HHD11-A phase sequence protection relay (hereinafter referred to as protection relay) is suitable for AC 50Hz, 380V power supply circuit and AC contactor and other switching electrical appliances to form motor control circuit. When the main circuit of the motor is in an abnormal state such as phase mismatch, the switch electrical appliance contacts are disconnected in time to disconnect the three-phase power supply of the motor, quickly and reliably protecting the motor.
The protection relay adopts voltage sampling mode, which is independent of the power size of the motor and does not require any current level setting and adjustment. The whole machine has the advantages of wide application range, simple and convenient use, stable and reliable performance, etc.
This series of protection relays meets the relevant requirements of GB/T 14048.4.
