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

Description

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.

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.
