Notices
● Install the SPD in LPZ 0B-1 or subsequent lightning protection zones to ensure effective T2 protection.
● Use wiring with cross-sectional area 2.5mm²-32mm² and tighten screws to 5N·m torque.
● Regularly check the indication window—replace the product immediately if it turns red (failure status).
● Ensure the grounding system meets requirements (ground resistance ≤4Ω) for optimal surge diversion.
● Select the appropriate model based on the required discharge current (40kA/50kA/80kA/100kA).
● Avoid using the product beyond the specified temperature (-40℃~+80℃) and humidity range.
FAQ
Q1: What is the difference between the models in the series?
A1: The main difference is nominal discharge current (In) and maximum discharge current (Imax): LPM 40-385/4 (40kA/80kA), LPM 50-385/4 (50kA/100kA), LPM 80-385/4 (80kA/160kA), LPM 100-385/4 (100kA/200kA).
Q2: Does the product support remote monitoring?
A2: Yes, it is equipped with normally closed and normally open remote signaling contacts, enabling connection to monitoring systems for remote status tracking.
Q3: What is the function of the built-in ultra-low temperature release mechanism?
A3: It ensures the product operates safely in low-temperature environments (-40℃) and disconnects faulty modules to avoid hazards.
Q4: Can it be used in 400V three-phase systems?
A4: Yes, with maximum continuous operating voltage 385Vac, it is compatible with 400V three-phase systems (230V phase-neutral).
Q5: What is the flame-retardant grade of the housing?
A5: The housing is made of mineral nylon PA6 with V0 flame-retardant grade, which self-extinguishes within 10 seconds after ignition.
