Fixed installation

Bus cable for PROFIBUS-DP, -FMS and FIP. Cable is UL/CSA-certified, halogen-free, has enhanced flame retardance, oil resistance. Temperature range from -30°C to +80°C

FRNC = Flame Retardant Non Corrosive
- Reduction of flame propagation and
density and toxicity of smoke gases
in the event of fire
- Minimisation of fire damage to buildings
and production facilities
- Safety for maintenance personnel and
in areas with a high density of people

  • Halogen-free and highly flame-retardant
  • Cables can be used for PROFIBUS-DP as well as PROFIBUS-FMS and FIP
  • For use wherever the combination of a halogen-free outer sheath with properties similar to polyurethane and enhanced flame-retardance is required
  • Fast Connect (FC) cable design

Application range

  • This cable provides special advantages in sensitive areas where fire propagation must be avoided and the presence of toxic fumes in the event of a fire would cause personal injury and damage to equipment.

Product features

  • The cable is UL/CSA-certified (CMG)
  • Halogen-free
  • Highly flame-retardant in accordance with IEC 60332-3 and FT4
