Ring Cable Lug Ergom KOR 35/10 tinned copper (MPN E11KM-01020104100)

Ergom KOR 35/10 tinned copper ring cable lug is designed for reliable termination of 35 mm² conductors to stud-type terminals with a 10 mm bolt hole. The lug combines a shaped barrel for secure conductor insertion and a flat ring for stable bolted connection, with a tin-plated finish to improve corrosion resistance and electrical contact. It is intended for use in power distribution, switchgear, control panels and a variety of industrial electrical installations where a compact, durable mechanical and electrical connection is required.

Advantages

The tinned copper construction offers low electrical resistance and improved conductivity compared with many plated alternatives, while the tin plating adds extra protection against oxidation in typical indoor and some outdoor applications. The lug’s barrel is shaped to accept insulated or stripped 35 mm² conductors and can be crimped or compressed with compatible tooling for a secure mechanical and electrical joint. The flat ring terminal and standard 10 mm bolt hole enable straightforward mounting to stud-type terminals, busbars or other bolted connections.

Suitable for

• Termination of 35 mm² single-core or multi-strand copper conductors
• Bolted connections to stud terminals, busbars and distribution blocks with a 10 mm bolt
• Use in switchgear, distribution panels and control cabinets
• Industrial and commercial electrical installations requiring corrosion-resistant lugs

When it may not be suitable

This lug is intended specifically for 35 mm² conductors and a 10 mm bolt hole; it is not suitable for conductors of significantly different cross-section or for bolts of other diameters without adapter hardware. It is a passive mechanical connector and does not provide insulation, overcurrent protection, or strain relief by itself, so additional measures (insulation sleeves, heat-shrink, protective covers, or cable clamps) may be required depending on the application and safety standards.

Key specifications

• Conductor cross-section compatibility: 35 mm²
• Material: copper with tin plating
• Bolt hole diameter: 10 mm
• Terminal type: ring (eye) lug for stud mounting
• Connection method: crimp/compression compatible barrel

How to use

Strip the conductor to the correct length and insert the bare conductor fully into the lug barrel. Use a suitable crimping or compression tool rated for 35 mm² lugs to form a gas-tight mechanical connection. After crimping, inspect the joint for correct compression and ensure no stray strands are protruding. Mount the ring terminal onto the stud or bolt and tighten the nut to the recommended torque for the installation to ensure secure electrical contact. Where required, apply insulating sleeves or heat-shrink tubing and secure the cable with appropriate clamps to provide strain relief.

What to consider before purchase

• Verify conductor cross-section is 35 mm² and compatible with crimping tools you have available
• Confirm your stud or bolt diameter is 10 mm for direct mounting
• Consider required environmental protection and whether additional insulation or sealing is needed
• Ensure chosen crimping tool and dies are rated for tinned-copper lugs and the specified conductor size

Usage recommendations

Use industry-standard crimping or compression tools sized for 35 mm² to achieve a reliable, low-resistance joint. For outdoor or corrosive environments, inspect connections periodically and consider additional protective measures such as insulating boots or corrosion-inhibiting compounds.
