HHD1 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 switch 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, grounding, etc., the switch electrical appliance contacts are disconnected in time to disconnect the three-phase power supply of the motor to protect the motor quickly and reliably.
The protector directly adjusts the motor current according to the rated current value marked on the motor nameplate, which is accurate, intuitive and convenient.
The protector adopts the start avoidance technology, the start 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 current value and category displayed by the protector after the fault protection are convenient for users to understand the cause and troubleshoot.
This series of protectors meets the requirements of GB/T 14048.4 standard.
