Belcom FireFighter 2x2x22AWG RS485 Cable LSZH | 4302P2254-01 | 600V

The Belcom FireFighter 430 Series 4302P2254-01 is a 2 pair, 22AWG low capacitance RS485 / TIA-485 control cable built for interference-free, high-speed data transmission in demanding installations. It combines an overall aluminium/polyester foil screen with a tinned copper braid (65% coverage) and a stranded tinned copper drain wire for a high level of noise protection. The black LSZH FireFighter SHF-1 outer jacket delivers low smoke, zero halogen performance with Euroclass Dca,s1,d2,a1 classification, making it a sound choice where fire behaviour matters. It suits Modbus, BACnet MS/TP, HART and CanOpen networks, with a 600 V rating, a -20°C to +90°C temperature range and UV resistance to ISO 4892-2/A. 2 x 2 Pairs x 22AWG 120 Ω Nominal impedance 36.1 pF/m Capacitance (cond./cond.) 78% Velocity of propagation 600 V Rated voltage Dca,s1,d2,a1 Euroclass Fire and installation compliance: Cable selection and fire performance must meet the project specification and BS 7671 requirements. Confirm the required cable class for the building before installing. Please note: The Euroclass rating includes d2, which places no limit on flaming droplets. All values are nominal; the overall diameter is quoted at ±10% and values should be treated as a guide. Pair colour code: Pair 1 is white/blue paired with blue/white. Pair 2 is white/orange paired with orange/white. Key Features Double screening Aluminium/polyester foil plus 65% tinned copper braid with a drain wire for enhanced noise protection in harsh environments. Low capacitance 36.1 pF/m conductor-to-conductor supports reliable high-speed RS485 data transmission. LSZH jacket FireFighter SHF-1 Low Smoke Zero Halogen compound, halogen free to IEC 60754 and low smoke to IEC 61034. Flame and fire retardant Flame retardant to IEC 60332-1 and fire retardant to IEC 60332-3-24. Stranded tinned copper 22AWG stranded tinned copper conductors with polyethylene (PE) insulation for flexibility and corrosion resistance.
