Product Description

​The Phoenix Contact FLT-CP-3C-350 is a Type 1+2 combined lightning current and surge arrester designed to protect three-phase power supply networks (L1, L2, L3, PEN) with PE and N conductors installed in a single cable. It offers both lightning current and surge protection, coordinated following the AEC (Application Engineering Coordination) principle, ensuring reliable defense against transient overvoltages. The arrester features a high continuous operating voltage of 350 V AC, making it suitable for 230/400 V AC networks with significant voltage fluctuations. It also includes optical and remote fault indication capabilities, enhancing system monitoring and maintenance efficiency.
