Cable for photovoltaic installations H1Z2Z2-K class B2 (CPR) Red 4mm NON-FLAMMABLE
Description
H1Z2Z2-K 4 mm2 solar cable red – class B2ca (CPR), non-flammable
H1Z2Z2-K 4 mm2 red photovoltaic cable is a professional, single-core solar cable with the highest fire reaction class B2ca-s1,d0,a1 compliant with CPR regulations. The ideal choice for installers who need a reliable connection between PV panels and inverters — in both rooftop and ground-mounted installations.
Why does B2ca matter? Fire reaction class B2ca-s1,d0,a1 is the highest fire reaction class available for solar cables. It means zero smoke emission and toxicity during fire — a crucial requirement for installations on public buildings, multi-family residential properties, and anywhere fire safety is a priority.
