## Summary description

The EM Group tubular ring terminal (KN25/10) is designed for reliable electrical connections of 25mm² conductors. Featuring an M10 stud hole, this terminal is manufactured from high-quality unplated copper, ensuring excellent conductivity and durability in professional electrical installations. It is ideal for secure termination in power distribution cabinets, grounding systems, and industrial wiring applications.

## Long description

The EM Group tubular ring terminal is a high-quality electrical component engineered for the secure termination of 25mm² conductors. Designed with an M10 stud hole, this terminal is crafted from premium unplated copper, providing superior electrical conductivity and mechanical strength. It serves as a reliable solution for establishing permanent, low-resistance connections in demanding electrical environments.
Advantages
This tubular ring terminal offers exceptional performance due to its robust construction from high-purity copper. The unplated finish ensures optimal contact surfaces for electrical current flow, minimizing energy loss and heat generation. Its tubular design allows for easy insertion of the conductor, facilitating a strong crimped connection that resists vibration and mechanical stress, making it a dependable choice for long-term electrical infrastructure projects.
Suitable for
Power distribution cabinets and switchgear
Grounding and earthing systems
Industrial electrical wiring and machinery
Battery cable connections
When it may not be suitable
This terminal is not intended for use in highly corrosive environments where oxidation of unplated copper could occur, as it lacks a protective tin coating. It is also not suitable for applications requiring aluminum conductors without the use of appropriate bimetallic transition adapters.
Key specifications
Conductor cross-section: 25mm²
Stud hole diameter: M10
Material: Unplated copper
Design: Tubular ring type
How to use
To install the terminal, first strip the insulation from the 25mm² conductor to the appropriate length. Insert the conductor fully into the tubular barrel of the terminal. Use a professional-grade crimping tool compatible with the terminal size to compress the barrel firmly onto the wire, ensuring a gas-tight connection. Once crimped, secure the ring end onto the M10 stud using a suitable nut and washer, ensuring the connection is tightened to the manufacturer's recommended torque specifications.
What to consider before purchase
Verify the conductor cross-section matches the 25mm² rating
Ensure the M10 stud size is compatible with your connection point
Assess the environmental conditions to determine if unplated copper is appropriate
Ensure you have the correct crimping tool for tubular terminals
Usage recommendations
Always ensure the crimping tool is properly calibrated for the specific terminal size to guarantee a secure and safe electrical connection. Inspect the connection periodically for signs of oxidation or loosening in high-vibration environments.
