## Summary description

Ring terminal ELS Elektrotechnika SE-02508 is a copper, tin-plated electrical lug designed for crimping on 25 mm² conductors and fastening to M8 studs. It provides a reliable mechanical and electrical connection for power and grounding applications in automotive, industrial, and building electrical installations. Suitable for use with copper cables and standard crimping tools.

## Long description

Ring terminal ELS Elektrotechnika SE-02508 is a tin-plated copper lug designed to be crimped onto 25 mm² copper conductors and secured to M8 studs. The terminal provides a low-resistance electrical contact and a robust mechanical connection suitable for power distribution, grounding, and bonding applications in automotive, industrial and building electrical installations. The tin plating improves corrosion resistance and solderability compared with bare copper, while the ring design ensures a stable, vibration-resistant fastening to threaded posts or studs.
Advantages
The tin-plated copper construction combines high conductivity with enhanced corrosion protection, ensuring long-term electrical performance in exposed or humid environments. The ring form factor offers reliable mechanical retention on M8 studs, reducing the risk of loosening under vibration. The barrel is sized for 25 mm² conductors and is compatible with standard crimping tools, enabling straightforward installation and consistent crimp quality when the correct tooling and technique are used.
Suitable for
 Power distribution and busbar connections in vehicles and machinery
 Battery and grounding connections requiring M8 stud termination
 Industrial control panels and electrical cabinets
 Building electrical installations where a secure stud-mounted lug is needed
Key specifications
 Material: copper with tin plating
 Conductor cross-section suitability: 25 mm²
 Stud size compatibility: M8
 Terminal type: ring / lug for crimp connection
 Typical applications: power, grounding, bonding
How to use
Prepare the copper conductor by stripping the insulation to the appropriate length for full insertion into the barrel. Insert the conductor fully into the terminal barrel and use a suitable crimping tool sized for 25 mm² terminals to make a secure crimp according to the tool manufacturer’s instructions. After crimping, place the ring over the M8 stud and secure it with the appropriate nut and washer, applying the recommended torque for the stud and connection type to ensure a reliable mechanical and electrical joint.
Usage recommendations
For optimal performance, use the terminal with copper conductors only, and select a crimping die and tool rated for 25 mm² to achieve the correct compression. Inspect crimps visually and mechanically; where necessary, apply anti-corrosion compounds on exposed connections in aggressive environments and follow equipment manufacturer torque specifications when fastening to M8 studs.
