Ergom aluminum ring terminal 2KAM 25/10 (E12KA-01050100600) - cable lug for crimping

Ergom aluminum ring terminal 2KAM 25/10 is a crimp-type cable lug engineered for making reliable bolted or screwed connections in electrical systems. Constructed from aluminum, the terminal has a ring (eye) end for secure mechanical fastening and a tubular barrel for conductor insertion and mechanical crimping. It is intended for power and grounding circuits where a compact, conductive and corrosion-resistant terminal is required.

Advantages

The aluminum construction offers a good balance of electrical conductivity and corrosion resistance while keeping weight low. The ring-style end provides a stable, vibration-resistant fastening point suitable for bolted or screwed connections. The tubular barrel is sized to accept the specified conductor cross-section and is designed for crimping with standard crimping tools, creating a secure mechanical and electrical joint.

Suitable for

• Power distribution and feeder cables with matching conductor cross-section
• Grounding and earthing connections in electrical panels and equipment
• Automotive, marine, and industrial electrical installations where aluminum terminals are specified
• Fixed installations requiring bolted or screwed terminal connections

When it may not be suitable

This aluminum ring terminal is not appropriate where only copper terminals are specified by code or where direct contact with dissimilar metals without appropriate anti-oxidation treatment could cause galvanic corrosion. It may also be unsuitable for conductors that do not match the terminal's stated conductor size or for applications requiring insulated or sealed terminations.

Key specifications

• Material: aluminum
• Contact style: ring (eye) terminal
• Conductor accommodation: designed for 25 mm² conductor cross-section
• Bolt hole diameter: sized for M10 (10 mm) fastening
• Termination method: crimping into tubular barrel

How to use

Prepare the conductor by stripping insulation to the recommended length, ensuring the exposed conductor matches the barrel length. Insert the conductor fully into the tubular barrel. Use an appropriate crimping tool and die rated for the conductor cross-section and aluminum terminals; perform a controlled crimp to produce a solid mechanical and electrical connection. After crimping, attach the ring end to the mating stud or bolt and secure with the specified nut and washer. If the installation will expose dissimilar metals, apply an anti-oxidation compound where required and ensure secure mechanical protection against moisture and movement.

What to consider before purchase

• Verify conductor cross-section compatibility (25 mm²)
• Confirm bolt/hole size requirements (10 mm) for mating hardware
• Ensure aluminum terminals are acceptable for the intended environment and code
• Check that you have the correct crimping tool and die for aluminum lugs

Usage recommendations

Use a crimping tool and die set rated for aluminum terminals and the specified conductor size, inspect crimp quality visually and mechanically, and protect any dissimilar metal joints with appropriate anti-oxidation treatment or insulation to prevent corrosion and ensure long-term reliability.
