Scope of application

The XJD1 series autotransformer voltage reducing starter box is suitable for three-phase squirrel cage induction motors with AC power ranging from 380V to 300kW for voltage reduction starting. It uses an autotransformer voltage reducing method to improve the impact on the transmission network when the motor starts.
