Ergom B311 Ring Terminal for Soldering 35mm² M8

The Ergom B311 ring terminal is a high-quality electrical component engineered for secure and permanent connections through soldering. Designed for cables with a 35mm² cross-section, this terminal features an 8mm mounting hole, making it compatible with M8 studs and bolts. Its construction focuses on maintaining optimal electrical conductivity and mechanical stability, which is critical for demanding industrial and automotive environments where vibration and thermal stress are common factors.

Advantages

This ring terminal offers excellent electrical performance due to its design, which facilitates a strong solder bond between the cable and the terminal body. The robust material composition ensures long-term durability and resistance to environmental factors, providing a reliable termination point that minimizes resistance and prevents overheating. Its precise dimensions allow for consistent installation, ensuring that electrical systems remain stable and efficient over extended periods of operation.

Suitable for

• Industrial electrical panel wiring
• Automotive power distribution systems
• Heavy machinery electrical maintenance
• Battery cable terminations
• Grounding connections in electrical installations

When it may not be suitable

This terminal is specifically designed for soldering applications and may not be suitable for environments where crimping is the required installation method. It is also not intended for use with cables that fall outside the specified 35mm² cross-section range, as this could lead to poor electrical contact or mechanical failure.

Key specifications

• Cable cross-section: 35mm²
• Mounting hole diameter: 8mm
• Connection type: Soldering
• Material: High-conductivity metal

How to use

To install the Ergom B311 ring terminal, first strip the insulation from the end of the 35mm² cable to match the depth of the terminal's barrel. Clean the conductor surface to ensure a proper bond. Insert the cable into the terminal and apply appropriate soldering equipment to heat the connection point, allowing the solder to flow evenly between the conductor and the terminal. Once the solder has cooled and solidified, ensure the connection is rigid before securing the terminal to the M8 stud using a compatible nut and washer.

What to consider before purchase

• Verify the cable gauge matches the 35mm² requirement
• Ensure the M8 bolt size is compatible with the 8mm hole
• Confirm that soldering equipment is available for installation
• Check the environmental conditions to ensure the material is appropriate for the application

Usage recommendations

Always ensure the cable is fully inserted into the terminal barrel before soldering to maximize the contact surface area and mechanical strength of the connection.
