UNITRONIC® BUS PB FRNC FC
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
Benefits
- 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
- Oil-resistant
