Core Features & Benefits (SEO Keywords: Heat Shrink Terminal, Sealed Connection, Corrosion Resistant)

Permanent Environmental Seal: The integrated adhesive-lined heat shrink tube melts during installation, creating a waterproof, dustproof, and airtight seal. This protects the copper connection from moisture, chemicals, and corrosion, ensuring long-term reliability in harsh environments.

Exceptional Electrical Insulation: Provides high dielectric strength and excellent insulation resistance, enhancing electrical safety and preventing short circuits.

Robust Mechanical Protection: The thick-walled tubing offers superior strain relief and mechanical durability, safeguarding the connection from vibration, abrasion, and physical impact.

High-Quality Copper Construction: Made from electrolytic copper (tin-plated for the FEN-31T version), ensuring excellent conductivity, low resistance, and resistance to oxidation.

Easy & Secure Installation: Quick installation with a standard heat gun. The transparent tubing section allows for visual inspection of the cable position, guaranteeing a proper crimp.

Wide Range: Available in a comprehensive selection of sizes to accommodate cable cross-sections, with options for tin-plated (FEN-31T) or non-tin-plated copper, and various stud hole diameters.

Technical Specifications & Compliance

Standards: Compliant with IEC 61238-1 for compression connections.

Operating Temperature: Typically -40°C to +110°C.

Material: Polyolefin tubing with sealant adhesive, electrolytic copper lug.

Color: Standard red for easy phase identification (other colors may be available).
