nVent ERIFLEX Flexibar Summum, Halogen Free

FLEXSM2MRC3X32 (566630)


  • Halogen free solution for applications requiring a low smoke solution
  • Thin layers of bare electrolytic copper formed into a stack
  • Silver or tinned nVent ERIFLEX Flexibar Summum available on request
  • Insulated by halogen-free, high-temperature silicone
  • Easily bent, folded, and twisted, improving assembly flexibility, shortening connections, and decreasing footprint
  • Dramatically smaller and more flexible than comparable cable based on ampacity
  • Better power density than cable with lower skin effect ratio
  • Connections made by punching and bolting directly through the copper laminates, clamping onto the end of the nVent ERIFLEX Flexibar, or welding using nVent ERICO Cadweld
  • No lugs needed, reducing installation time and improving resistance to vibration
  • Weight savings and material savings compared to wire alternatives
  • Reduces total installation cost
  • Very high resistance to UV and ozone
  • Limiting oxygen index (LOI)
  • Traceability codes and designation part numbers printed on insulation
  • Conforms to NF EN 45545 obtaining an HL2 classification for chapters R22 and R23
  • EAC compliant
  • RoHS compliant
