Installation Tips
1.Install the lightning protection box in a dry, well-ventilated indoor environment, away from flammable materials.
2.Use wires with cross-sectional area 2.5mm²~10mm², and tighten the screws to 5N·m torque.
3.Ensure reliable grounding with ground resistance ≤4Ω to ensure optimal surge diversion effect.
4.Regularly check the lightning strike counter and LED status indicator; replace the product immediately if it fails.
5.Do not disassemble the product without authorization to avoid damage to internal components.
FAQ
Q1: What is Kevin Connection and when should it be used?
A1: Kevin Connection is a wiring method that minimizes current measurement errors. It is recommended for large current applications (≥25kA) to ensure accurate protection triggering.
Q2: Can it be used in 400V three-phase systems?
A2: Yes, with maximum continuous operating voltage 385Vac, it is compatible with 400V three-phase systems (230V phase-neutral).
Q3: What is the difference between T1 and T2 level protection?
A3: T1 level handles direct lightning strikes (10/350μs waveform), while T2 level protects against indirect surges (8/20μs waveform). This product integrates both for comprehensive protection.
Q4: What is the flame-retardant grade of the housing?
A4: The housing is made of mineral nylon PA6 with V0 flame-retardant grade, which self-extinguishes within 10 seconds after ignition.
Q5: What is the response time of the product?
A5: The response time is ≤100ns, ensuring rapid diversion of surge current to protect sensitive equipment.
