HHD1F 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 loss, three-phase imbalance, overload, stall, etc., the switch electrical appliance contacts are disconnected in time to disconnect the three-phase power supply of the motor to quickly and reliably protect the motor.
The protector can directly adjust the motor protection current according to the rated current value marked on the motor nameplate, which is accurate, intuitive and convenient.
The protector adopts starting avoidance technology, the starting avoidance time is separated from the overload time, and the overload action has good inverse time characteristics.
The protector adopts fault current self-locking technology. The protector displays the current value at the time of the fault after the fault protection, which is convenient for users to understand the cause and troubleshoot.
