Copper Ring Terminal Ergom KM 240/12 (model E11KM-01010108300) for cable termination

Ergom KM 240/12 is a copper ring terminal designed for secure cable termination and bolted electrical connections. The terminal provides a ring-style contact that ensures a stable mechanical and electrical link between insulated or bare conductors and fastening points. Constructed from corrosion-resistant copper, it is suitable for installations where low contact resistance and long-term reliability are required.

Advantages

The copper construction offers good electrical conductivity and resistance to oxidation, contributing to reliable current transfer and reduced power loss. The ring contact design allows firm bolted fastening, minimising the risk of loosening under vibration. The terminal is manufactured to provide consistent dimensions and fit, simplifying installation and ensuring repeatable performance in electrical panels, machinery, and wiring assemblies.

Suitable for

• Termination of copper conductors in distribution panels and switchboards
• Bolted connections on busbars, grounding points, and chassis
• Wiring assemblies in industrial machinery and control cabinets
• Field and workshop crimping applications where a ring-style lug is required

Key specifications

• Material: copper (corrosion-resistant finish)
• Contact style: ring terminal for bolted connections
• Cable accommodation: designed for compatible conductor cross-sections (as per product size)
• Mechanical fastening: suitable for bolting or stud mounting
• Electrical properties: low contact resistance for effective current transfer

How to use

Strip the cable insulation to the appropriate length for the terminal barrel, insert the conductor fully into the barrel, and crimp using a suitable crimping tool sized for the terminal and conductor. Place the ring over the mounting stud or bolt, and tighten the fastening hardware to the recommended torque for the application to ensure a secure, low-resistance connection. Where required, apply appropriate insulation or heat-shrink tubing to exposed areas to prevent accidental contact.

Usage recommendations

For reliable performance, select a terminal size that matches the conductor cross-section and the stud or bolt diameter. Use a quality crimping tool sized for the terminal to achieve a proper crimp profile. Verify tightness of bolted connections after initial installation and during maintenance; avoid mixing dissimilar metals without appropriate protection to prevent galvanic corrosion.
