3.2.1 Configuring device description
The capacity of the circuit breaker is generally selected according to 1.5~2 times of the rated current of
the inverter.
Since the output voltage of the inverter is PWM high-frequency pulse voltage, the leakage current is
unavoidable. It is recommended to select the B-type special leakage protector.
Easy to control, but frequently open and close of the contactor will cause the inverter to malfunction.
Improve the impact of power factor and three-phase imbalance on the system.
Suppress the effect of spike current on the input of the inverter.
Reduce external interference
Improve the anti-interference ability of the inverter and reduce the external interference of the inverter
reduce the external interference of the inverter
When the cable from the inverter to the motor exceeds 100 meters, it is recommended to install an AC
reactor to suppress harmonic voltage and reduce leakage current.
