Copper ring terminal Ergom KM 70/12 10 pcs — closed eyelet for cable lugs, 70 mm², 12 mm bore

Ergom KM 70/12 copper ring terminals, supplied in packs of 10, are closed eyelet cable lugs designed for crimping to 70 mm² conductors and securing with a 12 mm bolt. Manufactured from conductive copper, these ring terminals provide a low-resistance electrical path and mechanical stability for heavy current connections. They are intended for fixed, crimped terminations where a reliable bolted contact is required.

Advantages

These copper ring terminals deliver consistent electrical conductivity and reduced contact resistance due to their copper construction. The closed-eye design ensures a solid mechanical connection that resists loosening under vibration when properly crimped and bolted. Supplied in a set of 10, they offer a straightforward solution for multiple terminations and reduce preparation time in installations. The terminals are compatible with standard crimping tools for the specified conductor cross-section.

Suitable for

• Battery cable terminations in vehicles and stationary battery systems
• Grounding and earthing connections in electrical installations
• Power distribution blocks and busbar connections
• Heavy current circuits and industrial equipment requiring crimped lugs

Key specifications

• Material: conductive copper
• Conductor cross-section compatibility: 70 mm²
• Bolt hole diameter: 12 mm
• Design: closed eyelet (ring) for bolted connections
• Package quantity: 10 pieces

How to use

Select a copper ring terminal that matches the conductor cross-section and bolt diameter. Strip the insulation from the conductor to the appropriate length, insert the conductor fully into the terminal barrel, and perform a crimp with a suitable crimping tool or hydraulic crimper designed for 70 mm² lugs. After crimping, position the ring over the bolt and tighten the bolt to the torque specified for the mating terminal or connection point to ensure a secure, low-resistance joint. Inspect the crimp and bolted connection for mechanical security and correct alignment before energizing the circuit.

Usage recommendations

Use appropriately sized crimp dies and follow recommended torque values for bolted connections to maintain electrical performance and mechanical integrity. Apply anti-corrosion treatment or protective covers where terminals are exposed to moisture or corrosive environments. For critical or high-current installations, check connections periodically for tightness and signs of heating or corrosion.
