Belcom Double Pair RS485 Cable 4-Core LSZH — Priced per Metre
The Belcom 4402P2454 is a double-pair, 4-core, 24 AWG shielded RS485 data cable designed for reliable Modbus and RS485 communication in solar PV, building automation, and industrial control applications. The 4 cores are twisted as two pairs — ideal for RS485 A/B plus ground and shield drain — with an overall aluminium/polyester tape screen and 80% tinned copper braid for superior noise rejection. The LSZH FireFighter® UV-stable outer jacket makes it suitable for both indoor and exposed outdoor runs. Sold and priced per metre.

Frequently Asked Questions
Is this cable suitable for wiring a SolarEdge energy meter to an inverter?
Yes — this cable fully meets the SolarEdge RS485 wiring specification: minimum 3-wire shielded twisted pair, 0.2–1 mm² (24–18 AWG). The 4-core format gives you a dedicated pair for RS485 A and B, plus extra cores for GND and shield termination. Use one pair for RS485 A/B and terminate the screen drain wire at one end only (typically at the inverter end) to avoid ground loops.
Why does it need double shielding (foil + braid)?
In solar PV installations, RS485 cables often run near DC cables, inverters, and switching equipment that generate electrical noise. The aluminium/polyester foil provides 100% coverage against high-frequency interference, while the 80% tinned copper braid adds mechanical protection and improves low-frequency shielding. Together they ensure reliable communication over long runs in electrically noisy environments.
How much cable do I need for a typical SolarEdge meter installation?
The CT lead wires are 2.4 m long, so the meter should ideally be mounted within 2.4 m of the main incomer. Allow enough RS485 cable to run from the meter terminal to the inverter RS485 port — typically 3–10 m for a standard domestic installation where the consumer unit and inverter are in the same area, or more for commercial sites where equipment is spread across multiple rooms. SolarEdge recommends external surge protection for runs over 10 m in lightning-risk areas.
