XJZ1 Series Auto-Reducing Voltage Starting Control Cabinet

Function and Use

The XJZ1 series autotransformer voltage reduction starting control box is suitable for three-phase squirrel cage induction motors with an AC frequency of 50 Hz, rated voltage of 380 V, and rated output power of 300 kW or less for infrequent voltage reduction starting. It can manually disconnect the motor's power circuit (not suitable for the jogging, reverse connection braking, or reversing of squirrel cage induction motors, nor for circuits that frequently switch on and off or suddenly reverse the motor). Conforms to the standard: GB/T 14048.4.
