Ergom B311 Solderable Ring Terminal 50mm² M10

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.
