## Summary description

The Ergom B311 ring terminal is designed for reliable electrical connections via soldering. Featuring a 25mm² cross-section and an 8mm hole diameter, this terminal ensures secure mounting for power cables and grounding applications. Manufactured from high-quality materials, it provides excellent conductivity and durability for professional electrical installations and industrial wiring projects.

## Long description

The Ergom B311 ring terminal is a professional-grade component engineered for secure electrical connections through soldering. Designed specifically for 25mm² cross-section cables, this terminal features an 8mm mounting hole, making it an ideal choice for power distribution, grounding systems, and industrial wiring projects where a permanent, low-resistance connection is required.
Advantages
This ring terminal offers exceptional electrical conductivity due to its high-quality material composition, ensuring minimal power loss and reliable performance under load. Its robust design provides a stable mechanical connection that resists vibration and environmental stress, which is critical for maintaining long-term integrity in electrical installations. The soldering-ready surface allows for a clean and efficient bonding process, resulting in a durable connection that outperforms standard crimp-only alternatives in specific high-reliability applications.
Suitable for
Power cable terminations in industrial control panels
Grounding and earthing connections
Automotive and marine electrical systems
Heavy-duty electrical equipment wiring
When it may not be suitable
This terminal is not intended for applications requiring cold-crimp connections, as it is specifically optimized for soldering. It may also be unsuitable for environments where the cable cross-section does not match the 25mm² specification or where the mounting bolt size significantly differs from the 8mm diameter.
Key specifications
Cable cross-section: 25mm²
Mounting hole diameter: 8mm
Connection type: Soldering
Material: High-conductivity metal alloy
How to use
To use the Ergom B311 terminal, first strip the insulation from the end of your 25mm² cable to match the depth of the terminal barrel. Insert the conductor into the terminal and apply appropriate soldering equipment to heat the joint. Once the solder has flowed evenly into the connection, allow it to cool completely without movement to ensure a solid bond. Finally, secure the terminal to the desired surface using an M8 bolt, ensuring the connection is tightened to the manufacturer's torque specifications for the bolt size.
What to consider before purchase
Verify that your cable cross-section is exactly 25mm² for a proper fit.
Ensure that the mounting surface accommodates an M8 bolt.
Confirm that you have the necessary soldering equipment capable of handling the thermal mass of a 25mm² terminal.
Usage recommendations
Always ensure that the connection point is clean and free of oxidation before soldering to achieve the best electrical contact. Use heat-shrink tubing over the soldered joint to provide additional insulation and mechanical strain relief for the cable.
