SC Type Tinned Copper Cable Lugs

Reliable Cable Termination. Secure Bolted Connections. Multiple Sizes for Electrical Installations.

SC type copper cable lugs, also known as tubular copper crimp lugs or copper cable terminals, are designed to terminate copper conductors and connect them to busbars, circuit breakers, electrical equipment and bolted terminals.

Made from copper with a tin-plated surface, these non-insulated cable lugs feature a tubular crimp barrel and a flat, single-hole mounting palm.

Reliable Crimp & Bolted Connection

The tubular barrel provides a crimping area for the stripped copper conductor, while the flat ring palm allows secure fastening to a compatible stud or busbar connection.

Key advantages include:

• Copper Construction: Provides an electrically conductive connection path.
• Tin-Plated Surface: Helps reduce surface oxidation and supports consistent electrical contact.
• Tubular Crimp Barrel: Designed for mechanical compression using suitable crimping tools and dies.
• Flat Single-Hole Palm: Suitable for bolted connections to compatible equipment terminals.
• Multiple Cable & Stud Sizes: Different barrel dimensions and mounting holes for a wide range of installations.

SC Series Cable Lug Sizes

Available in multiple nominal conductor sizes, from 1.5 mm² to 1200 mm² across the catalog range, with different mounting hole options.

Common selections include SC10, SC16, SC25, SC35, SC50, SC70, SC95, SC120, SC150, SC185 and SC240, with additional sizes available.

Each model should be selected according to the conductor dimensions, stud size and required crimping method.

Typical Applications

• Power Distribution Panels: Copper cable connections to busbars and switching equipment.
• Industrial Machinery: Power cable termination inside electrical equipment.
• Electrical Installation: Bolted cable connections in suitable distribution systems.
• Motors & Control Equipment: Power connections to compatible equipment terminals.
• Maintenance & Repair: Replacement of worn or damaged cable terminations.

How to Choose the Right Cable Lug

Select the correct lug by checking the copper conductor cross-section, conductor construction, barrel inside diameter, stud hole diameter and crimping tool compatibility.

Use the specified crimping procedure and appropriate bolt tightening torque. Add suitable insulating protection wherever required by the installation.

Request a Quote: Please provide your cable size (mm²), stud size, required quantity and packaging requirements.

Model Example: SC25-8 indicates a cable lug for a nominal 25 mm² conductor with an M8 mounting hole. The actual hole diameter is 8.5 mm according to the size chart. Always verify conductor and crimping compatibility before installation.

Frequently Asked Questions

1. What are SC copper cable lugs used for?

SC copper cable lugs are used to terminate copper cables and connect them to busbars, electrical equipment and bolted terminals.

2. How do I choose the correct SC cable lug?

Check the conductor cross-section, conductor construction, barrel inside diameter, stud size and crimping tool requirements.

3. What is the advantage of tin-plated copper cable lugs?

Tin plating helps protect the copper surface against oxidation and supports stable electrical contact when the connection is properly installed.

4. Are SC cable lugs the same as DIN 46235 cable lugs?

Not necessarily. SC tubular cable lugs may have different barrel dimensions and lengths. Check the exact product dimensions and crimping requirements instead of assuming interchangeability.

5. Can SC copper lugs be used with aluminum cables?

Standard copper cable lugs are intended for compatible copper conductors. Aluminum or copper-to-aluminum connections require specifically suitable terminals and installation procedures.
