Product catalog summary
Product Overview: The nVent ERIFLEX Flexibar is a flexible electrical conductor made from thin layers of bare electrolytic copper. It is available in a range of sizes from 19.5 mm² to 1200 mm² and supports current ratings from 125 A to 2800 A. The product is insulated with high-resistance, self-extinguishing PVC, which covers less than 20% of the conductor, allowing for high flexibility.
Key Features:
  • Flexibility: The Flexibar can be easily bent, folded, and twisted, which enhances assembly flexibility, shortens connections, and reduces the installation footprint.
  • Installation: Connections can be made by punching and bolting through the copper laminates, clamping, or welding using nVent ERICO Cadweld, eliminating the need for lugs and reducing installation time.
  • Cost Efficiency: Offers weight and material savings compared to wire alternatives, reducing total installation costs.
  • Compliance and Testing: The product is 100% production dielectric tested and complies with UL 758 Appliance Wiring Material requirements for cold bend testing at -40°C and -50°C. It is also EAC and RoHS compliant.
Technical Specifications:
  • Length: 2000 mm
  • Material: Copper, Polyvinylchloride
  • Dielectric Strength: 20 kV/mm
  • Flammability Rating: UL 94V-0
  • Insulation Elongation: 370%
  • Insulation Thickness: 2 mm
  • Nominal Voltage: 1000 VAC, 1500 VDC
  • Working Temperature: -50 to 105 °C
  • Forming Temperature: 0 – 55 °C
  • Certifications: UL 67, UL 758, IEC 60439.1, IEC 61439.1, IEC 60695-2-11 (Glow Wire Test 960 °C)
Performance Data: The document provides a detailed table of current ratings for various part numbers, indicating the temperature rise (∆T) at different current levels (40 K, 50 K, 60 K). The table also includes dimensions and cross-sectional areas for each part number.
Warnings: nVent products must be installed and used according to the provided instruction sheets and training materials. Improper installation or misuse may lead to product malfunction, property damage, serious injury, or death, and may void the warranty.
Legal and Trademark Information: The document includes legal disclaimers and trademark information, noting that nVent reserves the right to change specifications without prior notice.
