HHD3E series motor protector (hereinafter referred to as protector) is suitable for AC 50Hz, rated working voltage AC380V and below power supply circuit and AC contactor and other switching electrical appliances to form motor control circuit. When the main circuit of the motor has abnormal working conditions such as phase failure and overload, the switch electrical appliance contacts are disconnected in time to disconnect the three-phase power supply of the motor, and the motor is protected quickly and reliably. The protector adopts the potentiometer quantitative setting method, and directly adjusts the setting current of the protector according to the rated current value marked on the motor nameplate, which is more convenient and intuitive than the setting method of non-quantitative setting and starting the motor. The protector adopts the starting avoidance continuous adjustable technology, and the overload has excellent inverse time performance, which can meet the needs of various motors from light load to heavy load starting. This protector has an invention patent.
This series of protectors meets the requirements of GB/T 14048.4 standard.
