Ergom ring terminal copper tinned KOR 70/12 model E11KM-01020105500

Ergom ring terminal copper tinned KOR 70/12 model E11KM-01020105500 is a tin-plated copper ring lug designed to provide a durable and low-resistance electrical connection for bolted terminations. The ring-style construction ensures stable contact when secured under a bolt or stud, while the tin plating improves corrosion resistance and solderability. This terminal is intended for use with appropriately sized stranded copper conductors and is commonly applied in switchgear, battery connections, distribution blocks and industrial electrical installations where a mechanically secure and conductive lug is required.

Advantages

The tin-plated copper material combines high conductivity with enhanced protection against oxidation, reducing contact resistance over time. The ring configuration ensures reliable mechanical retention under bolts or studs and simplifies assembly in confined or vibration-prone environments. The product is suitable for crimping or soldering, offering flexibility for different installation practices while maintaining a compact and robust profile that fits standard terminal mounting hardware.

Suitable for

• Bolted terminations on switchgear and distribution panels
• Battery terminals and power distribution in vehicles or stationary systems
• Industrial equipment and control cabinets requiring durable electrical lugs
• Connections where crimping or soldering of stranded copper conductors is performed

When it may not be suitable

This ring terminal is intended for use with copper conductors of the appropriate cross-section and may not be suitable for aluminum conductors unless a suitable transition method and anti-oxidation treatment are used. It is not a sealed or waterproof terminal, so it may not be appropriate for continuous immersion or highly corrosive outdoor environments without additional protection. Always verify conductor size and bolt diameter compatibility before selection.

Key specifications

• Material: copper with tin plating for corrosion resistance
• Terminal type: ring lug for bolted connections
• Conductor compatibility: designed for stranded copper conductors of matching cross-section
• Mechanical attachment: secured under a bolt or stud using the ring aperture
• Suitable termination methods: crimping or soldering

How to use

Strip the insulation from the conductor to the length required for full insertion into the barrel of the ring terminal. Insert the stranded copper conductor into the barrel, ensuring all strands are contained. Use an appropriately sized crimping tool and die to compress the barrel onto the conductor following crimp manufacturer guidelines; alternatively, solder the conductor into the barrel if soldering is preferred and appropriate for the application. Place the ring over the bolt or stud, then secure with the specified nut and torque value for the application to ensure a reliable electrical and mechanical connection.

What to consider before purchase

• Confirm conductor cross-section compatibility with the terminal's rated range
• Ensure the bolt or stud diameter matches the ring aperture size
• Decide between crimping or soldering as the termination method and confirm tool availability
• Assess the environmental conditions (moisture, corrosion) and plan additional protection if needed

Usage recommendations

Use appropriate crimping tools sized for the barrel and follow industry-standard torque specifications for the bolt or stud to maintain a low-resistance, long-term connection. For outdoor or corrosive environments, apply additional sealing or protective measures. Avoid mixing copper and aluminum conductors directly; use approved bi-metallic connectors or transition methods when required.
