    Why is the leakage circuit breaker easy to trip when using the inverter?
    This is because the output waveform of the inverter contains high-order harmonics, and the motor and the cable between the inverter and the motor will generate a leakage current, which is much larger than that when the motor is driven by commercial frequency, so this phenomenon occurs.
    The leakage current on the output side of the inverter operation is more than 3 times of the power frequency operation, plus the leakage current of the motor, etc., the operating current of the leakage protector should be greater than 10 times the leakage current of the power frequency.
