FLP10 with Failure Indicator 20kV lightning surge arrester

FATECH FLP10-i series, covering FLP10-150i‑P/BG, FLP10-150i‑S/BG, FLP10-275i‑P/BG, FLP10-275i‑S/BG, FLP10-320i‑P/BG, FLP10-320i‑S/BG, FLP10-385i‑P/BG and FLP10-385i‑S/BG, are Class II+III/C+D/T2+T3 combined surge protective devices customized for LED street light systems.

Designed for 120V, 230V and 380V outdoor lighting networks, this SPD series offers continuous operating voltages of 150V, 275V, 320V and 385V. It achieves a maximum discharge current of 20kA and a nominal discharge current of 10kA, with well‑graded voltage protection levels for L‑N and N‑PE loops. The response time is ≤25ns for L‑N and ≤100ns for L/N‑PE, providing efficient suppression of transient surge overvoltage.

Equipped with internal thermal cut-off and multi-protection modes including L-N, N-PE and L-PE, the unit adds a LED failure indicator for real-time working status monitoring, which is the core difference from the standard FLP10 series. Featuring IP66 high outdoor protection, UL94V-0 flame retardant housing, wide temperature tolerance of -40°C~+80°C and applicable altitude up to 3000m, it is highly reliable for long-term outdoor operation and serves as an optimal lightning and overvoltage protection solution for LED street lights and outdoor lighting projects.
