Summary
This series of motor integrated protectors (hereinafter referred to as protectors) are suitable for AC 50Hz, rated working voltage 380V and below the power supply circuit and AC contactors and other switchgear to form a motor control circuit. When the main circuit of the motor appears abnormal working state such as phase break, overload and so on, disconnect the switch contact in time, break off the three-phase power supply of the motor, and protect the motor quickly and reliably. The protector is designed by American LM integrated circuit on the basis of digesting and absorbing foreign advanced technology. It has the advantages of complete function, high sensitivity, reliable action, small volume, convenient use and good reverse time limit characteristics. It can be widely used in industrial and agricultural production.
