## Summary description

The EM Group KN50/8 tubular ring terminal is designed for reliable electrical connections of 50mm² copper conductors. Featuring an M8 stud hole, this unplated copper terminal ensures excellent conductivity and durability in industrial and electrical installations. It is ideal for secure cable termination in power distribution systems, switchgear, and grounding applications.

## Long description

The EM Group tubular ring terminal is a high-quality electrical component engineered for the secure and efficient termination of 50mm² copper conductors. Designed with precision, this terminal features an M8 stud hole, making it compatible with standard electrical hardware. Constructed from high-grade unplated copper, it provides superior electrical conductivity and mechanical strength, ensuring long-term reliability in demanding electrical environments.
Advantages
This tubular ring terminal offers exceptional performance due to its robust copper construction, which minimizes resistance and prevents overheating in high-current applications. The design facilitates a strong, permanent connection when crimped correctly, providing excellent vibration resistance and structural integrity. Its unplated surface is ideal for specific industrial requirements where pure copper contact is preferred for optimal electrical transfer.
Suitable for
Power distribution systems
Switchgear and control panels
Grounding and earthing applications
Industrial electrical installations
Heavy-duty cable termination
This terminal may not be suitable for environments with high levels of humidity or corrosive atmospheres, as the unplated copper surface is susceptible to oxidation over time. It is also not intended for use with aluminum conductors, as this can lead to galvanic corrosion.
Key specifications
Conductor cross-section: 50mm²
Stud hole diameter: M8
Material: Unplated copper
Type: Tubular ring terminal
To use this terminal, first strip the insulation from the end of the 50mm² copper cable to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Using a professional-grade hydraulic or manual crimping tool designed for this specific size, apply sufficient pressure to create a cold-welded connection between the terminal and the wire. Ensure the crimp is tight and secure before installing the terminal onto the M8 stud and tightening the nut to the manufacturer's specified torque.
What to consider before purchase
Ensure the cable cross-section matches the 50mm² rating exactly.
Verify that the M8 stud size is compatible with your existing equipment.
Check if your installation environment requires tin-plated terminals for corrosion protection.
Confirm you have access to the correct crimping tool for 50mm² terminals.
Usage recommendations: Always use a calibrated crimping tool to ensure a proper connection. Regularly inspect the connection point for signs of oxidation or heat damage, especially in high-load systems.
