PD319 series motor protectors are inplicated to AC 380V and AC 660V low voltage system,as new intelligent integrated device that protect and monitor low-volt asynchronous motor and increased-safety motor.Besides function of motor protecting,they can provide information that the device running and tripping,so avoid of errors caused by overloading,stop slewing,breaking phase,the three phase unbalance,creepage.They are used to eletrical power,landification,light industry,coal,paper industry,steel industry,textile industry,and so on..
Standards:GB3836.3-2000 GB14048.4-2003 IE255-5,
