When used indoors where impulse coordination is maintained, it can withstand induced lightning!
This booklet introduces impulse voltage as defined by the overvoltage category/JIS. The standard impulse withstand voltage for the "Noise Cut Transformer" is 5kV (5000V). Up to an impulse voltage of 5kV (standard shock voltage of 1.2/50μs as specified in JEC-0202), it can protect equipment from induced lightning without insulation breakdown. If you have concerns about impulse coordination or are using it in outdoor panels, please consider the NCT-K type or I4 type with an impulse withstand voltage of 10kV, or the NCT-K type and P type with an impulse withstand voltage of 30kV.
