Copper ring terminal Ergom KM 185/12 — insulated copper lug for cable termination

Ergom KM 185/12 is a copper ring terminal designed for secure cable termination and bolted connections. This insulated copper lug provides a stable electrical contact between conductor and terminal point, suitable for connections to busbars, studs or grounding points. The ring shape ensures a reliable mechanical and electrical joint when fastened with a bolt or screw, while the copper material offers good conductivity and corrosion resistance in typical electrical environments.

Advantages

The insulated design reduces the risk of accidental short-circuits and provides basic mechanical protection for the conductor termination. Copper construction ensures low electrical resistance and durable performance under normal operating conditions. The ring-form lug allows easy installation with standard fastening hardware and offers consistent contact surface area for repeatable, secure bolted connections.

Suitable for

• Electrical installations requiring bolted cable connections
• Control panels and switchgear terminations
• Grounding and earthing connections in machinery and vehicles
• Busbar and stud connections where a ring lug is required

Key specifications

• Material: Copper conductor with insulating sleeve
• Terminal type: Ring (round) lug for bolted connections
• Insulation: Partial sleeve for conductor protection
• Compatibility: Designed for use with stranded or solid copper conductors of the matching conductor cross-section
• Mounting: Fits on a bolt or stud with matching hole diameter

How to use

Strip the cable insulation to the appropriate length to insert the conductor fully into the lug barrel. Crimp the barrel using a suitable crimping tool matched to the conductor size and terminal type to achieve a secure mechanical and electrical connection. Slide the insulating sleeve over the crimped joint if not already in place. Position the ring over the bolt or stud, then fasten with the appropriate nut and washer to the recommended torque for the connection to ensure reliable contact.

Usage recommendations

Use correct conductor sizing and a certified crimping tool to ensure a durable connection. Verify compatibility of bolt/stud diameter and tighten to manufacturer-recommended torque values for the installation. Avoid excessive bending or mechanical stress at the termination point and perform periodic visual inspections for corrosion or loosened fasteners.
