Detailed Description
Overview
This cable lug is designed to terminate a 300 mm² copper conductor and allow secure bolting onto a 16 mm (M16) stud or bolt. It is constructed from high-conductivity annealed copper and finished with tin plating to prevent corrosion and maintain good electrical performance.
Key Features & Benefits
-
High purity copper (annealed) for excellent conductivity and ductility
-
Tin plating (5–10 microns typical) for corrosion resistance and enhanced contact surface
-
Seamless, solid barrel construction to ensure uniform compression and reliable connection
-
May include features like bell mouth / flared entry (for easier strand insertion)
-
Some versions might not have inspection hole (many large lugs drop inspection window) — e.g. HellermannTyton’s CL300-16 is described “all Copper Lugs above 240 mm² do not have an inspection hole.”
-
Compliant with recognized standards (e.g. AS4325 / IEC / DIN) — CABAC’s 300 mm lug spec mentions compliance with AS4325.1.
-
Suitable for heavy duty power distribution, transformer connections, switchgear, busbars, industrial installations

| Operating temperature | –55 °C to +155 °C (common spec for copper / tin lugs) |
| Torque recommendation | For M16 stud, CABAC spec lists ~ 190 Nm for 16 mm stud in their catalog. |
Installation / Usage Guidelines
-
Strip insulation cleanly, avoiding damage to strands.
-
Insert bare conductor fully into the barrel.
-
Use a proper crimping die/tool rated for 300 mm² copper lugs to make a uniform, solid crimp.
-
Mount the lug onto the M16 stud/bolt with appropriate washer and torque (avoid over-tightening).
-
After installation, inspect for mechanical firmness and electrical continuity.
-
For heavy-duty or outdoor installations, periodically check for loosening or corrosion, though tin plating helps reduce degradation.
Cautions & Tips
-
Always match your crimp tool / die to the lug’s size (300 mm²) — wrong tools compromise reliability.
-
Do not over-torque the M16 stud — too much force can deform or damage.
-
In connections involving dissimilar metals (copper to aluminum, etc.), consider using transition or bi-metallic lugs to reduce galvanic corrosion.
