Overview
The Panduit LCC350-12-X is a tin-plated copper compression lug engineered for high-amperage electrical applications. This 2-hole, long barrel mechanical lug is designed for 350 kcmil copper conductors and features robust construction for secure, reliable terminations in industrial and utility power distribution systems.
Key Features
- Tin-plated copper construction resists corrosion and oxidation
- Long barrel design maximizes the number of crimps for premium pull-out strength
- Color-coded barrel with Panduit and competitor die index numbers for proper crimp die selection
- Generously beveled wire entry prevents bent-back strands during conductor insertion
- Two-hole configuration with 1-3/4″ hole spacing for mounting versatility
- Inspection window allows visual confirmation of full conductor insertion
- UL Listed and CSA Certified for 35 kV applications
