section, as improper sizing can lead to overheating or mechanical failure.
Key specifications
Cable cross-section: 50mm²
Mounting hole diameter: M10
Connection type: Solderable
Material: High-conductivity copper alloy
How to use
To install the Ergom B311, first strip the insulation from the end of your 50mm² cable to match the depth of the terminal barrel. Insert the conductor into the terminal and apply appropriate soldering equipment to heat the terminal and the wire. Feed high-quality solder into the joint until the gap is completely filled, ensuring a solid bond. Once the connection has cooled, secure the terminal to the M10 mounting point using a compatible bolt and washer, ensuring the connection is tightened to the manufacturer's specified torque.
What to consider before purchase
Verify that your cable cross-section is exactly 50mm²
Ensure you have the necessary soldering equipment capable of heating a terminal of this size
Check the mounting stud size to ensure compatibility with the M10 hole
Usage recommendations
Always ensure the connection surface is clean and free of oxidation before soldering to achieve the best electrical contact. Use appropriate heat-shrink tubing over the soldered joint to provide additional insulation and mechanical strain relief for the cable.
