    Existing reviews of 75kVA 3-Phase 400v 50Hz/240v 60Hz Frequency Converter
    High quality 3 phase 75 kVA frequency converter
    For your 75 kVA 3 phase frequency converter, the 104.2A is that inrush current or nominal current? The in-rush current duration for my application is less than 0.5 seconds and the nominal is ~ 11 amps. Would I still require a 75kVA unit?

    The 104.2A is the max inrush current the frequency converter can handle, so, even the in-rush current duration for your application is less than 0.5 seconds, recommended converter would be 75kVA as listed below.
